It’s springtime and that means bees are on the move. According to the UC Davis Statewide Integrated Pest Management Program, warming temperatures prompt a queen and a group of worker bees to leave their original colony in search of a new nesting location.
The sight of a large number of bees flying by can be scary, but experts say spring honey bee swarms are typically docile. The swarm may rest on a tree limb or other location where most of the bees will remain, while several scouts continue the search for a suitable nesting location.
Swarming honey bees have been known to leave their temporary resting point after just a few hours or even a few days. It’s best to leave the bees alone, and soon they will be off to their new nest.
In cases where the swarm has stopped at a location that is potentially problematic including a school or a park, Contra Costa County citizens can contact the District for very limited services focused on inspection and assistance. The District may treat bees that are a threat to people in public areas. The Mt. Diablo Beekeepers Association can also be an important resource for bee swarms, particularly those on private property. Beekeepers will often remove the bees and relocate them to a hive where the bees can have the new home that prompted their swarm in the first place.
