Western yellowjackets are one of the most common wasps in Washington. These yellowjackets are small insects, usually measuring between 3/8 and 1/2 inch (10 to 13 mm). They sport a striking black and yellow coloration, with a distinct black band spanning across their abdomen, alternating with bands of yellow. Western yellowjackets have large compound eyes and delicate membranous wings, allowing them to forage and navigate your property with impressive precision.
Western yellowjackets are widespread throughout the United States and Canada, particularly in their native western regions of North America. These adaptable insects thrive almost anywhere, from urban spaces to wooden areas. You'll often spot them foraging for food near gardens, garbage cans, outdoor dining tables, and compost piles.
Western yellowjackets have a diverse palette, enjoying sweet treats like plant sap and nectar, human food scraps, and other insects. Eliminate these food sources by sealing garbage cans tightly and cleaning up any leftovers indoors and outside. As temperatures cool in the fall, yellowjackets become more aggressive, potentially leading to increased activity in these areas.
If you notice an influx of wasps around your home or yard, it could be a sign of a growing Western yellowjacket infestation. Because of their territorial nature, we suggest you contact a pest professional instead of tackling the problem alone.
