Your first bees

June is a good time to start keeping bees.

The long, cold, dark winter is a distant memory. The uncertainties of spring – the unseasonably warm days in March, the April (snow) showers, the “will they, won’t they” doubts over spring build up (in a cold year) or early swarming (in a warm one) – are over. 

If you did a ‘start beekeeping’ course in the winter then waiting until June to get bees might feel like a lifetime, but it actually makes a lot of sense.

You miss the roller coaster ride that spring sometimes provides. In a bad year, starvation or swarming can leave you without bees by the end of May 🙁

Instead, you benefit from better (more settled) weather, stronger colonies and at least three months to get to confidently work with your bees as you – hopefully – get some summer honey and prepare them for the winter ahead.

Buy local bees

There are compelling reasons to buy local bees. By this I mean queens reared locally.

More locally reared queens …

Not Greece or Italy 1, imported in large batches and dropped into a box of ‘local’ workers, all of whom will be replaced within a month. These are effectively bees from southern Europe and are quite possibly not suited to Cumbria or Essex 2.

Several scientific studies have shown that locally reared bees do better than imports, particularly when overwintering. 

But the benefits don’t end there. If you buy bees locally you’ll probably buy them from a local beekeeper 3. I’ve proposed before that this could be your mentor … and that, ideally, you could have helped split the nuc from a strong colony, watched it develop and then purchased it.

But that’s not always possible. Mentoring is time consuming and dependent on the organisation of the local beekeeping association, to say nothing of simple geographic factors 4 or Covid and social distancing.

When you buy local bees you should expect to get some of the ‘back story’ on the colony. When was the queen grafted, when did she start to lay? 

If you do agree to buy bees from a local beekeeper, don’t then go and then buy them from someone else. Preparing nucs is time-consuming and involves committing resources from honey production or making increase. At the very least, a beekeeper reserving a nuc for you probably means s/he is turning other potential purchasers away. Have some courtesy.

A 5 frame nuc when sold should contain a frame of stores, a laying queen (!) – clipped or marked if requested  – and 3-4 frames of brood in all stages.

There should be sealed brood in the colony laid by the queen heading the colony.

OK, enough preamble … what about the practicalities of getting the bees home, installing them in a hive and doing your first inspection?

Transporting bees

If you are collecting your nuc from a local apiary it will probably already be sealed up for transport. The entrance should be sealed securely and the frames should be wedged in place so they won’t flap around during transit. I use closed cell foam blocks for this, but it may not be necessary in some smaller nuc boxes.

Preparing a nuc for transport. Note the foam block to secure the frames.

You might not be provided with a strap, so bring your own. Ratchet straps are probably overkill for a nuc, but they certainly do the job. Gaffer tape works well, as do these ‘no moving parts but can I remember how they work?’ hive straps.

Standard hive straps

If you collect them at the beginning or end of the day there will be more bees in the box and fewer foragers out, er, foraging.

It’s always good to actually get the bees you’re paying for 😉

More importantly, it’s also cooler at the start or end of the day, which is one less thing to be concerned about when transporting bees. Since you’re buying locally you won’t be transporting the bees far. That being the case, it’s usually sufficient to make sure there’s good airflow under the open mesh floor, without using a travel screen.

If you move bees in the heat of the day expect to have to use some sort of mesh screen over the top of the frames. The last thing you want is overheating and stressed bees. 

Mesh and staples

Actually, that’s the penultimate thing.

The last thing you want is the combs melting and collapsing … avoid this at all costs.

Escapees

Secure the nuc in the car 5 so that it can’t tip over. The frames should be in line with the direction of travel.

It’s not the end of the world if they’re perpendicular to travel, but it reduces the ‘frame flap’ when accelerating and decelerating. 

I often put the bees on the car seat, strapped in place with a seat belt, with a sheet or two of newspaper underneath the OMF to stop getting nectar or pollen on the nappa leather upholstery my filthy car from soiling the nuc box.

I’ve moved dozens of nucs like this and never had a problem.

Drive carefully.

You might find one or two bees “escaping”. In my experience these are more likely to be ‘hitchhikers’ who were underneath the open mesh floor, rather than Houdini-like bees that have circumvented the sealed entrance of the nuc 6.

Stop and let them out at the earliest opportunity … it’s safer and they’re more likely to get back to the home apiary.

If you’re 10 miles away from the apiary their fate is probably sealed 🙁

Opening the hive entrance

Bees can be a bit disoriented and distressed after a car journey.

Therefore, don’t be in a rush to open them up too soon.

I always place them in the location they are going to be permanently sited and leave them for at least half an hour.

Then, and only then, I gently open the hive entrance.

If you do it as soon as you arrive the bees may come flooding out … if you leave them to settle they will be much calmer.

Correx, the beekeepers friend ...

Correx, the beekeepers friend …

Don’t bump or rock the hive.

Don’t wrestle with the sealed entrance.

Hopefully the 30+ minutes recuperation time has allowed you to work out a strategy to open the hive entrance with the minimum disturbance possible.

Those rotating entrance disks have got a lot to commend them 🙂

Ideally you want the bees to be barely aware that the entrance is now open when it wasn’t a moment before … for example, there’s usually no need for smoke 7.

Remember, the bees know nothing about their new environment. You want them to explore it at their own pace, rather than releasing a few thousand agitated bees all at once.

Open the entrance so the bees can come and go, but don’t leave a cavernous maw gaping that they might struggle to defend,

Take a few steps back and enjoy watching the first orientation flights of your new bees.

And that’s it for the day … leave them in peace.

Transferring the nuc to a full hive

At this time of the season the bees will rapidly outgrow a 5 frame nucleus hive. If you leave them in there too long the queen will run out of space to lay and they’ll start to think about swarming.

Remember that overcrowding is one of the (many) triggers for swarming and, once they’ve decided to go, it can be very difficult to stop them.

Here's one I prepared earlier

Here’s one I prepared earlier … an overcrowded overwintered nuc in April

Therefore you need to transfer them to a full-sized hive within – at most – a few days of acquiring them 8.

You will need a full hive – floor, brood box, crownboard and roof – together with five or six (or 7 for the new Abelo boxes I see) frames with foundation fitted 9.

Frame orientation – frames from nuc in red, new foundation in grey

Since this is probably also the first time you are going to open the nuc (and, if it’s not, why did you look earlier? See the final section of this post.) you’ll also need a beesuit, hive tool and smoker.

  • Move the nuc gently to one side and place the new floor and brood box where the nuc was, with the entrance facing the same direction.
  • Gently smoke the nuc. Just a couple of puffs near the entrance should be more than sufficient. You don’t need to ‘kipper them’.
  • Transfer the 3-4 frames of brood one at a time, placing them next to each other in the new hive. By all means have a brief look at each side of the frames, but place them in the new hive in the same orientation with regard to their neighbours. The goal here is that the brood nest is not unduly disturbed.
  • Flank these with a frame or two of foundation and then add the frame of stores.
  • If I’m arranging the frames the ‘warm way’ i.e. parallel to the hive entrance, I’ll place the occupied brood frames closer to the entrance. This helps the colony defend the entrance. If the frames are perpendicular to the entrance (the cold way) I place them in the middle of the hive 10.

Add the crownboard and roof. 

All done.

Feeding the colony

Probably the first dilemma faced by a new beekeeper is whether to feed the recently re-hived nucleus colony. 

This is what beekeeping is all about … making judgement calls based upon the strength and state of the colony, in the context of the local environment and with an understanding of what the weather is going to be like over the next week or two.

Get used to it … you’ll be making a lot of decisions like this 😉

Here are a couple of scenarios …

  1. Unseasonably cold weather with lots of rain and an understrength nucleus colony.
  2. Warm, settled weather with a very strong nucleus colony in an environment with abundant forage.

The first must be fed for it to survive, let alone thrive.

The second may well not need feeding at all.

It’s best to err on the side of caution and feed nucs if there’s any doubt they will not have enough nectar to draw fresh comb and expand the brood nest. 

This spring – at least since late May – the nectar flow has been exceptional and I’ve not fed any nucs. All have drawn comb ‘for fun’, often drawing successive frames one after another that I’ve rotated into the box.

If the colony does need feeding I prefer to use a contact feeder (a plastic bucket with a fine mesh grille in the lid inverted over the brood nest) containing 1:1 (by weight) syrup made of granulated sugar and water.

Welcome to your new home … nuc ‘promoted’ to hive with contact feeder in place

The aim it to imitate a good nectar flow rather than allow the bees to store large amount of syrup stores. You want them to draw new comb and rear lots of new brood.

I place the contact feeder directly over the top bars, separated by a couple of wooden spacers. I do this because most of my crownboards lack central holes. Use a spare super to enclose the contact feeder.

I think my contact feeders are ‘half gallon’ ones … they are just big enough to take a mix of 2 litres of water and 2 kg of sugar 11. If the weather remains poor, or the nectar remains elusive (you could always ask the local beekeeper you bought the nuc from … another advantage of buying local bees 😉 ), then it will do no harm to give them a second ‘half gallon’ of syrup to help them build up.

Do not spill syrup in the apiary. It encourages robbing and your new colony may not be able to defend itself. If in doubt, again err on the side of caution … reduce the entrance size of the hive.

Inspections and enjoyment

On a warm, calm, settled day you should conduct your first colony inspection. Nucs, even recently promoted ones in a full hive, are usually a pleasure to inspect. There are sufficiently small numbers of bees that you should be able to see what’s going on relatively easily.

Don’t worry about finding the queen. If there are eggs present and no sealed queen cells then she will be in the hive.

Marked queen surrounded by a retinue of workers.

They’re not always this obvious …

It’s always a bit risky making assurances like that as I can think of several scenarios when I would be wrong.

If there are eggs present then there was a queen in the hive within the last 3 days 12.

If there are sealed queen cells present then it’s possible that the hive has swarmed.

But what about eggs being present together with unsealed queen cells?

That'll do nicely

That’ll do nicely …

There are two obvious explanations, one of which is much more likely for a new beekeeper with their first colony:

  • The colony was dead set on swarming and has swarmed without waiting for the queen cell to be sealed. This happens, but it’s unlikely to occur with a nucleus colony just moved to a new hive 13.
  • The queen has very recently died – or, more accurately, been killed – and the bees are rearing new queen cells under the emergency impulse,

New beekeepers are understandably enthusiastic … but they can be clumsy.

It’s not unusual for a queen to be damaged or killed during a colony inspection by an inexperienced beekeeper 14. It’s easy to squidge the queen between the sidebars of the frame and the brood box, perhaps because she’s rushing about after the colony was smoked too much, or between frames when returning them to the hive.

If you can’t find the queen you can’t be sure where she is.

Accidents happen.

This was almost certainly the fate of my first ever queen which disappeared a week or two after I bought my nuc … and I thought I was being so careful 🙁

Which brings me to my last couple of points. 

Do not inspect the colony more than necessary.

Once every seven days is sufficient. Don’t meddle. Let them get on with things. When they get to 7-8 frames of brood add a queen excluder and a super. 

Observe and enjoy them … from a distance. 

Congratulations … you’re now a beekeeper 🙂


 

Hard graft

Regular readers will have seen this image before …

Swarmy weather? I don’t think so …

… as I used it (with the same legend) towards the end of the post last week. 

I spoke too soon 🙁

The temperature on the 17th and 18th briefly reached 17.5°C … which was enough.

Grrrr …

But I’m getting ahead of myself.

Good morning America Glenrothes

I’m fortunate to live in a stunningly beautiful and remote part of the country. I open the blinds in the morning to panoramic views of the Morvern hills across a narrow sea loch. There are no houses in direct sight and – even when it’s damp 1 – it’s an idyllic scene.

Good morning Morvern …

But although I live here, most of my bees still live in Fife, so I have a commute to look after them and stay in convenient 2 hotels.

Opening the curtains on these trips provides a somewhat less salubrious view.

Uninterrupted views of the Macdonald’s drive-in

But at least I don’t have to cook my own breakfast, which is but a short walk away 🙂

As you can see from the photo above, it’s been raining overnight.

To make these trips economically rational 3 it’s necessary to book them several weeks in advance.

Despite the use of supercomputers, the BBC’s medium to long-range weather forecasts seem little more than guesswork. It’s worth remembering that a weather forecast competition over several weeks was won by a team that predicted ‘tomorrow will be like today’ for the duration of the event 4.

And for beekeeping, there’s a significant difference between 12°C, light drizzle with strong winds and 13°C, intermittent sunshine and gentle breezes.

The latter makes opening hives a relatively straightforward proposition … careful and quick, but the bees will cope just fine.

In contrast, the former makes everything rather hard work.

And this morning we’ll graft delicate larvae no larger than a comma on a page …

And these are exactly the conditions that greeted me when I did my first round of grafting on the 10th of May.

The weather is probably the major problem of long distance beekeeping. You have to be prepared for anything.

Queenright cell raising – the Ben Harden system

I’ve discussed grafting and using the Ben Harden queenright cell raising system extensively before. 

My Ben Harden setup was in the bee shed.

As it turned out, this was a (disappointingly rare) stroke of genius.

A strong, double brood colony had been modified be the replacement of 7 frames in the upper box by two ‘fat dummies‘. These have the effect of concentrating the bees in the gap between them. 

In this space were two frames containing pollen, one frame of young larvae 5 and the cell bar frame, into which I would be grafting larvae.

Ben Harden setup and pollen patties

This box sits on top of a queen excluder, below which was a single brood box (containing the queen) literally overflowing with bees 6. Positively bulging at the seams.

Since I didn’t have frames with sufficient pollen in them I’d also supplemented the colony with pollen substitute (a pollen pattie) which they were happily devouring. 

The hive also had a couple of half-full supers. These contained lots of bees but rather disappointing amounts of nectar.

The queen providing the larvae was in a nuc box in the same apiary. I’d been feeding this colony syrup and pollen to ensure the young larvae were well fed 7.

Grafting

The day for grafting dawned cool, grey and drizzly.

Great 🙁

I ended up doing the grafting in the passenger seat of the car, wearing a headtorch. I kept the larvae warm and humid using a damp piece of kitchen paper draped over those I’d already transferred from the comb to the plastic cups in the cell bar frame.

After gently inserting the cell bar frame into the space in the centre of the Ben Harden setup and filling the feeder in the fat dummy with syrup, I added a clearer board and then replaced the two supers.

The intention was to empty the supers into the cell rearing box, guaranteeing a huge number of bees would be there to help raise the queens.

Ben Harden cell raiser with clearer and supers

After another evening of junk food and a disappointingly similar breakfast I checked the grafts the next day for ‘acceptance’.

10/10 …

You do this by – ever so gently – lifting the cell bar frame from the centre of the Ben Harden setup and looking for a 5-6mm collar of fresh wax built around the lower lip of the Nicot cup into which the larvae have been grafted.

