I had a swarm move into a dead hive of mine, that had been infested w/ wax moth. I opened it up to swap out some frames - but this is a big swarm, and they were pretty much covering all the frames, hard at work cleaning up things. Should I let them clean it up? Or should I plan on a day of brushing them off, and put in new frames? Never had to deal w/ this before. Thanks.
Let the bees clean it up. They will do it better than you can.
