Yellowjackets typically nest in a variety of concealed and protected locations, both underground and above ground:
- Underground Nests: Most commonly, yellowjackets build their nests underground in abandoned rodent burrows or gopher holes. These nests can also be found in other underground cavities such as utility vaults or hollow spaces beneath the soil
- Above Ground Nests: Some species, like Dolichovespula (aerial yellowjackets), build exposed aerial nests in places such as tree cavities, attics, eaves, wall voids, or dense vegetation. Nests can also be found in wood piles, hollow logs, tree stumps, or inside structures like attics and walls
- Other Hidden Spaces: Yellowjackets may also nest in less obvious locations like recycling bins, railroad ties, concrete blocks, or dense vegetation like ivy and Italian cypress
In summary, yellowjackets prefer sheltered, hidden spots with limited accessibility, often underground in abandoned burrows or in enclosed spaces above ground such as attics, walls, or dense vegetation. The nests are made from chewed wood fibers, forming a paper-like material, and typically have a small entrance hole