Amazingly, considering the dodgy conditions and the fact that this was my first attempt at grafting for a couple of years, all the larvae appeared to have been accepted 8. I didn’t brush any of the bees off and I certainly didn’t prod about in the densely packed bees on the frame … but things looked good.

So I closed the hive up and went off to inspect some other colonies in the rain before driving back to the west coast.

Coffee mishaps and colony inspections

I returned to the east coast about 8-9 days later to add the queen cells to nucleus colonies.

The ~150 mile journey didn’t go well. In mid-slurp the lid came off my mug, depositing a lap-full of lukewarm coffee over me. 

Never mind. The route I take goes through some ‘modesty-ensuring’ remote countryside. It was a five minute task to leave the trousers drying over the boxes of frames in the back of the car.

Since I had no spares I donned my beesuit and continued on the journey.

The weather improved as I drove east. I checked an apiary in mid-Fife where all was well and finally arrived at my main apiary in mid-afternoon.

It was a lovely day 🙂

So lovely one of the colonies had swarmed 🙁

There were actually two small swarms hanging about a metre apart in the willow trees I’d planted around the apiary 9

I didn’t really have time to think about the swarm … we needed a few hundred early stage drone pupae for work so went through the colonies to find these first.

These were quick ‘n’ dirty inspections … I checked every frame, but not every cell or every nook and crannie … 

  • brood in all stages?
  • eggs?
  • stores?
  • any charged queen cells?
  • temper, behaviour, stable on the comb?
  • anything weird or strange? 10
  • next please …

I didn’t check the hive I’d set up for queen rearing, or any of the nucs on site that contained virgin queens. However, all of the other colonies were queenright as determined by the presence of eggs and the absence of (obvious 11 ) queen cells.

Drone brood was either present in relative abundance – in the strong colonies – or notable by its absence. This should not be unexpected to those of you who read the post on drones last week.

To the tune of ‘Ten green bottles’ … all together now, ‘Ten capped queen cells hanging on a frame …’

And I still had 10 queen cells in the cell raising colony, all now capped and ready to use the following day 🙂

And the swarm?

The swarm (either of them if there were actually two) wasn’t really big enough to be a prime swarm. These contain a mated queen and ~75% of the workforce from the hive. None of the hives appeared short of bees and I’d found no (obvious 12 ) charged queen cells.

However, I’d not checked the queen rearing colony – packed full of bees and fed copious amounts of syrup – and one of the colonies on the site was very bad tempered 13.

Poor temper is often a sign of a queenless colony.

Anyway, back to the swarm.

I dropped each clump of bees into a separate nuc box containing a frame of drawn comb and a couple of additional frames. I left these in the shade until late afternoon when I’d finished with the other colonies.

Two into one do go

By late afternoon most of the swarm bees from one of the nuc boxes had abandoned it and joined the other nuc box. It was pretty clear that there was only one ‘swarm’ and that it had got separated when settling at the bivouac.

The bees were leaving the queenless box and joining the queenright one.

I checked the willow where the swarm was found. 

Small amounts of wax where a swarm settled

There were small amounts of wax deposited on the leaves and stem of the willow. I suspect that the swarm may therefore have been there overnight 14 but can’t be sure.

I ended the afternoon by putting the hived swarm on a hive stand in the apiary.

Before leaving I checked the bad tempered colony (which I was intending to split into nucs the following day).

During my fumblings I managed to get a few bees into my beesuit pocket 15.

The one with the hole in it from my razor-sharp hive tool.

That opened onto my leg.

Which was unprotected by trousers due to my fumblings with the coffee 9 hours earlier 🙁

Ouch 🙁

Getting nuked

The weather the following day started bright but rapidly degenerated.

That lot is about 10 minutes away … and approaching fast

By the time I’d got the nuc boxes prepared – feeders, frames, stores, dummy boards, entrance blocks, labels, straps – it was 11°C and there was rain quickly approaching from the west.

The first four nucs were prepared from the ‘bad tempered’ hive (#6). I decided it was wise to get this over and done with before the heaven’s opened.

Despite going through the box twice I failed to find a queen. Perhaps she went with the smallest prime swarm ever?

I divided the frames (by brood and bees, not number of frames) into four approximately equal nucs and added a queen cell to each. 

Here’s one I produced earlier … or helped produce

Each queen cell was removed from the cell bar frame, the adhering bees gently brushed off (with a handful of weeds) and pressed into a thumb-sized indentation in the comb, just underneath the top bar of the frame.

I then carefully pushed the frames together (avoiding crushing the cell) and closed the nuc box up.

As I opened the next hive to be split the rain started …

I should design a beesuit with an integrated sou’wester

… and the wind lessened, meaning the rain stayed.

And it rained for most of the afternoon.

Rain did not stop play

In the words of the late Magnus Magnusson “I’ve started, so I’ll finish”.

And it was miserable.

For the second time in two days I was soaked.

As those of you who have hunched over open hives in the rain will know, it’s your back, shoulders and hood that catch the worst of it.

This time my trousers stayed mostly dry … 

Nucs in the rain

The high point of the afternoon (and, let’s face it, the bar was pretty low) was the realisation that housing the cell raiser in the bee shed was an inspired choice.

When adding queen cells to nucs you either have to detach them in advance from the cell bar frame and keep them warm somewhere convenient, or collect them in turn.

Five gone, five to go … queen cells reared in a Ben Harden cell raiser

I had nowhere to keep them warm, so was returning to the Ben Harden setup to retrieve them one at a time. Since it was warm and dry in the shed I could leave the frame balanced (as shown above) still festooned with bees and fetch each cell as needed.

Had they been outside I would have had to stop.

It was difficult enough making up the nucs in the rain, one hand holding a frame, the other lifting the roofs on and off. 

It would have been impossible to juggle the cell raiser and cell bar frame as well.

But I eventually finished and moved half a dozen of the nucs to another apiary 16. I put the Varroa trays underneath 17, filled the feeders with syrup and opened the entrances a half inch or so to allow the bees to fly.

Half a dozen nucs, all in a row

And then I returned to the main apiary to tidy up.

And the swarm?

I still don’t know where the swarm came from 18.

I checked it between downpours. 

Despite opening the box very gently, with almost no smoke, the bees ‘balled’ the queen and killed her. I found her in the middle of a golf ball-sized clump of bees on the floor. 

Queen being ‘balled’ … it didn’t end well

After dislodging some of the bees with my fingers I found her, laying on her side, as dead as a dodo. You can just see her in the photo above., slightly below the middle of the image by the edge of the mesh.

Why did they do this?

I’ve inspected dozens of swarms the day after hiving them and don’t ever remember having this happen before.

Perhaps it was the poor weather? Maybe my ‘very gently’ wasn’t gentle enough?

The queen was unmarked and (obviously) unclipped.

To me, she looked like a virgin queen, rather than a slimmed down mated queen 19

There were two nucs in the apiary containing virgin queens. I didn’t inspect either, but a quick peek through the plastic crownboard showed both still appeared to contain bees. The size of the swarm, although small (as swarms go) looked much larger than the size of these nucs.

I’ll check again next week …

I added a queen cell to the swarm and set off for home.

Chasing the setting sun

It’s a beautiful commute, across Rannoch and through Glencoe, chasing the setting sun. 

And my trousers were finally dry 😉


Note

I’ve already grossly exceeded my self-imposed word count this week. This is not meant as a practical guide to queen rearing 20. For those interested in queen rearing – the most fun you can have with a beesuit on 21 – there are lots of articles here with the nitty gritty practicalities. Try these for starters … queen rearing, an introduction to the Ben Harden system, setup and cell raising.

No risk, no reward

“April showers bring May flowers”, or something close to that, is a poem that has its origins in the General Prologue of Chaucer’s Canterbury Tales.

It means that the Atlantic low pressure systems that roll in from the west during April, often bringing rain, also account for the abundance of flowers that bloom in May.

Not much sign of any April showers last month …

April 2021 sunshine anomaly compared to 1981 – 2010

Most of the country was bathed in spring sunshine, with Scotland and the north of England getting 150-170% of the average seen over the last 30-40 years. 

Unsurprisingly, with that amount of sunshine, rain was in short supply. Much of the country experienced only 20-33% of the usual April rainfall.

Which should be great for beekeeping, right?

Well, not if it’s accompanied by some of the lowest temperatures seen for half a century.

April 2021 average temperature anomaly compared to 1981 – 2010

The entire country was significantly colder than normal, with the bit of Fife my bees are in being 3°C colder than the average over the last decade, with frosts on ~60% of the nights during the month 1.

And, for those of us interested in queen rearing, this sort of start to the season can cause frustrating delays … or encourage a bit of risk taking.

The heady mix of strong colonies, drones and good weather

Queen rearing needs three things to occur at more or less the right time – which doesn’t mean simultaneously.

  1. The colony needs to be strong enough to rear new queens. Good queens – whether reared from grafted larvae or naturally under the swarming or emergency impulse – require lots of nurse bees in the hive to lavish the developing larvae with attention. Three or four frames of brood isn’t enough. The hive really needs to be bursting with bees. A long winter, cold spring or bad weather can hold the colony back. 
  2. Drones need to be available to mate with the virgin queens. Drones take 24 days to develop from egg to emerged adult. However, before they can mate, drones need to reach sexual maturity and learn about the environment around the hive. Sexual maturity takes 6 – 16 days and, at the same time, the drones embark on a number of orientation flights which start a week or so after emergence. 
  3. Good weather for queen mating. After emerging the queen also needs to reach sexual maturity. This takes 5-6 days. She then goes on one or more mating flights, before returning to the hive for a lifetime of egg laying 2. Bad weather – either temperatures significantly below 20°C, rain or strong winds – all prevent these mating flights from taking place. 

With no drones, a weak colony, or lousy weather there’s little chance of producing high quality, well-mated queens.

Or perhaps of producing any queens at all 🙁

Second impressions

My Fife colonies were first inspected in mid-April. Most were doing OK, with at least 5-7 frames of brood and some fresh nectar in the brood box. 

Despite the low temperatures they were making the most of the sunshine and foraging whenever possible.

A week later, at their second inspection on the 25th, the majority of colonies had 1-2 supers 3 and were building up well. All had drone brood and some had adult drones.

By this time I’d identified – from my records, the overwinter performance (stores used, strength and build-up) and their behaviour when inspected under frankly rubbish conditions – which colonies I would be using for queen rearing.

I also knew which colonies would need to be requeened.

My ‘rule of thirds’

My colony selection for stock improvement is simple and straightforward.

Colonies that I consider form the worst third of my stocks are always requeened 4. Furthermore, I do my best to avoid these bees contributing to the gene pool. I don’t use larvae from them for grafting and I don’t split them and allow them to rear their own queens 5.

Ideally (in terms of the gene pool, not in terms of their fate 🙁 ) I’d also remove all drone brood from these colonies. These drones will most likely mate with queens from other hives 6, but if their genes aren’t good enough for me they probably aren’t good enough for the unsuspecting virgin queens in the neighbourhood either.

Colonies I consider in my top one third of stocks are used as a source of larvae for grafting, and can be split and allowed to rear their own new queens.

The ‘middle’ third are requeened if I have spare queens, which I usually do.

It’s surprising how quickly this type of selection results in stock improvement. By focusing on a series of simple traits I favour (e.g. frugal with winter stores, calm when inspected in persistent rain) or dislike (e.g. running on the comb, following, stroppiness) in my bees I’ve ended up with stocks that are pretty good 7.

Queen cells … don’t panic

On April 25th many colonies had play cups but only one had charged queen cells

Considering the 10 day weather forecast, my overall level of preparedness to start queen rearing (!) and the relatively early stage of development of the cells (24-48 hour larvae) I nearly squidged the cells and closed the hive up for another week.

It still felt too early and far too cold.

know that knocking back queen cells is not swarm control (and have suggested this is engraved on all hive tools sold to beginners).

However, swarming also requires good weather. If it’s 9-11°C the colony will not swarm … and I was pretty confident that the weather wasn’t going to warm up significantly in the week until the next inspection.

So, in my typical Do as I say, don’t do as I do” style, I reckoned it was a safe bet to destroy the queen cells and check again a week later.

I would have expected to find more queen cells then, but I’d have been astounded if the colony had swarmed in the intervening period.

Second thoughts

But this was a lovely colony. 

It has always been good, had overwintered on a single 12.5 kg block of fondant and was already on 10 frames of brood in all stages 8. And that was a full box as it’s a Swienty brood box that only takes 10 National frames. To give them more room I would have had to add another brood box.

Not only that, but the bees were calm when inspected under miserable conditions. They didn’t run about on the comb and they weren’t aggressive.

The colony was comfortably near the top of my top third …

If the colony had swarmed, despite the queen being clipped, there’s a good chance I’d have lost her. The apiary is ~140 miles from home and that’s not the sort of journey you can make to ‘quickly check the hives’

So, how could I ensure that I didn’t lose the queen and take advantage of the quality of the stock and its apparent readiness to reproduce?

Plan B

Looking after the queen was straightforward. 

I prepared a 3 frame nucleus colony containing the frame the queen was on and a couple of frames of emerging brood. I added a frame of sealed stores and a new frame of foundation.

A frame of sealed stores … perfect for feeding nucs

I stuffed the entrance of the nuc with grass, wedged the frames together with a foam block and pinned a travel screen over the top.

The travel screen really wasn’t necessary. I had to transport the bees to another apiary and, although there was now weak sunshine the temperature was only just double digits (°C) and my beesuit was still damp from an earlier shower. I didn’t fancy driving for 40 minutes with the windows open to keep the bees cool, so opted to ventilate them better and keep me a bit warmer 😉

This is the nucleus method of swarm control. It’s almost foolproof 9.

It is possible to get it wrong, but you have to try quite hard. 

In my experience it’s the most dependable method and has the added advantage of using the minimal amount of additional equipment.

The queen was safe in a new box. She had space to lay and lots of young bees to support her. The queenless colony had ample stores and 7 frames of brood in all stages. 

This nucleus colony will be used as a source of larvae for grafting in mid/late May. I can easily regulate the strength of this colony – to prevent them swarming – by stealing a frame or two of brood periodically. If replaced by a foundationless frame (or a frame with foundation) they will draw lovely new comb with the help of the nectar flow from the oil seed rape.

The original, and now queenless, colony was given three new frames and closed up.

One week later

In early May the cold, sunny weather was replaced by very cold, very wet weather 🙁

On the 3rd of May I drove through snow and heavy rain to get to the apiary. The following day I started inspecting the colonies in intermittent light drizzle and a temperature of 7°C. 

Not ideal 🙁

The weather gradually improved. By the time I finished in the apiary it had reached a balmy 11°C.

