Bees swarming is a natural occurrence most often occurring in spring and in summer. Bee swarms are identified by a mass of bees clustered on a post or hanging from a tree or some other structure and looks like a live bunch of grapes. The bees may stay in this cluster for a few minutes up to a few days while they look for a new home.
Swarming bees typically are not dangerous if they are left alone. Bee swarms are simply in transit looking for a new home and should only be handled by an experienced beekeeper or swarm collector. You may get stung if you attempt to spray them with a hose, smoke or insecticide.
Remember the important role bees play in fertilizing many of our nuts, fruit and vegetables. One in every three bites we eat we owe to the work bees do to pollinate plants. Why not try to contact a beekeeper to have the swarm removed and placed in a beehive.
