Hi! sorry if this is a silly question. I just installed my first colony today and noticed that a lot of the bees were hanging out on top of the top bars. My roof is very tight fitting and my concern was that some of the bees will get trapped in between the top bars and the roof or crushed when putting the roof back on. right now I have it propped open, but my worry now is that they will build comb inside the roof. should my roof have a very tight seal? if so, how do I keep the bees out of that space? Should I just be brushing them off our should there be a gap for them to escape?

If you follow my design, there is a gap deliberately left on either side, so that bars will not be dislodged when removing and replacing the roof. So no, it should not be a tight fit.

Also, I recommend a gabled roof, so you have space to add insulation and a feeder, if needed.

We did use your design, but I'm not sure if my husband deviated at all. It isnt tight on the top bars, or even touching them. It's just tight around the box. Doe that gap allow for the bees to escape if they get trapped under the roof? If not, How do I keep them out of there?

I'm not sure if that was clear... I was having trouble getti.g them to go down into the hive and a lot of them ended up on top of the top bars. The roof is indeed gabled.

The gap allows bees in and out of the roof space. If you have all your bars pushed tight together, they would normally show little or no interest in going in there. In any case, you should keep some insulation on top of the bars at all times.

On a side note in the winter the wood tends to expand as it draws in moisture so its best to have a slightly loose fit otherwise it can get stuck on! I usually have about a 10-15mm gap on the length. But either side of the top bars I have about a 20mm gap so as not knock them when replacing roof and also allows for bees to escape and air to circulate a bit in case of hot weather.

The wood does expand (and contract) with changes in humidity, however whether this happens in winter or some other season depends on where in the world you are. Here in the central U.S. the humid season is spring and summer and wood contracts in winter.

How much of a gap is okay between the roof gables and the bar ends? Is a few inches a problem?

Only a problem if the wind can blow up through the roof area - but why would you want such a large gap?

It's not that I "want" such a gap, it's just that's how my cover wound up being, as I muddled through constructing it. I'll close it in a bit, just to make sure. It looked suspicious to me. Thanks for the reply.

Conserving wild bees

Research suggests that bumble bee boxes have a very low success rate in actually attracting bees into them. We find that if you create an environment where first of all you can attract mice inside, such as a pile of stones, a drystone wall, paving slabs with intentionally made cavities underneath, this will increase the success rate.

Most bumble bee species need a dry space about the size a football, with a narrow entrance tunnel approximately 2cm in diameter and 20 cm long. Most species nest underground along the base of a linear feature such as a hedge or wall. Sites need to be sheltered and out of direct sunlight.

There is a spectacular display of wild bee hotels here