Notwithstanding the conditions, the bees were well behaved. 

With some bees, if you open the hive in poor weather they rush out mob-handed.

Before you get a chance to think “Can I smell bananas?” you’ve collected half a dozen stings and they’re recruiting reinforcements 10.

You know it’s going to be a long and painful day …

However, perhaps because the bees were sick and tired of the low temperatures this spring they just sat on the comb looking mournful … you could almost see their little faces as row upon row of upside down smilies 🙁 🙁 🙁 🙁 

This ‘calmness in the face of adversity’ (!) makes these bees easy and tractable to deal with in poor conditions. It’s a byproduct of selection from the ‘best’ third of my stocks year after year.

I don’t actively select bees for bad weather beekeeping, but it’s a nice bonus when it happens.

The queenless colony now contained 7 frames of sealed brood, many of which also contained queen cells. They had almost completely drawn the new frames I’d added the previous week when I made up the nuc.

More nucs

I prepared 3 two frame nucs from the hive, leaving the remaining frames – with some new ones – in the dummied down brood box.

Doing this sort of manipulation in poor weather takes preparation and planning. You do not want to be rushing back to the shed for an extra frame, or searching around for entrance blocks, or doing anything that leaves the bees exposed for longer than necessary.

Ready to go …

The poly nucs were all set up, with the entrances sealed, a frame of capped stores, two new frames and a dummy board. The foam travel blocks (to hold the frames tightly together), plastic crownboards, lids and hive straps were piled up within easy reach.

Making up two frame nucs

All of this was done before I’d even opened the queenless hive 11.

The queen cells were all sealed (as would be expected from the timing of the last inspection, 8-9 days earlier) and had been produced in a busy hive, with lots of nurse bees to attend to them.

The majority would have been reared under the emergency impulse.

I quickly and carefully transferred two frames from the queenless hive to each nuc. I ensured that each nuc received a frame containing a good queen cell.

In practice, the nucs and the colony remnants probably all ended up with several queen cells.

Not another “Do as I say, don’t do as I do?” situation?

I usually leave only one queen cell in a hive to ensure a strong colony doesn’t produce multiple casts.

However, this time I did not thin out any of the queen cells. 

This was a pragmatic decision largely based upon the weather. It was too cold to be searching across every frame to select the best cell. The bees would have been distressed and disturbed, and there was a risk of chilling the brood 12.

It was also a rational decision considering the strength of the colonies I was setting up. With a much-reduced population of bees it’s very unlikely the colony will allow all the queens to emerge. I expect most of the cells to be torn down by the workers.

The nucs were all transferred to an apiary over three miles away. This avoids any risk of them reducing in strength due to flying bees returning to the original site.

These nucs were relatively small colonies so will require some TLC. I’ll check them soon after the new queens emerge. If they look understrength I’ll add a frame of emerging brood (harvested from one of the bottom ‘third’ of colonies. They might not be good enough to split but they are still very useful bees 🙂 ).

I’ll then leave them for at least 2-3 weeks hoping that the weather improves significantly for queen mating.

This is the ‘taking a risk’ bit of the whole process. Mid/late May should offer some suitable days for queen mating, but if this weather continues it’s not guaranteed. 

Somewhere between ~26-33 days after emergence the virgin queen becomes too old to mate successfully.

For these queens, that will take us to the week beginning the 3rd of June.

If we’ve not had any good queen mating days by then things will be getting a bit desperate 🙂

Active queen rearing begins soon

Splitting a colony into nucs containing queen cells is one way of rearing new queens. The quality of the resulting colony is dependent – at least partially – on the quality of the colony you start with.

With a high quality starting stock it is effectively ‘passive’ queen rearing … very little effort with potentially good rewards. 

What’s not to like?

Preliminary setup for Ben Harden queen rearing

But with the weather slowly but inexorably improving (really!) it’s time to start thinking about ‘active’ queen rearing – cell starters, grafting, cell finishers, mini-nucs etc.

With the good quality queen busily laying away in her nuc box it was time to set up a colony for queen rearing using the Ben Harden approach.

In this instance the quality of the colony is largely immaterial. It needs to be strong and healthy, but its genetics will not contribute to the quality of the resulting queens. 

My final task before leaving the apiary was to add the fat dummies and additional frames in preparation for queen rearing using selected grafted larvae.

And that’s what I hope to be doing next week 🙂


 

Acting on Impulse

Men just can’t help acting on Impulse … 

This was the advertising strapline that accompanied the 1982 introduction of a new ‘body mist’ perfume by Fabergé. It was accompanied by a rather cheesy 1 set of TV commercials with surprised looking (presumably fragrant) women being accosted by strange men proffering bouquets of flowers 2.

Men just can’t help acting on Impulse …

And, it turns out that women – or, more specifically, female worker honey bees – also act on impulse

In this case, these are the ‘impulses’ that result in the production of queen cells in the colony.

Understanding these impulses, and how they can be exploited for queen rearing or colony expansion (or, conversely, colony control), is a very important component of beekeeping.

The definition of the word impulse is an ‘incitement or stimulus to action’.

The action, as far as our bees are concerned, is the development of queen cells in the colony.

If we understand what factors stimulate the production of queen cells we can either mitigate those factors – so reducing the impulse and delaying queen cell production (and if you’re thinking ‘swarm prevention‘ here you’re on the right lines) – or exploit them to induce the production of queen cells for requeening or making increase.

But first, what are the impulses?

There are three impulses that result in the production of queen cells – supersedure, swarm and emergency.

Under natural conditions i.e. without pesky meddling by beekeepers, colonies usually produce queen cells under the supersedure or swarm impulse.

The three impulses are:

  1. supersedure – in which the colony rears a new queen to eventually replace the current queen in situ
  2. swarm – during colony reproduction (swarming) a number of queen cells are produced. In due course the current queen leaves heading a prime swarm. Eventually a newly emerged virgin queen remains to get mated and head the original colony. In between these events a number of swarms may also leave headed by virgin queens (so-called afterswarms or casts).
  3. emergency – if the queen is lost or damaged and the colony rendered queenless, the colony rears new queens under the emergency impulse.

Many beekeepers, and several books, state that you can determine the type of impulse that induced queen cell production by the number, appearance and location of the queen cells.

And, if you can do this, you’ll know what to do with the colony simply by judging the queen cells.

If only it were that simple

Wouldn’t it be easy?

One or two queen cells in the middle of frame in the centre of the brood nest? Definitely supersedure. Leave the colony alone and the old queen will be gently replaced over the next few weeks. Brood production will continue uninterrupted and the colony will stay together and remain productive.

A dozen or more sealed queen cells along the bottom edge of a frame? The colony is definitely  in swarm mode and – since the cells are already capped – has actually already swarmed. Time to thin out the cells and leave just one to ensure no casts are also lost.

But it isn’t that simple 🙁

Bees haven’t read the textbooks so don’t necessarily behave as expected.

I’ve found single open queen cells in the middle of a central frame, assumed it was supersedure, left the colony alone and lost a swarm from the hive a few days later 🙁

D’oh!

Or I’ve found loads of capped queen cells on the edges of multiple frames in a hive, assumed that I’d missed a swarm … only to subsequently find the original marked queen calmly laying eggs as I split the brood box up to make several nucleus colonies  🙂

Not all queen cells are ‘born’ equal

It’s worth considering what queen cells are … and what they are not. And how queen cells are started.

There are essentially two ways in which queen cells are started.

They are either built from the outset as vertically oriented cells into which the queen lays an egg, or they start their life as horizontally oriented 3 worker cells which, should the need arise, are re-engineered to face vertically.

Play cup or queen cell?

Play cup or are they planning their escape …?

Queen cells started under the supersedure or swarming impulse are initially created as ‘play cups‘. A play cup looks like a small wax version of an acorn cup – the woody cup-like structure that holds the acorn nut. In the picture above the play cup is located on the lower edge of a brood frame, but they are also often found ‘centre stage‘ in the middle of the frame.

Play cups

A colony will often produce many play cups and their presence is nothing to be concerned about. In fact, I think it’s often a rather encouraging sign that the colony is sufficiently strong and healthy that it might be thinking of raising a new queen. 

Before we leave play cups and consider how emergency queen cells start life it’s worth emphasising the differences between play cups and queen cells.

Play cups are not the same as queen cells

Until a play cup is occupied by an egg it is not a queen cell.

At least it’s not as far as I’m concerned 😉

And, even if it contains an egg there’s no guarantee it will be supported by the workers to develop into a new queen 4.

However, once the cell contains a larva and it is being fed by the nurse bees – evidenced by the larva sitting in an increasingly thick bed of royal jelly – then it is indisputably a queen cell.

Charged queen cell ...

Charged queen cell …

And to emphasise the fundamental importance in terms of colony management I usually refer to this type of queen cell as a ‘charged queen cell’.

Once charged queen cells appear in the colony, all other things being equal, they will be maintained by the workers, capped and – on the 16th day after the egg was laid – will emerge as a new queen.

And it is once charged queen cells are found in the colony that swarm control should be considered 5.

But let’s complete our description of the queen cells by considering those that are produced in response to the emergency impulse.

Emergency queen cells

Queen cells produced under the emergency impulse differ from those made under the swarm or supersedure impulse. These are the cells that are produced when the colony is – for whatever reason – suddenly made queenless. 

Without hamfisted beekeeping it’s difficult to imagine or contrive a scenario under which this would occur naturally 6, but let’s not worry about that for the moment 7

The point is that, should a colony become queenless, the workers in the colony can select one or more young larvae already present in worker cells and rear them as new queens.

So, although the eggs are (obviously!) laid by the queen 8, they have been laid in a normal worker cell. To ensure that they get lavished with attention by the nurse bees, feeding them a diet enriched in Royal Jelly, the cell must be re-engineered to project vertically downwards.

Location, location

Queen cells can occur anywhere in the hive to which the queen has access.

Queen cell on excluder

Queen cell on underside of the excluder …

But they are most usually found on the periphery of the frame, either along the lower edge …

Queen cells ...

Queen cells …

… or a vertical side edge of the frame …

Sealed queen cells

… but they can also be found slap, bang in the middle of a brood frame.

Single queen cell in the centre of a frame

And remember that bees have a remarkable ability to hide queen cells in inaccessible nooks and crannies on the frame … and that finding any queen cells is much more difficult when the frame is covered with a wriggling mass of worker bees.

Location and impulses

Does the location tell us anything about the impulse under which the bees generated the queen cell?

Probably not, or at least not reliably enough that additional checks aren’t also needed 🙁

Many descriptions will state that a small number (typically 1-3) of queen cells occupying the centre of a frame are probably supersedure cells. 

Whilst this is undoubtedly sometimes or even often true, it is not invariably the case.

The workers choose which larvae to rear as queens under the emergency impulse. If the only larvae of a suitable age are situated mid-frame then those are the ones they will choose.

In addition, since generating emergency cells requires re-engineering worker cells, newer comb is likely more easily manipulated by the workers.

Some beekeepers ‘notch’ comb under suitably aged larvae to induce queen cell production at particular sites on the frame 9. The photograph shows a frame of eggs with a notch created with the hive tool. It’s better to place the notch underneath suitably aged larvae, not eggs. Clearly, the age of the larvae is more critical than the ease with which the comb can be reworked. Those who use this method [PDF] properly/extensively claim up to a 70% ‘success’ rate in inducing queen cell placement on the frame. This can be very useful if the plan is to cut the – well separated – queen cells out and use them in mating nucs or for requeening other colonies.

Eggs in new comb ...

Eggs in new comb …

Comb at the bottom or side edges of the frame often has space adjacent and underneath it. Therefore the bees might favour these over sites mid-frame (assuming ample suitable aged larvae) simply because the comb is easier to re-work in these locations.

And don’t forget … under the emergency impulse the colony preferentially chooses the rarest patrilines to rear as new queens 10.

Not all larvae are equal, at least when rearing queens under an emergency impulse.

Active queen rearing and the three impulses

By ‘active’ queen rearing I mean one of the hundreds of methods in which the beekeeper is actively involved in selecting the larvae from which a batch of new queens are reared.

This doesn’t necessarily mean grafting , towering cell builders and serried rows of Apidea mini nucs.

It could be as simple as taking a queen out of a good colony to create a small nuc and then letting the original colony generate a number of queen cells.

Almost all queen rearing methods use either the emergency or supersedure impulses to induce new queen cell production 11.

For example, let’s consider the situation described above.

Active queen rearing and the emergency impulse

A strong colony with desirable traits (calm, productive, prolific … choose any three 😉 ) is made queenless by removing the queen on a frame of emerging brood into a 5 frame nucleus hive. With a frame of stores and a little TLC 12 the queen will continue to lay and the nuc colony will expand.

Everynuc

Everynuc …

But the, now queenless, hive will – under the emergency impulse – generate a number of new queen cells. These will probably be distributed on several frames if the queen was laying well before she was removed.

The colony will select larvae less than ~36 hours old (i.e. less than 5 days since the egg was laid) for feeding up as new queens.

If the beekeeper returns to the hive 8-9 days later it can be split into several 5 frame nucs, each containing a suitable queen cell and sufficient emerging and adherent bees to maintain the newly created nucleus colony 13.

Active queen rearing and the supersedure impulse

In contrast, queenright queen rearing methods such as the Ben Harden system exploit the supersedure impulse.

Queen rearing using the Ben Harden system

In this method suitably aged larvae are offered to the colony above the queen excluder. With reduced levels of queen pheromones present – due to the physical distance and the fact that queen cannot leave a trail of her footprint pheromone across the combs above the QE – the larvae are consequently raised under the supersedure impulse.

Capped queen cells

Capped queen cells produced using the Ben Harden queenright queen rearing system

I’m always (pleasantly) surprised this works so well. Queen cells can be produced just a few inches away from a brood box containing a laying queen, with the workers able to move freely through the queen excluder. 

Combining impulses …

Finally, methods that use Cloake or Morris boards 14 use a combination of the emergency and supersedure impulses.

Cloake board ...

Cloake board …

In these methods the colony is rendered transiently queenless to start new queen cells. About 24 hours later the queenright status is restored so that cells are ‘finished’ under the supersedure response.

The odd one out, as it’s not really practical to use it for active queen rearing, is the swarming impulse. Presumably this is because the conditions used to induce swarming are inevitably rather difficult to control. Active queen rearing is all about control. You generally want to determine the source of the larvae used and the timing with which the queen cells become available.

Environmental conditions can also influence colonies on the brink of swarming … literally a case of rain stopping play.

Acting on impulse

If there are play cups in the colony then you don’t need to take any action 15, but if there are charged queen cells present then your bees are trying to tell you something.

Precisely what they’re trying to tell you depends upon the number and position of the queen cells, the state or appearance of those cells, and the state of the colony – whether queenright or not.

