With a crazy, busy summer, and also trying to be less hands on with the hives, I missed noticing that a hive got robbed. By the time I was able to get back to them, wax moths had settled in. After 7 years beekeeping, it's the first wax moth infestation I have had. It was like ripping fabric, as I pulled the frames out. What a mess. And I didn't realize how badly they will burrow into the wood as they make their cocoons. They messed up the frame rests.
