The District provides control for ground nesting yellowjackets when the location of the nest is known. A yellowjacket nest looks like a small hole in the ground with many yellowjackets flying in and out. Without disturbing the nest, mark its location with a flag or other object so that the technician who comes to treat it will be able to find it.
Aerially nesting yellowjackets and wasps are considered beneficial insects. They eat spiders and garden pests, and do not generally cause harm to humans. These nests should only be removed if they are in a location that will be disturbed by people or pets.