What you cannot do 16 is decide what action to take based solely on the number, appearance or position of the queen cells you find in the colony. 

Is the colony queenright?

Are there eggs present in the comb?

Does the colony appear depleted of bees?

If there are lots of sealed queen cells, no eggs, no sign of the queen and a depleted number of foragers then the colony has probably swarmed. 

Frankly, this is pretty obvious, though it’s surprising the number of beekeepers who cannot determine whether their colony has swarmed or not.

But other situations are less clear … 

If there are a small number of charged queen cells, eggs, a queen and a good number of bees in the hive then it might be supersedure.

Or the colony might swarm on the day the first cell is sealed 🙁

How do you distinguish between these two situations? 

Is it mid-May or mid-September? Swarming is more likely earlier in the season, whilst supersedure generally occurs later in the season.

But not always 😉

Is the queen ‘slimmed down’ and laying at a reduced rate?

Much trickier to determine … but if she is then they are likely to swarm.

Decisions, decisions 😉 … and going by the number of visits to my previous post entitled Queen cells … don’t panic! there are lots of beekeepers trying to make these decisions right now 🙂


 

Brexit and beekeeping

The ‘oven ready’ deal the government struck with the EU in the dying hours of 2020 was a bit less à la carte and a bit more table d’hôte.

The worst of the predictions of empty supermarket shelves and the conversion of Essex into a 3500 km2 lorry park have not materialised 1.

But there are other things that haven’t or won’t appear.

And one of those things is bees.

Bee imports

There is a long history of bee imports into the UK, dating back at least a century. In recent years the number of imports has markedly increased, at least partially reflecting the increasing popularity of beekeeping. 

Going up! Imports of queens, nucs and packages to the UK, 2007-2020 (National Bee Unit data)

Queens are imported in cages, usually with a few attendant workers to keep them company. Nucs are small sized colonies, containing a queen, bees and brood on frames. 

Packages are the ‘new kid on the block’ (in the UK) with up to 2500 per year being imported after 2013. Packages are queenless boxes of bees, containing no frames or brood.

Empty boxes after installing packages of bees

They are usually supplied in a mesh-sided box together with a queen. The bees are placed into a hive with frames of foundation and the queen is added in an introduction cage. They are fed with a gallon to two of syrup to encourage them to draw comb.

Installing a package of bees

It’s a very convenient way to purchase bees and avoids at least some of the risk of importing diseases 2. It’s also less expensive. This presumably reflects both the absence of frame/foundation and the need for a box to contain the frames.

But, post-Brexit, importation of packages or nucs from EU countries is no longer allowed. You are also not allowed to import full colonies (small numbers of these were imported each year, but insufficient to justify adding them to the graph above).

Queen imports are still allowed.

Why are were so many bees imported?

The simple answer is ‘demand’.

Bees can be reared inexpensively in warmer climates, such as southern Italy or Greece. The earlier start to the season in these regions means that queens, nucs or packages can be ready in March to meet the early season demand by UK beekeepers.

If you want a nuc with a laying queen in March or April in the UK you have two choices; a) buy imported bees, or b) prepare or purchase an overwintered nuc.

I don’t have data for the month by month breakdown of queen imports. I suspect many of these are also to meet the early season demand, either by adding them to an imported package (see above) or for adding to workers/brood reared and overwintered in a UK hive that’s split early in the season to create nucleus colonies.

Some importers would sell the latter on as ‘locally reared bees’. They are … sort of. Except for the queen who of course determines the properties of all the bees in the subsequent brood 🙁

An example of being “economical with the truth” perhaps?

Imported queens were also available throughout the season to replace those lost for any number of reasons (swarming, poor mating, failed supersedure, DLQ’s, or – my speciality – ham-fisted beekeeping) or to make increase.

And to put these imports into numerical context … there are about 45,000 ‘hobby’ beekeepers in the UK and perhaps 200+ bee farmers. Of the ~250,000 hives in the UK, about 40,000 are managed by bee farmers.

What are the likely consequences of the import ban?

I think there are likely to be at least four consequences from the ban on the importation of nucs and packages to the UK from the EU:

  1. Early season nucs (whatever the source) will be more expensive than in previous years. At the very least there will be a shortfall of ~2000 nucs or packages. Assuming demand remains the same – and there seems no reason that it won’t, and a realistic chance that it will actually increase – then this will push up the price of overwintered nucs, and the price of nucs assembled from an imported queen and some ‘local’ bees. I’ve seen lots of nucs offered in the £250-300 range already this year.
  2. An increase in imports from New Zealand. KBS (and perhaps others) have imported New Zealand queens for several years. If economically viable this trade could increase 3.
  3. Some importers may try and bypass the ban by importing to Northern Ireland, ‘staging’ the bees there and then importing them onwards to the UK. The legality of this appears dubious, though the fact it was being considered reflects that this part of the ‘oven ready’ Brexit deal was not even table d’hôte and more like good old-fashioned fudge.
  4. Potentially, a post-Covid increase in bee smuggling. This has probably always gone on in a limited way. Presumably, with contacts in France or Italy, it would be easy enough to smuggle across a couple of nucs in the boot of the car. However, with increased border checks and potential delays, I (thankfully) don’t see a way that this could be economically viable on a large scale.

Is that all?

There may be other consequences, but those are the ones that first came to mind.

Of the four, I expect #1 is a nailed-on certainty, #2 is a possibility, #3 is an outside possibility but is already banned under the terms of the Northern Ireland Protocol which specifically prohibits using Northern Ireland as a backdoor from Europe, and #4 happens and will continue, but is small-scale.

Of course, some, all or none of this ban may be revised as the EU and UK continue to wrangle over the details of the post-Withdrawal Agreement. Even as I write this the UK has extended the grace period for Irish sea border checks (or ‘broken international law’ according to the EU). 

This website is supposed to be a politics-free zone 4 … so let’s get back to safer territory.

Why is early season demand so high?

It seems likely that there are three reasons for this early season demand:

  1. Commercial beekeepers needing to increase colony numbers to provide pollination services or for honey production. Despite commercials comprising only ~0.4% of UK beekeepers, they manage ~16% of UK hives. On average a commercial operation runs 200 hives in comparison to less than 5 for hobby beekeepers. For some, their business model may have relied upon the (relatively) inexpensive supply of early-season bees.
  2. Replacing winter losses by either commercial or amateur beekeepers. The three hives you had in the autumn have been slashed to one, through poor Varroa management, lousy queen mating or a flood of biblical proportions. With just one remaining hive you need lots of things to go right to repopulate your apiary. Or you could just buy them in.
  3. New beekeepers, desperate to start beekeeping after attending training courses through the long, dark, cold, wet winter. And who can blame them? 

For the rest of the post I’m going to focus on amateur or hobby beekeeping. I don’t know enough about how commercial operations work. Whilst I have considerable sympathy if this change in the law prevents bee farmers fulfilling pollination or honey production contracts, I also question how sensible it is to depend upon imports as the UK extricates itself from the European Union.

Whatever arrangement we finally reached it was always going to be somewhere in between the Armageddon predicted by ‘Project Fear’ and the ‘Unicorns and sunlit uplands’ promised by the Brexiteers.

Where are those sunlit uplands?

And that had been obvious for years.

I have less sympathy for those who sell on imported bees to meet demand from existing or new beekeepers. This is because I think beekeeping (at least at the hobbyist level) can, and should, be sustainable.

Sustainable beekeeping

I would define sustainable beekeeping as the self-sufficiency that is achieved by:

  • Managing your stocks in a way to minimise winter losses
  • Rearing queens during the season to requeen your own colonies when needed (because colonies with young queens produce brood later into the autumn, so maximising winter bee production) and to …
  • Overwinter nucleus colonies to make up for any winter losses, or for sale in the following spring

All of these things make sound economic sense. 

More importantly, I think achieving this level of self-sufficiency involves learning a few basic skills as a beekeeper that not only improve your beekeeping but are also interesting and enjoyable.

I’ve previously discussed the Goldilocks Principle and beekeeping, the optimum number of colonies to keep considering your interest and enthusiasm for bees and the time you have available for your beekeeping.

It’s somewhere between 2 and a very large number. 

For me, it’s a dozen or so, though for years I’ve run up to double that number for our research, and for spares, and because I’ve reached the point where it’s easy to generate more colonies (and because I’m a lousy judge of the limited time I have available 🙁 ).

Two is better than one, because one colony can dwindle, can misbehave or can go awry, and without a colony to compare it with you might be none the wiser that nothing is wrong. Two colonies also means you can always use larvae from one to rescue the other if it goes queenless.

And with just two colonies you can easily practise sustainable beekeeping. You are no longer dependent on an importer having a £30 mass-produced queen spare.

What’s wrong with imported bees?

The usual reason given by beekeepers opposed to imports is the risk of also importing pathogens.

Varroa is cited as an example of what has happened. 

Tropilaelaps or small hive beetle are given as reasons for what might happen.

And then there are usually some vague statements about ‘viruses’. 

There’s good scientific evidence that the current global distribution of DWV is a result of beekeepers moving colonies about.

More recently, we have collaborated on a study that has demonstrated an association between honey bee queen imports and outbreaks of chronic bee paralysis virus (CBPV). An important point to emphasise here is that the direction of CBPV transmission is not yet clear from our studies. The imported queens might be bringing CBPV in with them. Alternatively, the ‘clean’ imported queens (and their progeny) may be very susceptible to CBPV circulating in ‘dirty’ UK bees. Time will tell.

However, whilst the international trade in plants and animals has regularly, albeit inadvertently, introduced devastating diseases e.g. Hymenoscyphus fraxineus (ash dieback), I think there are two even more compelling reasons why importation of bees is detrimental.

  1. Local bees are better adapted to the environment in which they were reared and consequently have increased overwintering success rates.
  2. I believe that inexpensive imported bees are detrimental to the quality of UK beekeeping.

I’ve discussed both these topics previously. However, I intend to return to them again this year. This is partly because in this brave new post-Brexit world we now inhabit the landscape has changed.

At least some imports are no longer allowed. The price of nucs will increase. Some/many of these available early in the season will be thrown together from overwintered UK colonies and an imported queen.

These are not local bees and they will not provide the benefits that local bees should bring.

Bad beekeeping and bee imports

If imported queens cost £500 each 5 there would be hundreds of reasons to learn how to rear your own queens. 

But most beekeepers don’t …

Although many beekeepers practise ‘passive’ queen rearing e.g. during swarm control, it offers little flexibility or opportunity to rear queens outside the normal swarming season, or to improve your stocks.

In contrast, ‘active’ queen rearing i.e. selection of the best colonies to rear several queens from, is probably practised by less than 20% of beekeepers.

This does not need to involve grafting, instrumental insemination or rows of brightly coloured mini-nucs. It does not need any large financial outlay, or huge numbers of colonies to start with.

But it does need attention to detail, an understanding of – or a willingness to learn – the development cycle of queens, and an ability to judge the qualities of your bees.

Essentially what it involves is slightly better beekeeping.

But, the availability of Italian, Greek or Maltese queens for £20 each acts as a disincentive.

Why learn all that difficult ‘stuff’ if you can simply enter your credit card details and wait for the postie?

Overwintering 5 frame poly nuc

Overwintering 5 frame poly nuc

And similar arguments apply to overwintering nucleus colonies. This requires careful judgement of colony strength through late summer, and the weight of the nuc over the winter.

It’s not rocket science or brain surgery or Fermat’s Last Theorem … but it does require a little application and attention.

But, why bother if you can simply wield your “flexible friend” 6 in March and replace any lost colonies with imported packages for £125 each?

Rant over

Actually, it wasn’t really a rant. 

My own beekeeping has been sustainable for a decade. I’ve bought in queens or nucs of dark native or near-native bees from specialist UK breeders a few times. I have used these to improve my stocks and sold or gifted spare/excess nucs to beginners.

I’ve caught a lot of swarms in bait hives and used the best to improve my bees, and the remainder to strengthen other colonies.

The photographs of packages (above) are of colonies we have used for relatively short-term scientific research. 

I’m going to be doing a lot of queen rearing this season. Assuming that goes well, I then expect to overwinter more nucs than usual next winter. 

I then hope that the bee import ban remains in place for long enough until I can sell all these nucs for an obscene profit which I will use to purchase a queen rearing operation in Malta. 😉

And I’m going to write about it here.


Notes

BBKA statement made a day or two after this post appeared. The BBKA and other national associations are concerned about the potential import of Small Hive Beetle (SHB) into the UK via Northern Ireland. Whilst I still think this breaches the Northern Ireland Protocol, it doesn’t mean it won’t be attempted (and there’s at least one importer offering bees via this route). It’s not clear that the NI authorities have the manpower to inspect thousands of packages.

It’s worth noting that SHB was introduced to southern Italy in 2014 and remains established there. The most recent epidemiological report shows that it was detected as late as October 2020 in sentinel apiaries and is also established in natural colonies.

With a single exception – see below – every country into which SHB has been imported has failed to eradicate it. As I wrote in November 2014:

“Once here it is unlikely that we will be able to eradicate SHB. The USA failed, Hawaii failed, Australia failed, Canada failed and it looks almost certain that Italy has failed.”

And Italy has failed.

The one exception was a single import to a single apiary in the Portugal. Notably, the illegal import was of queens, not nucs or packages. Eradication involved the destruction of the colonies, the ploughing up of the apiary and the entire area being drenched in insecticide.

The Beekeepers Quarterly

This post also appeared in the summer 2021 edition of The Beekeepers Quarterly published by Northern Bee Books.

A New Year, a new start

The short winter days and long dark nights provide ample opportunity to think about the season just gone, and the season ahead.

You can fret about what went wrong and invent a cunning plan to avoid repetition in the future.

Or, if things went right, you can marvel at your prescience and draft the first couple of chapters of your book “Zen and the Art of Beekeeping”.

But you should also prepare for the normal events you expect in the season ahead.

In many ways this year 1 will be the same as last year. Spring build-up, swarming and the spring honey crop, a dearth of nectar in June, summer honey, miticides and feeding … then winter.

Same as it ever was as David Byrne said.

That, or a pretty close approximation, will be true whether you live in Penzance (50.1°N) or Thurso (58.5°N).

Geographical elasticity

Of course, the timing of these events will differ depending upon the climate and the weather.

For convenience let’s assume the beekeeping season is the period when the average daytime temperature is above 10°C 2. That being the case, the beekeeping season in Penzance is about 6 months long.

In contrast, in Thurso it’s only about 4 months long.

More or less the same things happen except they’re squeezed into one third less time.

Once you have lived in an area for a few years you become attuned to this cycle of the seasons. Sure, the weather in individual years – a cold spring, an Indian summer – creates variation, but you begin to expect when particular things are likely to happen.

