A nucleus split is the simplest swarm control in this book, and the only one that leaves you owning more bees than you started with.

Pull a few frames of brood and their attending bees out of a crowded colony, along with either a ripe queen cell or a mated queen, and move them into a small box of their own, a nucleus, or nuc.

The parent colony loses enough population and brood to relieve its congestion, often enough to cancel a swarm already in motion. The nuc, meanwhile, is a genuine new colony, small but complete, that will grow into a full hive over the following weeks if the weather and forage cooperate.
