All the bees in one of my top-bar hives died outside the hive entrance. There are essentially no dead bees inside the hive.
A few weeks ago, I noticed lots of bees dead on the ground just outside the hive entrance. At that time, other bees were sort of twitching around on the ground. Now they're all dead.
I have 4 other top-bar hives and 4 Langs in the same yard, and all the others seem fine.
1. Anyone know what could cause this behavior and the end result?
2. Do you think it's safe to reuse all the comb from this hive?
