The District provides control for ground nesting yellowjackets when the location of the nest is known. There are a number of other insects that are sometimes confused with yellowjackets. The information below describes the differences between these insects and the reason the District does not control them.
Aerially nesting yellowjackets and wasps are considered beneficial insects. They eat spiders and other insects, and do not generally cause harm to humans.
Bees are considered beneficial insects. Solitary, native bees are also beneficial and do not usually need to be controlled. If you find a honeybee swarm and would like it removed, please contact the Beekeepers’ Guild of San Mateo County; these bees are a domestic species and can usually be given a safe new home with a local beekeeper.
