A friend of mine in Minnesota has a hive that swarmed in late August. He caught the swarm and put it in an extra deep box with new foundation, but no built up comb.
The flow is done. The frost has hit.
Is there any sense in thinking about combining that swarm back into the original hive at this point?
I could see combining them back together (minus one of the queens) when there was still a flow, but now with no flow, I see no possible benefits of keeping that swarm. Combining the swarm back into the original hive at this point only makes me think of one word: Trouble.
Am I right? Kill off that swarm and put the equipment away and prep the original hive for winter?
