Welcome to Washington wasps where northern giant hornets might or might not be eradicated in the state, Nonetheless, the efforts of citizens and scientists continue to work to make it a reality.
Apart from the potential agriculture harm inflicted by the northern giant hornets, the Washington wasp world also remains aware of both the benefits and potential harms caused by the hundreds of native wasps in the state.
The vespids, yellow jackets and paper wasps, can be fairly easy to identify. Concerned residents need only know species and their nesting behavior to take preventive action if necessary.
Fortunately, species identification can be relatively straight forward.
The picture at the top of the page, for example, shows European paper wasps tending their umbrella shaped nest.
Common Aerial Yellowjacket Nest
Bald-faced Hornets – aerial nests
Blackjackets – ground nests
Prairie yellowjacket – red arrow points to circular spot – ground nests
Western Yellowjacket – red arrow points to anchor spot – ground nests
Potter and mason wasps fit into the vespids family. However, their presence does not create a similar stinging and medical conundrum. They are solitary wasps that help with natural pest control.

Hairless and small in size, Cuckoo Bees family resemble wasps more than they resemble bees, making them among the least known of the family.
The common name cuckoo refers to the bee’s practice of brood parasitism, like it’s namesake in the bird world, the Cuckoo bird. Adults lay their eggs in ground nests of other bee species, and then let the young fend for themselves.
