Re: Wax moth and wax moth larvae
I think location is key but I'm speculating. Here in New England, we tend to get pretty cold winters although we've had some recent exceptions which created wax moth problems for me. I see wax moths in struggling or doomed colonies and I see them in deadouts if I leave the comb out too long. The only other time I've seen wax moths in a strong colony was a hive with three mediums with only the top two covered with brood. The bottom medium was virtually empty of brood but was harboring wax moths. The colony was pretty strong and had two mediums of honey over the brood boxes. It seemed the bees moved up as the year progressed and as I added boxes and the moths took advantage of the bottom, sparsely populated box. Again, the cold winters here seem to knock the moths down a bit and they get going again about the same time the colonies get built up. Until recently (my mistake) I had been spraying comb to be stored with BT and maybe that treated comb, once it's back out in the yard, offers residual protection to augment the natural activities of the bees. Again, just my thoughts.
