I placed a swarm trap with an old piece of comb inside my backyard. I really wasn't expecting to catch any there and I was going on vacation so I just left it there. After 12 days I returned home and I saw bees going in and out. Excited and being a newbie, I suited up to go check out the box. What I found was only about 50 or so bees and no queen. The bees seem to be repairing the old comb, which had wax moth damage. But it is very strange, nothing else seems to be going on, but after 3 days there is still a lot of flying in and out of the entrance, but no swarm. Could they just be robbing the old comb? Or do scout bees prepare a place ahead of swarming? Someone at my bee club suggested that these bees were the stragglers from a swarm I missed while I was gone. Any Ideas?
