I had a small hive from a recent swarm, that today, went over the edge of controlling SHB. I did save this hive but a few frames did sign of larva rummaging through the goods. I did not smell the obvious yeast smell yet. I stuck these frames in the Bee freezer for a enjoyable SHB freeze out! My question, what is a safe time of freezing and killing these buggers before I can remove these frames for the gift of community robbing?
