I put out 5 frames of deep brood combs to spray with BT and before I got back to do it, there were lots of bees cleaning up some nectar in the comb. So I left it for them and brought them in at dark (bears!). I went to spray them today and I found 3 wax moths alive in the Jester box with the combs. I can't see any eggs, but to be on the safe side, I put them in the freezer and will try to spray them in a few days. So, beware, despite some nights below freezing, they are still active. Sneaky too. J
