Did a cut out today. Found at least 25 swarm cells. All capped. Seemed like a lot of bees, maybe they hadn't swarmed yet. Anyway, was as gentle as I could be with them. Made two pretty full hives from this cut out. Saved 3 queen cells to make some swarm lure.
Question, I would like to wait till they hatch to punch them. If they don't, and are still in the larvae stage, will there still be pheromones?
