A friend of mine had a hot hive and apparently got them pretty riled up during an inspection. It got so bad he closed it up and went inside but the bees remained agitated. Jim also keeps purple martins and he noticed that the bees were flying into the wind (no small thing in this part of TX) and seeming to attack the martin house. This continued until dark, about three hours. The next day he took down the house to check on the nestlings that he had tagged just a few days earlier and found 16 dead. He has now moved the bees out of his yard and killed the queen and brood and will requeen today. Has anyone ever heard of such behavior from an aggressive hive?
