It's better, says Art, to notify a beekeeper who can remove the bees when they are still in the swarm. There are various ways to retrieve fresh swarms. It's not a difficult job but not one for the typical homeowner, says Art. He recommends that you not agitate the bees. Spraying them with an insecticide or diesel fuel ruins the beekeeper's chance of starting a healthy hive after removing the bee swarm from your property.
Swarms look like a moving, live, fuzzy brown ball hanging on a bush or limb.
They can be as small as a softball or as large as a basketball. If you see a swarm, contact a local beekeeper or your closest extension agent.