There’s an important lesson here. Beekeeping is an overtly local activity. It’s influenced by the climate, by the weather in an individual year, and by the regional environment. You need to appreciate these three things to understand what’s likely to happen when.

OSR ... can you believe it?!

Late April 2016, Fife … OSR and snow

Events are delayed by a cold spring, but if there’s oil seed rape in your locality the bees might be able to exploit the bounteous nectar and pollen in mid-April.

Mid-April 2014, Warwickshire

Foraging might extend into October in an Indian summer and those who live near moorland probably have heather yielding until mid/late September.

Move on

You cannot make decisions based on the calendar.

In this internet-connected age I think this is one of the most difficult things for beginners to appreciate. How many times do you see questions about the timing of key events in the beekeeping season – adding supers, splitting colonies, broodlessness – with no reference to where the person asking, or answering, the question lives?

It often takes a move to appreciate this geographical elasticity of the seasons at different latitudes.

When I moved from the Midlands to Scotland 3 in 2015 I became acutely aware of these differences in the beekeeping season.

When queen rearing in the Midlands my records show that I would sometimes start grafting in the second week in April. In some years I was still queen rearing in late August, with queens being successfully mated in September.

Locally bred queen ...

Locally bred queen …

In the last 5 years in Scotland the earliest I’ve seen a swarm was the 30th of April and the latest I’ve had one arrive in a bait hive was mid-July. Here, queen rearing is largely restricted to mid-May to late-June 4.

All of this is particularly relevant as most of my beekeeping is moving from the east coast to the west coast of Scotland this year.

I’m winding down my beekeeping in Fife and starting afresh on the west coast.

The latitude is broadly the same, but the local environment is very different.

And so are the bees … which means there are some major changes being planned.

What are local bees?

I’m convinced about the benefits of local bees. The science – which I’ve discussed in several previous posts – shows that locally-reared bees are physiologically adapted to their environment and both overwinter and survive better.

But what is local?

Does it mean within a defined geographical area?

If so, what is the limit?

Five miles?

Fifty miles?

What is local? Click to enlarge and read full legend.

I think that’s an overly simplistic approach.

The Angus glens are reasonably ‘local’ to me. Close enough to go for an afternoon walk, or a summer picnic. They’re less than 40 miles north as the bee flies 5.

However, they’re a fundamentally different environment from my Fife apiaries. The latter are in intensively farmed, low lying, arable land. In Fife there’s ample oil seed rape in Spring, field beans in summer and (though not as much as I’d like) lime trees, clover and lots of hedgerows.

The Angus glens

But the Angus glens are open moorland. There’s precious little forage early in the season, but ample heather in August and September. It’s also appreciably colder in the hills due to the altitude 6.

I don’t think you could keep bees on the Angus hills all year round. I’m not suggesting you could. What I’m trying to emphasise is that the environment can be dramatically different only a relatively short distance away.

My bees

I don’t name my queens 7 but I’m still very fond of my bees. I enjoy working with them and try and help them – by managing diseases, by providing space or additional food – when needed.

I’ve also spent at least a decade trying to improve them.

Every year I replace queens heading colonies with undesirable traits like running on the comb or aggression or chalkbrood. I use my best stocks to rear queen from and, over the years, they’ve gradually improved.

They’re not perfect, but they are more than adequate.

When I moved from the Midlands to Scotland I brought my bees with me.

Forgot the scythe

Delivering bees from the Midlands to Fife

I ‘imported’ about a dozen colonies, driving them up overnight in an overloaded Transit van. The van was so full of hive stands, empty (and full) beehives and nucs that I had a full hive strapped down in the passenger seat. Fortunately the trip went without a hitch (or an emergency stop 🙂 ).

Passenger hive

Passenger hive

They certainly were not ‘local’ but I’d invested time in them and didn’t want to have to start again from scratch. In addition, some hives were for work and it was important we could start research with minimum delay.

But I cannot take any of my bees to the west coast 🙁

Treatment Varroa free

Parts of the remote north and west coast of Scotland remain free of Varroa. This includes some of the islands, isolated valleys in mountainous areas and some of the most westerly parts of the mainland.

It also includes the area (Ardnamurchan) where I live.

Just imagine the benefits of not having to struggle with Varroa and viruses every season 🙂

Although I don’t feel as though I struggle with managing Varroa, I am aware that it’s a very significant consideration during the season. I know when and how to treat to maintain very, very low mite levels, but doing so takes time and effort.

It would certainly be preferable to not have to manage Varroa; not by simply ignoring the problem, but by not having any of the little b’stards there in the first place 😉

Which explains why my bees cannot come with me 8. Once Varroa is in an area I do not think it can be eradicated without also eradicating the bees.

A green thought in a green shade … Varroa-free bees on the west coast of Scotland

I’ve already got Varroa-free bees on the west coast, sourced from Colonsay.

Is Colonsay ‘local’?

Probably. I’d certainly argue that it’s more ‘local’ to Ardnamurchan than the Angus glens are to Fife, despite the distance (~40 miles) being almost identical. Both are at sea level, with a similar mild, windy and sometimes wet, climate.

Sometimes, in the case of Ardnamurchan, very wet 🙁

My cunning plans

Although the season ahead might be “same as it ever was”, the beekeeping certainly won’t be.

My priorities are to wind down my Fife beekeeping activities (with the exception of a few research colonies we will need until mid/late 2022) and to expand my beekeeping on the west coast.

Conveniently, because it’s something I enjoy and also because it’s not featured very much on these pages recently, these plans involve lots of queen rearing.

Queen rearing using the Ben Harden system

In Fife I’m intending to split my colonies to produce nucs for sale. I’ll probably do this by sacrificing the summer honey crop. It’s easier to rear queens in late May/June and the nucs that are produced can be sold in 2021, or overwintered for sale the following season.

If I leave the queen rearing until later in the summer I would be risking either poor weather for queen mating, or have insufficient time to ensure the nucs were strong enough to overwinter.

It’s easier (and preferable) to hold a nuc back by removing brood and bees than it is to mollycoddle a weak nuc through the winter.

And on the west coast I’ll also be queen rearing with the intention of expanding my colonies from two to about eight. In this case the goal will be to start as early as possible with the aim of overwintering full colonies, not nucs. However, I’ve no experience of the timing of spring build up or swarming on the west coast, so I’ve got a lot to learn.

Something old, something new

I favour queen rearing in queenright colonies. This isn’t the place to spend ages discussing why. It suits the scale of my beekeeping, the colonies are easy to manage and it is not too resource intensive.

I’ve written quite a bit about the Ben Harden system. I have used this for several years with considerable success and expect to do so again.

I’ve also used a Cloake board very successfully. This differs from the Ben Harden system in temporarily rendering the hive queenless using a bee-proof slide and upper entrance.

Cloake board ...

Cloake board …

Using a Cloake board the queen cells are started under the emergency response, but finished in a queenright hive. It’s a simple and elegant approach. In addition, the queen rearing colony can be split into half a dozen nucs for queen mating, meaning the entire thing can be managed starting with a single double brood colony.

One notable feature of the Cloake board is that the queen cells are raised in a full-sized upper brood box. During the preparation of the hive this upper box becomes packed with bees 9. This means there are lots of bees present for queen rearing.

Concentrating the bees ...

Concentrating the bees …

It’s definitely a case of “the more the merrier” … and, considering the size of my colonies, I’m pretty certain I can achieve even greater concentrations of bees using a Morris board.

A Morris board is very similar to a Cloake board except the upper face has two independent halves. It’s used with a divided brood box (or two 5 frame nucleus boxes) and can generate sequential rounds of queen cells. I understand the principle, but it’ll be a new method I’ve not used before.

Since the bees are concentrated into half the volume it should be possible to get very high densities of bees using a Morris board.

And since I like building things for beekeeping 10, that’s what I’m currently making …

Which explains why I’ve got bits of aluminium arriving in the post, chopped up queen excluders on my workbench and Elastoplast on three fingers of my left hand 🙁

Happy New Year!


Notes

I’m rationalising my beekeeping equipment prior to moving. I have far too much! Items surplus to requirements – currently mainly flat-pack National broods and supers – will be listed on my ‘For Sale‘ page.

 

Long distance beekeeping

This post was originally entitled ‘lockdown beekeeping’. I changed it in the hope that, at some point in the future, we’ve all forgotten lockdown and are back to the ‘old normal‘. Instead, long distance beekeeping, better summarises the topic and might rank better in future Google searches …

But before I start, here’s some general advice …

Don’t do as I do, do as I say (elsewhere on this site 😉 )

I don’t think what I’m going to describe below was anything like ideal. In the end it worked out pretty well, but probably as much from luck as judgement. I’d do it again if I had to, but I’d prefer not to. I don’t think it is a workable solution for effective beekeeping in anything other than exceptional circumstances.

But 2020 has been an exceptional circumstance …

Mid-March madness

It was abundantly clear in very early March that a lockdown was inevitable 1 to restrict the spread of Covid-19. All the numbers were going in the wrong direction and other countries were already imposing quite draconian restrictions to control virus transmission 2.

I had speaking engagements with Oban & District BKA on the 12th and at the SNHBS event at Kinross on the 14th and, on the following day, I disappeared to my bolthole on the remote west coast of Scotland. 

The wild west

I decided to simply abandon the bees in Fife for at least a month while the country came to terms with movement restrictions, supermarket food deliveries, protecting the NHS and ‘working from home’.

On the day I left I checked that colonies were not too light, that the entrances were clear and that the roofs were secure and everything was strapped down.

March is too early to do anything with bees in Fife and my first inspections are usually not until mid/late April in a normal year, and even early May if there’s been a cold Spring. I therefore had a month to plan for the season ahead, with the expectation that I would have to manage the bees with the minimum possible number of visits for the next few months.

Planning

The beekeeping season contains a number of ‘moveable fixtures’.

By that I mean that certain things happen every season, but the time when they happen is not fixed. The timing depends upon the weather which, in turn, influences forage availability. It depends upon the strength of the colony, the location of the apiary and – for all I know – the phase of the moon.

Warm springs can lead to swarming by the end of April. Conversely, cold springs delay events. Dry summers generally put paid to the lime nectar and a protracted June gap can leave colonies starving in the middle of the season.

In the previous post I called these moveable fixtures the unknown knowns.

The variable timing of these moveable fixtures influences colony management by the beekeeper; this includes the spring honey harvest, swarm control and the summer honey harvest. In addition, it includes more mundane things like comb exchange, feeding the colony up for winter and Varroa management.

Bees and beekeeping are influenced by the environment, not the calendar 3.

The UK government imposed a nationwide lockdown on the 23rd of March 2020. Movement restrictions were imposed, including the distance you could travel from where you live.

Exemptions were made for allowed activities and, after lobbying from national associations and others, beekeeping was included as an exempt activity. Notwithstanding this, it was not going to be practical to conduct the usual weekly inspections from April until late July.

First inspections

I returned to Fife to conduct the first inspections in the third week of April. The spring was well advanced and the strong colonies were really booming. The overwintered nucs had built loads of brace comb in the space over the top bars and urgently needed to be moved to a full hive.

Overwintered nuc with brace comb

There were about 20 colonies spread between my two main apiaries. All were checked for space/strength, temper and the presence of a laying, marked and clipped queen 4. I didn’t have time to mollycoddle any weak colonies so these (having checked they were healthy) were united with nearby strong colonies.

Safely back in the hive

In addition, I didn’t have the luxury of time to see if poorly behaved colonies might pick up later in the season. To be frank, I had more colonies than I needed (or could easily cope with). With the need for swarm control looming, I decided to reduce colony numbers by uniting de-queened aggressive colonies with others in the same apiary. There were only a couple of these (identified the previous season and seemingly unimproved after the winter) … but every little bit helps.

United colonies, three supers, strapped up well … 25th April 2020

Finally, with the oil seed rape about to flower, I added three supers to the majority of the colonies. In a normal season these would have been added incrementally as needed. This year I had to assume (or hope) they might need them.

Swarm control

On my return to the west coast the spring was warming up. The primroses were looking fantastic and we had several weeks of outstanding weather.

Primroses – late April 2020

I enjoyed the good weather and spent the time fretting about the timing of swarm control.

My colonies tend to make swarm preparations between mid-May and the first week of June – a good example of a moveable fixture.

A priority this year was not to lose any swarms.

I did not want to inconvenience other beekeepers (or civilians’ 5) with swarms I managed to lose by ineptly doing my beekeeping from the other side of the country.

With most people trying to keep themselves isolated, 30,000 bees moving into a chimney would be a lot more than unwelcome.

Even in a normal year I do my very best not to lose swarms, and this was anything but a normal year.

I therefore decided to conduct pre-emptive swarm control on every colony in the third week of May. ‘Pre-emptive’ meaning that, whether the colonies showed any signs of swarming or not, I’d remove the queen and let them rear another.

Colonies do not swarm every year. Every now and again a strong colony of mine will show no inclination to swarm. These are great … I just pile another super or two on top and am thankful not to have to intervene.

However, strong colonies are more than likely to swarm and I didn’t feel I had the luxury of waiting around to find which wanted to and which didn’t.

A swarm in May (and how I avoided it … )

With the exception of a couple of our research colonies that seemed to be on a ‘go slow’ I treated all my colonies in the same way.

I used the nucleus method of swarm control. I removed the queen and one frame of emerging brood and put them into a 5 frame nuc box with a frame of foundation or drawn comb and a frame of stores. To ensure there were sufficient bees in the box I then shook in another frame of bees before sealing them up for transport.

All the nucs were moved to distant apiaries so there was no risk of bee numbers being depleted as they returned to the original hive.

And then there were three … nucs for pre-emptive swarm control

The parental colonies were left for 6 days and then checked for queen cells.

Ideally this should have been 7 days. By this time there would be no larvae young enough to generate additional queen cells from. However, there was a large storm moving in from the west and it was clear that there would be no possibility of doing any beekeeping while it moved through.

I therefore checked on the sixth day, knocked back all the queen cells, leaving just one good one, and then scarpered back to the west coast (meeting the storm en route).

However, before I disappeared I also checked all the nucs. All were doing fine. There was a good nectar flow and they had already drawn and laid up the frame out I’d given them. I therefore added two foundationless frames flanking the central frame. With frames either side these are usually drawn straight and true.

New comb with queen already laying it up

If you give the bees lots of foundationless frames together, particularly if the hive isn’t perfectly level, they will often make a real mess of drawing the comb out. By interleaving the new frames with those that were already drawn the bees are forced to maintain the required bee space on either side, so usually draw the frame out satisfactorily.

Getting the timing right … at least partly

When I left Fife on the 22nd of May the OSR was in full flower. It would finish sometime in early June.

