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. They are usually found in wall voids, attics, cracks and crevices in a building surface, and crawl spaces. The benefits are gained through various measures, such as increasing colony efficiency and establishing a female-based sex-allocation ratio. In the fall, the new queens begin hibernation, while the old queens die off and the colony collapses. Yellowjackets also go for fruit and human food, especially sugary drinks and meat. She creates a nest by chewing wood fiber into a pulp that is similar to paper. Yellowjackets may be confused with other wasps, such as hornets and paper wasps such as Polistes dominula. However, recent studies indicate that while worker reproduction occurs at a considerable rate, worker policing keeps these worker-laid eggs from reaching adulthood. The yellow and black coloring may appear similar, but paper wasps have more slender abdomens and longer legs that dangle down while they are in flight. [14], Female bee moths (Aphomia sociella) have been known to lay eggs in the nests of V. germanica.
