I have a colony I started 2 yars ago near my house that has become aggressive so I moved it about 300 yards away. I put a large branch in front of the opening so the bees would re-orient to their new location and everything seemed to go fine, but now 2 days later I notice a small swarm of bees on a bush next to the original location and they are not happy! I assume these are just misplaced bees and there is no queen involved. How long will they stay there and will they find their way back to the hive?