My next dilemma was to time the following visit for the spring honey harvest. Too soon and the frames wouldn’t be capped. Too late and, being OSR, it might start to crystallise in the comb.

But I also wanted to deal with all the requeening colonies during the same visit and all of the nucs.

I’ve previously discussed the time it takes for a new queen to develop, emerge, mature, mate and start laying. It always takes longer than you’d like. The absolute minimum time is about two weeks, but it usually takes longer. Ideally I wanted to go through all the requeening colonies, find, mark and clip the queens or re-unite (with the nuc) those that had failed.

At the same time, with a strong nectar flow and a strongly laying queen, there was a real risk that the nucs were going to get overcrowded very fast. The longer they were left, the more chance that they would think about swarming.

I employed a number of local spies (beekeeping friends in the area) and queried them repeatedly 6 about the state of the OSR. Shortly after it finished, I returned to take off the spring honey.

A minor catastrophe

It was the 10th of June; this was exactly 20 days since leaving the requeening colonies with a single freshly-sealed queen cell.

I’ve previously mentioned that one of my apiaries is rather exposed to strong westerlies. Despite the wind-reduction netting and the rapidly growing willow hedge, this apiary had been really hammered by the storm on the 22nd/23rd of May.

Nuked nucs

Two nucs had lost their lids and crownboards and a full strapped-up hive had been blown over, denting the fence on its descent but remaining more or less intact.

How is the queen supposed to find the entrance?

The apiary hadn’t been checked since my last visit, so I’m assuming the damage happened during the storm in late May. That being the case, the nucs would have been open to the elements for about 18 days. Amazingly, both still contained laying queens and – despite looking a little the worse for wear – eventually recovered.

In contrast, the strapped up hive was not ‘open to the elements’. It had fallen entrance-first onto the ground. I think a few bees could fly from a gap where the ground didn’t quite block the entrance, but I was more concerned about getting them upright again to check too carefully.

Despite my best efforts I failed to find a queen in this hive. My frames are arranged ‘warm way’, so all the frames had slid together when the hive fell and it’s possible the queen didn’t survive 7.

Spring honey, nucs and queens

The spring honey harvest went well. The OSR frames were mostly capped. Those that weren’t could still be extracted as the honey would not shake out of the frame.

A fat frame of spring honey

It was my best year for spring honey since returning to Scotland in 2015. With the exception of that one big storm the weather had been pretty good and the bees had had ample opportunity to be out foraging.

However, although a few of the colonies had newly mated and laying queens, the majority did not. In most of them I found evidence that there would be a laying queen sometime soon … I usually infer this from the presence of ‘polished’ cells in the centre of the one or two of the central frames in the hive. This gave me confidence that there was likely to be an unmated, or just mated, queen in the box. There’s nothing much to be gained from actually finding her, so I would have to be a bit more patient.

Just as these things cannot be rushed, an overcrowded nuc cannot be ignored.

Almost all the nucs were fast running out of space. I therefore removed 2-3 frames of brood from each and replaced them with fresh frames. I used the frames of brood to boost the honey production colonies that were ‘busy’ requeening.

Mid-June and the foxgloves are in flower

By the 14th of June I was back on the west coast.

Late June rearrangements

I returned a fortnight later for a very busy couple of days of beekeeping.

By this time the summer nectar flow was starting. The nucs, even those ‘weakened’ by removing brood, were busy filling spaces with brace comb.

Comb in feeder

All of the requeening colonies were checked for a laying queen. A handful had failed, disappeared or whatever and now looked queenless. These were requeened by uniting them with a nuc containing the ‘saved’ queen from earlier in the season.

What could be simpler? That’s one of the main attractions of this method of swarm control.

The colonies with the first of the new laying queens were doing really well, with lovely fresh frames of wall-to-wall brood. It’s only after a queen has laid up a full frame or two that you get a proper impression of her quality. I can never properly judge this in the tiny little frames of a mini-mating nuc, so – despite the extra resources (bees, frames, boxes) needed – prefer to get queens mated and laying in hives with full-sized frames.

Good laying pattern

The remaining ‘unused’ nucs were all expanded up to full hives and given a super. All the strong colonies in the apiaries were again given three supers and left to get on with things.

Expanded nucs on the left, production hives on the right

It was a backbreaking few days, particularly because I spent the evenings jarring honey 8, but it left the apiaries in a good state for the summer nectar flow.

Summer honey

The only beekeeping I did in July was on the west coast of Scotland. I moved a couple of nucs up to full hives and, since the heather wasn’t yet in full flower, I gave them each a gallon or so of thin syrup to encourage the bees to draw comb to give the queen space to lay.

Welcome to your new home … nuc ‘promoted’ to hive with contact feeder in place

I finally returned to Fife to take the summer honey off in late August. I’ve recently posted a brief description of clearing supers during Storm Francis so won’t repeat it here.

In four days I removed all the supers and extracted the honey, fed and treated the bees for the winter, and left the colonies strapped up securely for … goodness knows when.

The summer honey harvest was unusual. One of my apiaries did fantastically well, more than the last two seasons combined, and by far my best year since 2015.

The other apiary was just slightly worse than … utterly pathetic.

This second apiary is usually very reliable. The forage in the area has been dependable and, in some years, the lime has yielded very well. However, not this year and, since I wasn’t about, I don’t know why.

I did it my way … but it wasn’t very satisfying

That last paragraph rather neatly sums up the 2020 beekeeping season.

Overall the season must be considered a success; I didn’t lose any swarms, the majority of colonies were requeened successfully, all of the colonies are going into the winter strong, fed and treated, and the overall honey crop was very good.

However, it’s all been done ‘remotely’, both literally and figuratively. I’ve not felt as though I’ve been able to watch the season and the colonies develop together. I don’t feel as though I was ‘in tune’ with what was happening in the hives. I can’t explain why some things worked well and other things – like the apiary with no honey 🙁 – failed miserably.

My notes are perfunctory at best, “+3 supers, Q laying well”, and contain none of the usual asides about what’s happening in the environment. There’s no indication of what was flowering when, whether the year was ‘early’, ‘late’, or ‘about normal’, when the migrant birds arrived or left.

I’ve done less beekeeping this year than in any year in at least a decade. Since I rather like beekeeping, this means it has been a bit of a disappointment. Since I’ve spent less time with the bees, and I’ve been so rushed when I have been working with them, I feel as though I’ve learnt less this year than normal.

What didn’t get done?

With irregular and infrequent visits some things were simply ignored this season.

I did very little Varroa monitoring. With the Apivar strips now in it’s clear that some hives have higher Varroa counts than I’ve seen in the last few years 9. However, not all of them. Some colonies appear to have extremely low mite loads.

We finally managed to check the levels of deformed wing virus in our research colonies quite late in the season once the labs partially reopened. The levels were reassuringly low. This strongly suggests that the mite levels are not yet at a point threatening the health of the colonies.

I’ve singularly failed to do much in the way of brood comb exchange this season. This means I’m going to have to take a bit more care next year to cycle out the old, dark frames and replace them with brand new ones.

Here’s one I did manage to replace

Again, not the end of the world, but ‘bad beekeeping’ all the same.

As I’m putting the finishing words together for this post the government is re-introducing further curfews and restrictions … maybe next year will be more of the same?


 

The gentle art of beekeeping

High summer.

The swarm season had been and gone. The June gap was over. Grafts made at the peak of the swarm season had developed into lovely big fat queen cells and been distributed around nucleus colonies for mating.

That was almost six weeks ago.

From eclosion to laying takes a minimum of about 8 days. The weather had been almost perfect for queen mating, so I was hopeful they’d got out promptly, done ‘the business’, and returned to start laying.

That would have been about a month ago.

Good queens

I’d spent a long morning in the apiary checking the nucs and the colonies they were destined for. In the former I was looking for evidence that the queen was mated and laying well. That meant looking for nice even frames of sealed worker brood, with some – the first day or two of often patchy egg laying – now emerging.

Brood frame with a good laying pattern

It was warming up. More significantly, it was getting distinctly close and muggy. I knew that thunderstorms were predicted late in the afternoon, but by late morning it already had that oppressive ‘heavy’ feel to the air. Almost as though there wasn’t quite enough oxygen in it.

Never mind the weather, the queens were looking good. 90% of them were mated and laying well.

Just one no-show. She’d emerged from the cell, but there was no sign of her in the nuc, and precious few bees left either.

Queenless nucs often haemorrhage workers to nearby queenright colonies (or nucs), leaving a pathetic remainder that may develop laying workers. There’s no point in trying to save a colony like that.

Actually, it’s not even a colony … it’s a box with a few hundred abandoned and rapidly ageing workers. Adding resources to it – a new queen or a frame of eggs and young larvae – is almost certainly a waste of resources. They’d better serve the colonies they were already in. The remaining workers were probably over a month old and only had another week or two before they would be lost, ‘missing in action’, and fail to return from a foraging flight.

If you keep livestock, you’ll have dead stock.

These weren’t dead stock, but they were on their last legs, er, wings. I shook the workers out in front of a row of strong colonies and removed the nuc box so there was nowhere for them to return. The workers wouldn’t help the other colonies much, but it was a better fate than simply allowing them to dwindle.

Spare queens

Most of the nucs were going to be used to requeen production colonies. A couple had been promised to beginners and would be ready in another week or so.

Midseason is a good time to get a nuc to start beekeeping. The weather – the predicted (and seemingly increasingly imminent) afternoon thunder notwithstanding – is more dependable, and much warmer. The inevitably protracted inspections by a tyro won’t chill the brood and nucs are almost always better tempered than full colonies. In addition, the new beekeeper has the pleasure of watching the nuc build up to a full colony and preparing it for winter. This is a valuable learning experience.

Late season bramble

Late season bramble

It’s too late to get a honey crop from these midseason nucs (usually, there may be exceptional years) but that’s probably also good training for the new beekeeper. An understanding that beekeeping requires a degree of patience may be a tough lesson to learn but it’s an easier one than discovering that an overcrowded nuc purchased in April, swarms in May, gets really ratty in June and needs a new queen at the beginning of July.

But, after uniting the nucs to requeen the production hives it turned out that I had one queen spare.

Which was fortunate as I’d been asked by a friend for an old leftover queen to help them improve the behaviour of their only colony. Rather than give them one of the ageing queens she could have the spare one from this year.

A queen has a remarkable influence over the behaviour and performance of the colony. Good quality queens head calm, strong colonies that are a pleasure to work with. But it’s not all good genes. You can sometimes detect the influence of a good new queen in a poor colony well before any of the brood she has laid emerges. I assume this is due to pheromones (and with bees, if it’s not genetics or pheromones I’m not sure what else could explain it – ley lines, phase of the moon, 5G masts nearby?).

Go west, young(er) man

My friend lived about 45 minutes away. I found the queen in the nuc, popped her into a marking cage and placed her safely in light shade at the back of the apiary while I rearranged the nuc for uniting over a strong queenright colony.

A few minutes later I’d recovered the queen, clipped her and marked her with a white Posca pen. I alternate blue and white (and sometimes yellow if neither of those work or can be found) and rely on my notes to remind me of her age should I need to know it. I’m colourblind and cannot see – or at least distinguish – red and green, either from each other or from lots of other colours in the hive.

I transferred the marked queen into a JzBz queen cage and capped the exit tube. Of all the huge variety of queen introduction cages that are available these are my favourite. They’re also the only ones I was given a bucket of … something that had a big part to play in influencing my choice 🙂

JzBz queen cages

I put the caged queen in the breast pocket of my beesuit, extinguished the smoker and tidied up the apiary. It was warm, dark and humid in the pocket – for an hour or so she would be fine.

Actually, it was getting increasingly humid and the heaviness in the air was, if anything, getting more oppressive.

What I’d really like now would be a couple of large mugs of tea … I’d inspected a dozen large colonies and nearly the same number of nucs. The colonies that needed requeening had been united with the nucs (having found and removed the ageing queens) and I’d neatly stacked up all the empty nuc boxes in the shed. Finally, I’d retuned all the supers, some reassuringly heavy, and left everything ready for the next inspection in a fortnight or so 1.

That’s a lot of lifting, carrying, bending, squinting, prising, turning, rearranging and then gently replacing the crownboard and the roof.

Not really hard work, but enough.

Actually, quite enough … I’d really like that cuppa.

Was that thunder? Way off to the west … a sound so faint I might have imagined it. There were towering cumulus clouds building along the horizon.

Cloud

Threatening

Time to get a move on.

With the car packed I lock the apiary gate and set off.

West.

Leaving the flat agricultural land I climbed gently into low rolling hills. The land became more wooded, restricting my view of the thunderheads building, now strongly, in the direction I was heading. The sun was now intermittently hidden between the wispy clouds ahead of the storm front.

Could you do me a favour?

The bad weather was still a long way off. I’d have ample time to drop the queen off, slurp down a cuppa and be back home before any rain arrived. If my friend was sensible she’d just leave the new queen hanging in her cage in a super. The workers would feed her until the weather was a little more conducive to opening the hive and finding the old queen.

I pull into the driveway and my friend comes out to meet me. We share beekeeping chat about the weather, forage, the now-passed swarm season, the possibility of getting a nuc for next season 2.

“Could you perhaps requeen the colony? I’m really bad at finding the queen and they’ve been a bit bolshy 3 recently. I’ll put the kettle on while you’re doing it.”

I did a quick mental calculation … weighing up the positives (kettle on) and the negatives (bolshy, the distant – but approaching – thunder) and was surprised to find that my yearning for a cuppa tipped the balance enough for me to agree to do it.

I returned to the car for my smoker and some queen candy which I used to plug the neck of the JzBz cage. At the same time I also found a small piece of wire to hang the cage between the frames from.

“They’re in the back garden on the bench by the gate to the orchard.”

I look through the kitchen window across the unkempt lawn (was the mower broken?). Sure enough, there was a double brooded National hive topped with two supers on a garden bench about 30 metres away.

“I’ll stay here if you don’t mind … they gave me a bit of a fright when I last checked them.”

Sure. No problem. I’ve done this a hundred times. White, no sugar and, yes, I’d love a cookie as well.

Be properly prepared

I stepped into the back garden and fired up the smoker. It was still warm from being used for my own bees and the mix of cardboard, woodshavings and dried grass quickly started smouldering nicely. A couple of bees had come to investigate but had just done a few laps of my head and disappeared.

But they returned as I walked across the lawn.

And they brought reinforcements.

By the time I was half way across the lawn I’d been pinged a couple of times. Not stung, but the sort of glancing blow that shows intent.

A shot across the bows, if you like.

I didn’t like.

I pulled the veil over my head and zipped it up quickly, before rummaging through my pockets to find a pair of gloves. Mismatched gloved. A yellow Marigold for my left hand and a thin long-cuff blue nitrile for my right. It’s an odd look 4 but an effective combination. The Marigold is easy to get on and off, and provides ample protection.

