These larvae are the first batch of workers. Trapped yellowjackets are likely to chew right though drywall and end up in a living space. The queens have compounds that act as a kind of antifreeze in their blood, which enables them to survive the cold temperatures that kill the rest of the colony. [5] The same kind of nest expansion has occurred in Hawaii with the invasive western yellowjacket (V. [10], V. germanica wasps have a diverse diet. It was probably introduced in the late 19th century, but did not appear in large numbers until around 1940.

The queen bee lays all of the eggs in a colony. A significant portion of nests are found in artificial structures such as attics, and a small portion are found above ground.
