I got a call Monday morning for a swarm that the homeowner noticed Saturday evening. By the time I got there Monday night, the bees were just falling from the swarm 1 by 1. Over a thousand bees had accumulated on the ground and roof. They were stumbling around and unable to fly. It did rain pretty hard on Monday as well. Has anyone ever seen this? How long can a swarm last? Could they be starving? The bees are 50 foot off the ground so I don't think they were sprayed by the homeowner.
