Hives 3 and 4 No More
It was nice while it lasted. The Langstroth never really did grow well but lasted into July. I swapped the sealed bottom board and top entrance for a bottom entrance and a few weeks later the hive was empty. There were some SHB, but not the devastation that I saw in the past. The TBH did thrive in the 15 inches or so near the entrance. I checked the hive before scout camp and drilled some drainage holes in the back of the hive. After scout camp the bees were gone.
Thus ends the third set of hives.
