What about SPM {swarm prevention management} or do you all just let them swarm ?
Can't get any real honey that way.
It really depends on what you do with the swarms you catch. They need not be used to start a new hive. They are very effective in strengthening an established hive that is either not strong enough or that needs to have its queen replaced.
Often I will take two or three swarms and unite them to make one strong hive that will produce an abundant crop in its first season.
The easiest uniting is done by the newspaper method.
The excess queens can be used in replacing other old ones or (after mating, if not mated before swarming) held in a queen bank for later use.
What I'm trying to say is that, beyond the pure pleasure of capturing swarms, when managed properly, they can be a real blessing for the beekeeper.
The one bad side to counting on capturing swarms is that they don't always get caught, and then you're in a pickle, busy cursing yourself for not having managed your bees in a way that prevented the swarms' moving out from your hive.
