Picked up a prime swarm yesterday from the front garden of a local house. Owners had lived there 25 years, and had always had bees "living under the floorboards of their bedroom". From outside, loads of bees coming and going from a hole next to the bedroom window. And another hole on another side of the house at upper floor level, again, loads of bees coming and going. Owners seemed happy to have them there. They said they swarmed every couple of years.
Anyway, bees landed on a baby cherry tree in their front garden. Popped them into a (14x12) nuc at about 2pm, then left until evening for them to all go in. Got back and they were all hanging off the front of the nuc. Hmmm. So, scooped them inside gently, waited for stragglers to go in (lots of bees fanning at entrance), wrapped them and took them home.
This morning, opened up the entrance (with queen excluder) and 30 minutes later, most hanging off the front of the nuc again, roaring away. So, maybe queenless?
Popped in a frame of BIAS from another nuc to see what they do with it. Also gave them an undrawn super as well, to keep them occupied. This evening, all bees back inside nuc.
