I need help here. I've got several hives on a friend's farm and got a call today saying that my bees are bullying the farm workers--4 stings now and they can't work the field near the hives. I've never had a problem with these hives before. Three days ago one of the hives swarmed. I caught the swarm and rehived them in the same beeyard.
I'm wondering if it's typical for the bees who stay behind and raise their new queen to become agressive until the new queen is properly established and laying in the hive? Do they become especially defensive during this short period?
I thought I'd close the hive off tomorrow and see if the trouble stops. If so I'll need to move the hive away until it's settled. Would two weeks be enough?
Any other thoughts?
Thanks in advance for any advice you can offer.
