Yellowjacket Prevention and Control

A computer-generated image of the side, underground view of a yellowjacket nest. The entrance to the tunnel is at ground level, in between blades of green grass. The tunnel goes down into the brown dirt until it forms a large round space. Inside the space is the nest, which is connected to the wall of the hole by being connected to a root. The inside of the nest has dozens/hundreds/thousands of little cells for the queen yellowjacket to lay eggs in. The cells are surrounded by a covering that protects the nest. The nest can be entered through a hole in the bottom of the nest.

Yellowjacket Nest Treatment

The District provides no-cost control for ground nesting yellowjackets when the location of the nest is known. A yellowjacket nest site 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.

Dealing with Foraging Yellowjackets

Seeing yellowjackets and wasps around your yard does not necessarily mean that there is a nest on your property. Although there is no nest to remove, you may still be able to reduce the number of yellowjackets and wasps in your yard by removing what is attracting them there.
