The bee club helped me split some hives on the weekend with bought queens, and I brought one 10 framer to a new site in town on Sunday night. It was getting too dark and we thought we wouldn't worry about an entrance reducer. I checked today to make sure the queen had left the cage, and noticed dead bees on the ground in front of the hive. The odd bee was bringing in pollen and when I opened the lid I saw bees in the hive, but I didn't want to inspect so soon and disturb the new queen. I'll check again early next week. What could have killed the bees? I could only think it might be a robbing fight, or (I hope not) pesticide. Has anyone experienced this with a new split?
