We cannot provide control of aerial yellowjacket nests or other wasps nesting on or inside structures. These wasps can become a nuisance around our homes, gardens, pools, orchards, and parks. They can also pose a health hazard, especially for those who are allergic to their venom.
Some species attach the nest to trees, shrubs, or buildings.
Native pest species usually construct nests underground, often in old rodent burrows and ground holes. These wasps can be observed returning food to the colony as they enter a hole in the ground. Nests are constructed from paper. Yellowjackets make a pulp by gathering wood or plant fibers, chewing it up and mixing in some of their own saliva. When the pulp is spread out it dries to form paper.
