Re: Favorite swarm prevention method?
While there are many good suggestions above and I use several of them, there is one suggestion that has not been made yet can make a huge difference in swarming. Equalize the colonies. Presuming they are all disease free, swap frames of brood so that all colonies have roughly the same resources roughly 7 weeks before the main flow. They will then all be at roughly the same point 3 weeks later when you can pull a nuc or open the brood nest or whatever other control measure you choose to use. It is always easier to use the same manipulation on all colonies rather than having to figure out what each colony needs individually.
