Sometimes they stay, sometimes they don’t
We had a swarm call. I grabbed my granddaughter and we went to the house. They told us it was in a tree over the carport near the front steps. I walked up the steps and didn’t see them. My granddaughter pointed to the tree and said, ‘they are right there.” She went to the truck, got the stuff and started to get the swarm. She was a bit too short to reach it so I helped her. We got them home on a Wednesday evening, on Sunday afternoon they swarmed and left the nuc. You win some, you lose some.
