please give me any advise for the last week from 3 of my hives the bees are in a swarm but they keep coming back to the hive .WHAT IS THE PROBLEM?
Well, have you looked at them to see what is going on? There are such things as false swarms, but they usually precede the real thing by only a few days. Do you mean that thousands of bees pour out of the hive at once, then their excitement subsides and they are returned to the hive a couple of hours later? We always called them false swarms and it usually meant that the queen wasn't quite ready to fly. On a few occasions they never did swarm, but most of the time a swarm would erupt 3-5 days later.
Probably it is not a swarm, because swarms come back at the hive when the queen canÂ´t fly (if you have cut a wing).
If your bees are flying in the evening around the hive perhaps are cleaning the intestines.
