How To Populateoseko jobeencat

When I started keeping bees at the turn of the century, the choice of hive here in the UK was National or WBC or, if you had bigger ambitions, Commercial. The Langstroth was regarded as unnecessarily American and anything made from straw was merely quaint at best, and at worst, a disaster waiting to happen. Now, less than 20 years later, we also have the Warré, the horizontal top bar hive, the Lazutin, the ZEST and other deep boxes, and for straw lovers, some interesting variants on the skep. This has created two new problems for the beginner: which hive to start with and how to persuade bees into it.

In those days it was easy: the National was the go-to choice because of its ubiquity. Those who liked the look of the WBC and were not put off by the extra work could still use the same frames, albeit fewer of them. You paid around £25 for an overwintered nuc and about twice that for a hive and in a flash you were a new beekeeper.

Somehow, in the intervening couple of decades, prices of nucs doubled, and doubled again, and again, and prices of the woodenware also increased, such that there is now a significant cost to starting in beekeeping. If you go down the conventional route: you can expect to lay down around £500 for a hive with bees and basic kit.

If you take the road less travelled and build your own top bar hive – vertical or horizontal – you can certainly save money on hardware, but now you have another problem: how to get bees into your hive, given that a standard 5-frame nuc will not fit into your odd-shaped box, and suitable nucs are as rare as hen’s teeth.

When I began to teach beginners about top bar hives, we used a rather brutal technique that we called “crop and chop”, which involved performing drastic and irreversible surgery on the frames and combs of a standard nuc in order to force it to fit the trapezoidal form of a horizontal top bar hive. It worked reasonably well, but required a bee-proof covering over and around the de-framed bars and was significantly messy if there was a full frame of brood to deal with. A better method had to be found.

My standard advice was – and still is – if possible, start with a swarm. Ideally, start by baiting a swarm directly into your hive, as this provides strong evidence that by choosing to be there, they consider it high on their list of ideal homes and they are more likely to thrive than not. Swarms can be attracted to hives by baiting them with some empty comb from another (healthy) hive, rubbing wax and propolis around the woodwork, and by adding a few drops of my Magic Swarm Bait, which comprises one part geranium essential oil to two parts lemongrass oil.

The great thing about swarm baiting is that you can set up a number of boxes that are really just small hives – 10-12 bars is good for a TBH bait box – and place them in several different locations to multiply your chances of success. The not-so-great thing is that you are relying on bees finding your boxes, which is quite likely in an area containing a fair number of beekeepers, but progressively less likely the further you are away from civilization. If you are more than a couple of miles from other beehives or wild-living colonies, your chances diminish exponentially (I suspect that it follows the inverse square law: your chances are inversely proportional to the square of the distance from the nearest apiary).

You can become proactive and put yourself about as a swarm catcher, which may produce a better outcome, providing you don’t mind dealing with multiple enquiries about bumblebees under sheds, hoverflies masquerading as bees and actual honeybees that have taken up residence in chimneys, attics and walls. Not to mention wasps and hornets. With luck, at least once per season, you will be offered a football-sized, prime swarm, hanging from the horizontal branch of an apple tree, conveniently at shoulder height. This is the one to install in your horizontal top bar hive, by pouring it into the box as if it were liquid, or running it up a slope into your Warré. These bees are in perfect condition to get you off to a great start: full of honey and enthusiasm, they will get busy building combs and all you need to do is watch in awe.

But supposing the season is passing you by and no swarm has appeared. You desperately want to get started, and you are looking at ads for nucs, which you suspect are headed by an imported queen. Or perhaps a friend has bees in their National, which are looking like they may have swarmy ambitions. How can you get bees from frames to top bars without hacking through wood and brood? Is it even possible?

Luckiy, it is not only possible, but quite easy to perform.

For a ‘standard’ top bar hive (using 17″ bars) you need temporary access to – or ownership of – a National hive brood box containing 5-8 good frames of bees and brood, with or without a honey super. This can be a nuc that you have bought and placed into a full-size brood box, or it could be a friend’s hive that they don’t mind you playing with. (I should say that this operation can also be performed as described using Langstroth or any other type of frame hive, provided the bars in your TBH are the same length as those in the frame hive.)

The method is as follows:

Place the occupied hive (the one containing your nucleus plus extra frames) in the exact location where your top bar hive will later stand, with its entrance facing in the direction chosen to be least likely to cause annoyance to you or your neighbours.
Separate frames containing brood into pairs and place a top bar between each pair, restoring spacing to normal. (This is why you start with less than a full complement of frames.)
Leave for 7-10 days, then carefully check the bars for combs. The bees will have drawn straight comb on each bar, into which the queen will have laid eggs, some of which may have grown to the pupal stage already. You may well find the queen on one of the new combs.
On a sunny afternoon, move the occupied hive several paces in any convenient direction, and place the TBH in its former position. You will notice returning foragers arriving home, looking puzzled that their home has changed shape, but quickly finding the new entrance.
Carefully transfer the newly-drawn top bar combs, with adhering bees, and place them side by side in the TBH, checking to see if the queen is on one of them. If she is, well and good. If not, then you need to find her and move her into the new hive, taking care that she doesn’t take flight.
Now you need to shake about half the bees from the frame hive into the TBH, adding several bars either side of those already there. Place follower boards and close up.
Close the frame hive, after adding new frames to fill the gaps created by removing the top bars.
Now you have a queen-right colony in your top bar hive, with foragers bringing in food as if nothing has happened, and a queenless colony in the National, with the resources to make themselves a new queen (check they have eggs and newly-emerged larvae). Unless there is a flow on, I suggest you feed both colonies at this point: one needs to build comb, while the other needs to draw make a queen.
The principle we are exploiting here is the ability of bees to return to the exact point in space where they know their home to be – or to have been when they left to look for food. This can be used tomove bees from literally any hive to any other, provided the new box can be substituted for the old. The additional step of persuading them to build suitably movable combs in advance of the transfer makes the process easier, but is not essential. You may need to balance the populations in old and new colonies, which is where your judgement as a beekeeper comes into play.

Transferring a colony from frames to a Warré could be done by similar means, but you would have to make some special frames and blank off the areas either side, to prevent comb being built where it will not fit. An easier method – especially during the build-up period – is to place the National brood box on top of a Warré box, with a plywood ‘mask’ in between to reduce the aperture to 250mm and division boards in the National to prevent sideways expansion. The entrance should be below the lower box. Comb-builders will get busy to enable downward expansion, and if you place two or more boxes under the first, you can leave the National in place until it becomes back-filled with honey. Strap it down, as the arrangement is inherently top-heavy.