Nitriles ...

Nitriles …

The nitrile is a bit of a nightmare to get on when it’s still damp inside. Another couple of bees dive bomb my veil, one clinging on and making that higher pitched whining sound they make when they’re trying to get through. I brushed her off with the Marigold, turned the nitrile inside out, blew into it to inflate the fingers, and finally got it on.

Why two different gloves? Two reasons. I’d lost the other Marigold and because nitriles are thin enough to easily pick a queen up with, and that’s what I’d been doing most of the morning.

And hoped to do again shortly when I found the old queen in the agitated colony.

Opening hostilities

I approached the hive. It was a strong colony. Very strong. It was tipped back slightly on the bench and didn’t look all that stable 5. I gave them a couple of puffs of smoke at the entrance and prised the supers up and off, placing them propped against the leg of the bench.

I was faintly aware of the smell of bananas and the, still distant, sound of thunder. It probably wasn’t getting any closer, but it certainly wasn’t disappearing either.

The thunder that is.

The smell of bananas was new … it’s the alarm pheromone.

Actually, it’s one of the alarm pheromones. Importantly, it’s the one released from the Koschevnikov gland at the base of the sting. This meant that one or two bees had already pressed home a full attack and stung me. Felt nowt. Presumably they’d hit a fold in the beesuit or the cuff of the Marigold.

Or my adrenaline levels were sufficiently elevated to suppress my pain response.

I was increasingly aware of the number of really unpleasant bees that were in the hive.

And, more to the point, coming out of the hive.

But I was most aware that I was only wearing a single thickness beesuit in the presence of 50,000 sociopaths with a thunderstorm approaching. Under the suit I had a thin short sleeved shirt and a pair of shorts.

It might be raining in half an hour … this could get ugly.

It was late July, it was a hot day, my bees are calm. I wasn’t dressed appropriately for these psychos.

I felt I needed chain mail … and an umbrella.

Time for a rethink

I gave the hive a couple of larger puffs from the smoker and retreated back to the car, ducking under and through – twice – some dense overhanging shrubs to deter and deflect the bees attempting to hasten my retreat.

Ideally I’d have put a fleece on under the beesuit. That makes you more or less impervious to stings.

Did I mention it was a warm day in July? No fleece 🙁

However, I did have a beekeeping jacket in the car. This is what I wear for most of my beekeeping (unless I’m wearing shorts). I removed the jacket hood and put it on over the beesuit, remembering to transfer the queen to the outer jacket pocket. I also found another nitrile glove and put it on to be double gloved.

“The queen’s not marked”, my friend shouted to me as I walked back across the garden, “Sorry!”

Now you tell me …

I See You Baby

I See You Baby

I returned to the hive. To reduce the immediate concentration of bees, I split the two brood boxes off the floor, placing each several metres away on separate garden chairs. I balanced the supers on the original floor to allow returning foragers and the increasing maelstrom of flying bees to have somewhere to return if needed.

And then I found the unmarked queen.

As simple as that.

Amazingly, it was on the first pass through the second brood box.

Each box was dealt with in the same way. I gently split the propolis sealing the frames together – first down one side of the box, then the other. I removed the outer frame, inspected it carefully and placed it on the ground leaning against the chair leg. With space to work I then methodically went through every frame, calmly but quickly.

I didn’t expect to find her so easily. I wasn’t sure I’d be able to find her at all.

It helped that she was huge and pale. It helped that she was calmly ambling around on the frame, clearly confident in the knowledge that there were 50,000 acolytes willing to lay down their lives to protect her.

Her confidence was misplaced 🙁

Veiled threat

And then a bee got inside the veil.

This happens now and then. I suspect they sneak through the gap where the zips meet at the front or the back. There are little Velcro patches to hold everything together, but it was an old suit 6 and the Velcro was a bit worn.

There are few things more disconcerting that 50,000 psychos encouraging a Ninja worker that’s managed to break through your defences and is just in your peripheral vision. Or worse, in your hair. With a calm colony you can retreat and deal with the interloper. You have to take the veil off. Sometimes you have to take the suit off.

Removing the veil would have been unwise. Perhaps suicidal. I retreated a few yards and dealt with the bee. It was never going to end well for one of us 🙁

Reassemble in the reverse order

Returning to the original bench, I removed the supers that were now festooned with thousands of bees, balancing them against the leg again. I found a pencil-thick twig and used it under one corner of the floor to stop everything wobbling. Both brood boxes were returned, trying to avoid crushing too many bees at the interface. A combination of a well aimed puff or two of smoke, brushing the bees away with the back of my hand and placing the box down at an angle and then rotating it into position reduced what can otherwise cause carnage.

I hung the new queen in her cage between the top bars of the central frames in the upper box, returned the queen excluder and the supers and closed the hive up.

It took 15 minutes to avoid and evade the followers before I could remove the beesuit safely. I’d been stung several times but none had penetrated more than the suit.

I finally got my cup of tea.

Confidence

This was several years ago. I took a few risks towards the end with the queen introduction but got away with it. The colony released the queen, accepted her and a month or so later were calm and well behaved.

I was lucky to find the queen so quickly in such a strong colony. I didn’t have to resort to some of the tricks sometimes needed to find elusive queens.

Ideally I’d have left the queen cage sealed to see if they were aggressive to her, only removing the cap once I was sure they’d accept her. This can take a day or two, but you need to check them.

There was no way I was going back into the hive and my friend definitely wasn’t.

The rain and thunder never arrived … like many summer storms it was all bluster but eventually dissipated as the day cooled.

This was the worst colony I’ve ever handled as a beekeeper. At least for out and out, close quarter, bare knuckle aggression. By any measure I’d have said they were unusable for beekeeping. I’ve had colonies with followers chase me 300 metres up the meadow, though the hive itself wasn’t too hot 7. This colony was an order of magnitude worse, though the followers were less persistent.

I suspect that aggression (or, more correctly, defensiveness) and following have different genetic determinants in honey bees.

Lessons

  • Knowing when to retreat is important. Smoking them gently before I returned to the car for a jacket helped mask the alarm pheromone in the hive and gave me both time to think and renewed confidence that I was now better protected.
  • Confidence is very important when dealing with an unpleasant hive. It allows you to be unhurried and gentle, when your instincts are screaming ‘get a move on, they’re going postal’.
  • Confidence comes with experience and with belief in the protective clothing you use. It doesn’t need to be stingproof, but it does need to protect the soft bits (my forearms, ankles and face react very badly when stung).
  • Indeed, it might be better if it’s not completely stingproof. It’s important to be aware of the reactions of the colony, which is why I prefer nitrile gloves to Marigolds, and why I never use gauntlets.
  • Many colonies are defensive in poor weather or with approaching thunderstorms. If I’d known just how defensive this colony were I’d have planned the day differently.
  • The unstable ‘hive stand’ would have agitated the bees in windy weather or during inspections.

Bad bees

It turned out the colony had been purchased, sight unseen, as a nuc the year before. By the end of the season it had become unmanageable. The supers had been on since the previous summer and the colony hadn’t been treated for mites.

They appeared healthy, but their behaviour was negatively influencing their management (and the upkeep of the garden). Beekeeping isn’t fun if you’re frightened of the bees. You find excuses to not open the hive, or not mow the lawn.

The story ended well. The new queen settled well and the bees became a pleasure to work with. My friend regained her confidence and is happy to requeen her own colonies now.

She has even started using proper hive stands rather than the garden bench … which you can now use for relaxing on with a mug of tea and a cookie.

While watching the bees 🙂


 

Bigging up nucs

The phrase bigging up [somebody or something] means saying they are very good, usually in public 1. It is slang and used informally and usage has increased significantly in the last couple of decades.

The term bigging in bigging up meaning promotion, is relatively new. However, the same word can be traced back to Middle English and (a bit more more recently) obsolete Scottish, when it meant build.

Two days work bigging a brick wall in the Braidfoots house 2.

Anyone who has used nucs, for queen mating or swarm control for example, is likely to big them up … as in sing their praises. Small enough to need only limited resources to start them, large enough to function as a self-contained and resilient colony etc.

However, in this post I’m going to discuss bigging up nucs in the older meaning of the phrase … building them up from a nuc to a full colony.

Which could also, of course, be considered as promoting them 😉

Problems with history and latitude

One of the perils of writing about beekeeping in the UK is the variation in the season between the south and the north of the country.

Just as you can’t be prescriptive in any one location about when certain events in a particular beekeeping year occur – e.g. swarming, winter bee production, broodlessness – it’s also pretty obvious that the season is longer 3 at lower latitudes.

It’s therefore not possible to say ‘in late May’ or ‘by mid-June’ nucs will start to be overcrowded 4. Not only does this depend upon the local climate, but it is also significantly influenced by how the nucs were prepared.

If the nuc was established for swarm control, started with the old queen and 1-2 frames of brood, it is likely to have built up rapidly and will quickly overrun the box if not dealt with promptly.

Alternatively, if the nuc was used for queen mating, started with a sealed cell (or virgin queen) and a frame of emerging brood, it will build up less fast as the queen has to get out and mate and then start laying.

Overcrowding

Whatever the history (or the latitude), at some point the colony will grow to be too large for the box. Then, but ideally earlier (so you are prepared), you need to decide what you are going to do with them.

With experience you can judge overcrowding by gently popping the lid up and peering through the thin plastic or polycarbonate crownboard. 

I use Thorne’s Everynucs which have an integral feeder at one end of the box. When they start building brace comb in the feeder they need to be given more space.

Here's one I prepared earlier

Here’s one I prepared earlier

The colony above is overwintered and very clearly overcrowded. The photo was taken in the third week of April (in Scotland). By mid-season, a colony that crowded would have probably swarmed.

Comb in feeder

The photo immediately above was taken in late June this year. The nuc was set up in mid-May for swarm control with the queen and just one frame of emerging brood.

However, in the intervening six weeks I had already removed two or three frames of sealed brood (but not adhering bees) to boost other colonies, replacing the frames with a mix of drawn comb and foundation, all of which had been drawn and filled again.

Nucs can build up very fast … be warned.

Decision time

Nucs are really versatile. Your choice includes (but isn’t restricted to):

  1. Overwintering the nuc
  2. Expanding the nuc into a full hive
  3. Uniting the nuc with a queenless colony
  4. Removing the queen and uniting the nuc with a queenright colony
  5. Leaving it too late and letting them swarm 🙁

I’m not going to discuss the last option, but it is an inevitability if the colony is healthy and there’s a reasonable amount of forage in the area. 

One more week’ for a nuc is usually not worth risking.

Overwintering nucs deserves a post of its own (and has been covered some time ago 5). It’s worth noting that nucs started in May for swarm control or for queen mating require a lot of maintenance if they are not to outgrow their accommodation by the end of the season. You need to regularly remove bees and brood or the colony will swarm.

It is much better to start nucs later in the season for overwintering.

Before doing anything with the nuc it is worth confirming that the queen appears well mated and is laying well 6. She should be producing frame after frame packed with brood. In new(ish) comb you can easily tell her quality based upon the presence of even sheets of brood, with relatively few missed cells.

Good laying pattern from queen in 5 frame nucleus

The frame above is from a nuc this spring. The majority of the missed cells, at least at the top of the frame, are due to the wires in the foundation.

Returning a marked and clipped queen to a nuc

And, while you’re at it, use this opportunity of the last inspection of the nuc to mark and clip the queen (if she isn’t already). It’s always easier to find a queen in a nuc – fewer bees, less frames to hide on the other side of etc.

From nuc to a full brood box

This is about as easy as it gets and should take no more than 5 minutes if you have everything to hand.

  1. Move the nuc a metre or so away from its original location.
  2. Place a new floor and a brood box on the original site.
  3. The brood box should contain a couple of frames of drawn comb if you have them, or frames with fresh foundation. Place one next to each side wall (see note below for comment on warm and cold way).
  4. If the floor has open mesh I slide in the Varroa tray. I do not want the bees to be distracted by smells from other ‘potential’ routes into the hive.
  5. Open the nuc using a very small amount of smoke 7.
  6. Remove the dummy board from the nuc and gently separate the frames if they’re propolised together.
  7. Transfer each frame to the new brood box maintaining their position and orientation relative to the neighbouring frames. Arrange the frames from the nuc close to the new hive entrance (see below).
  8. Ideally , make sure the queen is seen … just to give you confidence 🙂
  9. Move the second new frame of drawn comb or foundation to ‘sandwich’ the frames from the nuc.
  10. Fill the rest of the box with frames containing drawn comb or new foundation.
  11. Replace the dummy board removed in #6 above.
  12. Add syrup if needed – see below.
  13. Replace the crownboard and roof.
  14. Reduce the entrance to help the colony defend their new, much larger, residence.

Feeding

If there is a good nectar flow you may not need to feed the colony. If you’ve used new foundation rather than drawn comb then they probably will need feeding. It’s important they draw new comb so the queen can continue laying uninterrupted. This ensures they build up rapidly.

Use thin syrup (1:1 by weight of sugar and water) in a contact feeder. 

I usually give nucs a gallon or so of syrup to help them draw comb. They use this surprisingly fast. Check them every 48 hours. 

Welcome to your new home … nuc ‘promoted’ to hive with contact feeder in place

My crownboards lack holes, so I place the contact feeder directly above the top bars, separated by a couple of spare frame bottom bars. I add a super to ‘house’ the contact feed and then close the hive up.

Defending the hive

All of my full-sized hives are arranged warm way. This means the frames are parallel with the entrance of the hive. The alternative, cold way, has the frames perpendicular to the entrance.

To help the small colony defend the new large box they are in, the nucleus frames should be located close to the hive entrance.

The hive entrance is on the left with the frames arranged ‘warm way’.

Initially, these are the frames that are covered in bees, so providing a deterrent to any potential robbers.

It may also help to reduce the size of the hive entrance so the bees only need to defend an inch wide hole, rather than the full width of the box.

If your hives are organised cold way’ the same requirements apply – arrange the bees near to the entrance and reduce the entrance width. For example, place the frames in the centre of the hive, flanked on each side by three new frames, and leave a narrow central entrance open.

Finally, do not slop syrup around all over the place when feeding them. It’s a near-certain way to encourage robbing (particularly if there’s a shortage of nectar).

Uniting the nuc with a queenright or queenless colony

I can deal these two together because the only difference is where the queen is in the stacked boxes at the end of the procedure.

Collect together the things you will need:

  • A new brood box
  • Two sheets of newspaper
  • Six frames of drawn comb or foundation

Queens

If the hive and the nuc are both queenright you must remove the unwanted queen 8.

