I moved a large swarm from a trap into a deep today.... And just now three hours later came back to get rid of the trap and put it away thinking all stragglers would have made their way to the box .... There were like 10 bees left in the trap huddled in a corner and as I shook them out 5 small hive beetles came pouring out of a crack in the bottom of the trap the bees were guarding so I got to play whack a beetle and killed them all but it was interesting to see the hive beetles corralled by the bees in the trap and the bees refusing to follow the queen to the new box and let them loose... Something new every day.
