A co-worker in our office captured an exciting event on her backyard fence last night – a honey bee swarm. Sometimes honey bee colonies send off swarms with one queen and several thousand workers. This a natural event for honey bees. Typically bee colonies trigger a swarm when the colony is overcrowded, usually in early summer. This swarm is moving to a new site a little later in the season.
During the move to a new site, the queen bee will select a place to rest while scouts look for a new home. She’ll choose a fence, tree branch or even a spot on the ground. While the queen rests, the worker bees cluster around her. The swarm stays clustered around the queen until scout bees chose a permanent site for their colony. This may take a a few hours or a couple of days. Once the site is chosen, the swarm quickly breaks apart and leaves. (This is a good time to remind everyone to make sure your home doesn’t have any gaps or cracks where the scout bees could move the colony. Seal and caulk these openings immediately.) Continue reading