Typically this is when you have used the nucleus method of swarm control. The colony has reared a good new queen and the old queen in the nuc is now surplus to requirements.

Alternatively, the colony might have generated a sub-standard or poorly mated queen and you want a single united colony headed again by the original queen.

If the old(er), unwanted queen is still laying OK consider offering her to someone else in your association. Remove the queen, does not necessarily mean sacrifice her. 

Caged queen with attendants

Place the queen in a introduction cage with some attendant workers and some candy. Put her somewhere safe (the breast pocket works for me) and give her to someone who needs her more than you do … perhaps in exchange for a nice bottle of merlot 9 😉

Don’t risk leaving two queens in the same box and hoping the ‘better’ one (i.e. the one you want) will survive the ruckus that will happen. 

Sod’s Law dictates that the queen you want will not make it … particularly if it’s late in the season, she’s particularly good or she’s otherwise precious.

Uniting

I generally move the nuc to the hive it is being united with. Waft some smoke at the hive entrance, remove the roof and gently lift the corner of the crownboard. Add a second gentle puff of smoke into the gap and let the bees move down.

Remove the crownboard and gently lay two intact sheets of newspaper flat over the tops of the frames. It helps to remove brace comb from the top bars as it can puncture the newspaper and lead to premature mixing and a bit of a melee.

In the good old days a single page from a broadsheet 10 newspaper was sufficient. These days I think you have to read the Financial Times to achieve this

Assuming you’re not Gordon Gekko, a hedge fund manager or derivatives trader you will probably need two slightly overlapping sheets. Don’t bother about moving all the bees off the top bars – they’ll move down soon enough once you put the newspaper on.

If it’s windy use your initiative, recruit a helper or evolve at least one additional limb to hold the newspaper in place.

Add a second empty brood box on top.

Make a small hole (about the size of the o in hole) in the sheet using your hive tool, somewhere near the middle, above a gap between two frames. You can just see the hole above the curve of the hive tool here …

Newspaper, second brood box and a very small hole

Add two or three frames of drawn comb or foundation. Transfer all the frames from the nuc to the new brood box, as before, maintaining their order and orientation. Fill the rest of the box with frames, shake in the last bees from the nuc box and close the hive up.

Just checking!

As before, if you are uniting a queenright nuc with a queenless hive, it’s always good to be certain the queen was on one of the frames transferred to the new box.

Have patience

Hives usually have sufficient stores at this time of the season. If both boxes are light you might have to feed them syrup (to help them draw comb) or fondant (just to tide them over until the nectar flow starts).

Leave them to it. There’s nothing to be gained by ‘having a peek’. The bees will chew their way through the newspaper in 24-48 hours.

Successful uniting ...

Successful uniting …

Look out for a pile of shredded newspaper falling through the open mesh floor and, after a week, continue inspections as normal.

Miscellaneous final thoughts

If the recipient hive is broodless it will end up with lots of space and empty frames. Under those circumstances I usually unite them down to a single box. Rather than adding additional frames to the top box I use a fat dummy to fill the space.

Uniting a nuc with a full colony

Uniting a nuc with a full colony …

A block of polystyrene tightly wrapped in a bin bag works just as well 11.

A week after uniting them rearrange the brood-containing frames with pollen and stores into a single box and remove the empty frames and unwanted second brood box.

Lost bees

How will the bees reorientate to the new location?

Don’t worry. The bees from the nuc will discover that everything is changed when they have to muscle their way through the lower brood box to reach the hive entrance. They will quickly reorientate to the new hive.

Some of the workers from the nuc will have been out foraging when you rudely removed their home. They will, in time, move to a nearby hive and blag their way in 12

Where has the house gone?

You can speed this process up by removing the hive stand the nuc was on. With nowhere to land they quickly find an adjacent hive. If I unite colonies in poor weather (or just before rain starts 13) I’ll try and minimise the number of stranded bees by doing this.

For the same reason I prefer not to unite late in the afternoon to give the bees time to relocate. 

Supers

When I was younger and much better organised I’d clear the supers in advance on the recipient hive. I’d visit the apiary 24 hours before I intended to unite them and add a clearer board. When preparing the recipient colony I’d put the (now emptied) supers aside, unite the colonies and then add the supers back on top (all on the same visit). 

These days I’m definitely older and usually less well organised 🙁

Newspaper and queen excluder

If I’ve forgotten to clear the supers I’ll also unite the bees in the supers over the nuc. I separate them with newspaper as before and add a queen excluder to stop the queen moving up into the supers.

All that then remains to do is tidy up the apiary and go home for a cup of tea.

Time to tidy up and go home


 

A June Gap

As far as the beekeeping season is concerned, we’ve had the starter and we’re now waiting for the main course. 

Like restaurants, the size of the ‘starter’ depends upon your location. If you live in an area with lots of oil seed rape (OSR) and other early nectar, the spring honey crop might account for the majority of your annual honey.

If you are in the west, or take your hives to the hills, you might have skipped the starter altogether hoping the heather is the all-you-can-eat buffet of the season.

Lockdown honey

In Fife they appear to be growing less OSR as the farmers have had problems with flea beetle since the neonicotinoid ban was introduced.

Nevertheless, my bees are in range of a couple of fields and – if the weather behaves – usually get a reasonable crop from it. My earlier plans to move hives directly onto the fields, saving the bees a few hundred yards of flying to and fro, was thwarted (like so much else this year) by the pandemic.

The timing of the spring honey harvest is variable, and quite important. You want it to be late enough that the bees have collected what they can and had a chance to ripen it properly so that the water content is below 20% 1.

However, you can’t leave it too late. Fast-granulating OSR honey sets hard in the frames and then cannot be extracted without melting. In addition, there’s often a dearth of nectar in the weeks after the OSR finishes and the bees can end up eating their stores, leaving the beekeeper with nothing 🙁

Judging all that from 150 miles away on the west coast where I’m currently based was a bit tricky. I had to timetable a return visit to also check on queen mating and the build up of all the colonies I’d used the nucleus method of swarm control on.

Ideally all in the same visit.

Blowin’ in the wind

I’d made up the nucs, added supers and last checked my colonies around the 17-19th of May. I finally returned on the 10th of June.

In the intervening period I’d been worried about one of my more exposed apiaries. I’d run out of ratchet straps to hold the hives together and was aware there had been some gales in late May.

Sure enough, when I got to the apiary, there was ample evidence of the gales …

How the mighty fall

The only unsecured hive was completely untouched and the bees were happily working away. However, one of the strapped hives had been toppled and was laying face (i.e. entrance) down. You can see the dent in the fence where it collided on its descent.

If she hadn’t already (and I expect she hadn’t based upon the date of the gales) I suspect the queen struggled to get out and mate from this hive 🙁

Nuked nucs

Two adjacent 8-frame nucs were also sitting lidless in the gentle rain. The lids and the large piece of timber they’d been held down with were on the ground. The perspex crownboards were shattered into dozens of pieces.

These bees were fine.

Both queens were laying and the bees were using the new top entrance (!) for entering and leaving the hive. They were a little subdued and the colonies were less well developed than the other nucs (see below). However, their survival for the best part of three weeks uncovered is a tribute to their resilience.

They were thoroughly confused how to get back into the hive after I replaced the lids 🙂

Slow queen mating

Other than extracting, the primary purpose of this visit was to check the queenright nucs from my swarm control weren’t running out of space, and to check on the progress of queen mating in the original colonies.

Queen mating always takes longer than you expect.

Or than I expect at least.

Poor weather hampered my inspection of all re-queening colonies but, of those I looked at, 50% had new laying queens and the others looked as though they would very soon.

By which I mean the colonies were calm and ‘behaved’ queenright, they were foraging well and the centre of the ‘broodnest’ (or what would be the centre if there was any brood) was being kept clear of nectar and had large patches of polished cells.

Overall it was a bit too soon to be sure everything was OK, but I expect it is.

However, it wasn’t too soon to check the nucs.

Overflowing nucs

In fact, it was almost too late …

With one exception the nucs were near to overflowing with bees and brood.

I favour the Thorne’s Everynuc which has an integral feeder at one end of the box. Once the bees start drawing comb in the feeder they’re running desperately short of space.

Most had started …

Here's one I prepared earlier

Here’s one I prepared earlier

I didn’t photograph any of the nucs, but the photo above (of an overly-full overwintered nuc) shows what I mean; the feeder is on the right.

The nucs had been made up with one frame of predominantly emerging brood, a few more nurse bees, two foundationless frames, a frame of drawn comb and a frame of stores.

They were now all packed with 5 frames of brood and would have started making swarm preparations within a few days if I hadn’t dealt with them.

Good laying pattern from queen in 5 frame nucleus

And the queens had laid beautiful solid sheets of brood (always reasonably easy if the comb is brand new).

Housekeeping and more swarm prevention

The beauty of the nucleus method of swarm control is that you have the older queen ‘in reserve’ should the new queen not get mated, or be of poor quality.

The problem I was faced with was that the new queens weren’t all yet laying (and for those that were it was too soon to determine their quality), but the older queen was in a box they were rapidly outgrowing.

I therefore removed at least three frames of brood 2 from each nuc and used it to boost the re-queening colonies, replacing the brood-filled frames with fresh foundation 3.

The nucs will build up again strongly and the full colonies will benefit from a brood boost to make up for some of the bees lost during requeening. Some of the transferred frames had open brood. These produce pheromones that should hold back the development of laying workers.

Finally, if the requeening colonies actually lack a queen (the weather was poor and I didn’t search very hard in any of them) there should be a few larvae young enough on the transferred frames for them to draw a new queen cell if needed.

I marked the introduced frames so I can check them quickly on my next visit to the apiary.

This frame needs to be replaced … but could be used in a bait hive next year

The additional benefit of moving brood from the nucs to the full colonies is that it gave me an opportunity to remove some old, dark frames from the latter.

Shown above is one of the removed frames. As the colony is broodless 4 and there’s the usual reduction in available nectar in early/mid June, many of the frames in the brood box were largely empty and can easily be replaced with better quality comb.

Everyone’s a winner 😉

Drone laying queen

One of the nucs made in mid/late May had failed. The queen had developed into a drone layer.

Drone laying queen

The laying pattern was focused around the middle of frame indicating it had been laid by a queen. If it had been laying workers the drone brood would be scattered all over the frames.

There was no reasonable or efficient way to save this colony. The queen was removed and I then shook the bees out in front of a row of strong hives.

I was surprised I’d not seen problems with this queen when making up the nucs in May 5. I do know that all the colonies had worker brood because the nucs were all made containing one frame of emerging (worker) brood.

Perhaps the shock of being dumped into a new box stopped her laying fertilised eggs. Probably it was just a coincidence. We’ll ever know …

Extraction

And, in between righting toppled hives, checking for queens, stopping nucs from swarming, moving a dozen hives/nucs, boosting requeening hives and replacing comb … I extracted a very good crop of spring honey.

Luvverrrly

Although I had fewer ‘production’ hives this season than previous years (to reduce my workload during the lockdown) I still managed to get a more than respectable spring harvest. In fact, it was my best spring since moving back to Scotland in 2015.

The crop wasn’t as large as I’d managed previously in Warwickshire, but the season here starts almost a month later.

A fat frame of spring honey

I start my supers with 10 or 11 frames, but once they are drawn I reduce to 9 frames. With a good nectar flow the bees draw out the comb very nicely.

The bees use less wax (many of my frames are also drawn on drone foundation, so even less wax than worker comb 6), it’s easier to uncap and I have fewer frames to extract.

Again … everyone’s a winner 😉

Not the June gap

Quite a few frames contained fresh nectar, so there was clearly a flow of something (other than rain, which seemed to predominate during my visit) going on. These frames are easy to identify as they drip nectar over the floor as you lift them out to uncap 🙁

In some years you find frames with a big central capped region – enough to usefully extract – but containing lots of drippy fresh nectar in the uncapped cells at the edges and shoulders. I’ve heard that some beekeepers do a low speed spin in the extractor to remove the nectar, then uncap and extract the ripe honey.

I generally don’t bother and instead just stick these back in the hive.

If there’s one task more tiresome than extracting it’s cleaning the extractor afterwards. To have to also clean the extractor during extracting (to avoid the high water content nectar from spoiling the honey) is asking too much!

Colonies can starve during a prolonged nectar dearth in June. All of mine were left with some stores in the brood box and with the returned wet supers. That, plus the clear evidence for some nectar being collected, means they should be OK.

National Honey monitoring Scheme

I have apiaries in different parts of Fife. The bees therefore forage in distinct areas and have access to a variety of different nectar sources.

It’s sometimes relatively easy to determine what they’ve been collecting nectar from – if the back of the thorax has a white(ish) stripe on it and it’s late summer they’re hammering the balsam, if they’ve got bags of yellow pollen and the bees are yellow and the fields all around are yellow it’s probably rape.

Mid-April in the apiary ...

Mid-April in a Warwickshire apiary …

But it might not be.

To be certain you need to analyse the pollen.

The old skool way of doing this is by microscopy. Honey – at least the top quality honey produced by local amateur beekeepers 7 – contains lots of pollen. Broadly speaking, the relative proportions of the different pollens – which can usually be distinguished microscopically – tells you the plants the nectar was collected from.

The cutting edge way to achieve the same thing in a fraction of the time (albeit at great expense) is to use so-called next generation sequencing to catalogue all the pollen present in the sample.

Pollen contains nucleic acid and the sequence of the nucleotides in the nucleic acid are uniquely characteristics of particular plant species. You can easily get both qualitative and quantitative data.

And this is exactly what the National Honey Monitoring Scheme is doing.

They use the data to monitor long-term changes in the condition and health of the countryside” but they provide the beekeeper’s involved with the information of pollen types and proportions in their honey.

National Honey Monitoring Scheme samples

Samples must be taken directly from capped comb. It’s a messy business. Fortunately the labelling on the sample bottles is waterproof so everything can be thoroughly rinsed before popping them into the post for future analysis.

I have samples analysed already from last year and will have spring and summer samples from a different apiary this season. I’ll write in the future about what the results look like, together with a more in-depth explanation of the technology used.

When I last checked you could still register to take part and have your own honey analysed.


Notes

Under (re)construction

Lockdown means there have been more visitors than ever to this site, with numbers up at least 75% over this time last year.

This, coupled with the need to upgrade some of the underlying software that keeps this site together, means I’m in the middle of moving to a bigger, faster, better (more expensive 🙁 ) server. I’m beginning to regret the bloat of wordpress over the lean and mean Hugo or Jekyll-type templating systems (and if this means nothing to you then I’m in good company) and may yet switch.

In the meantime, bear with me … there may be some broken links littering a few pages. If it looks and works really badly, clear your browser cache, re-check things and please send me an email using the link at the bottom of the right hand column.

Thank you
