I put this brood box on the roof of my garage and a large swarm arrived a few days ago. My biggest problem was getting it down! I suffer from the most appalling vertigo! I had put some lemon grass oil on the entrance as its supposed to attract them. I transferred them into a nuc and just about managed to get them down. Its not something I would want to do every day of the week. 7 frames in all, at least. I have fed them and they seem to be settling in, I really must cross my fingers to get them through the winter, I have had such a rotten time with the bees this past couple of years.It seemed like a good idea at the time
