Adoption is a result of three situations: when queens lose their nests and "make the best of a bad situation"; workers leave multiple-foundress nests; and subordinates employ a "sit-and-wait" strategy, waiting for nests to be abandoned. Nests are orphaned when the adult wasps die while taking care of their nest, leaving an immature brood.
Before you attempt to get rid of a wasp’s nest, consider whether the wasps are an actual nuisance. If the nest is in a highly trafficked area of your lawn or an area where your pets or kids play ...
Are all wasps aggressive? Are their stings dangerous? Know these facts before your next encounter.
If there is an ant attack, nest abandonment is easier and allows for a more rapid escape due to the fact that the wasps do not build envelopes over their nests. In addition, these wasps possess a gland located in the VI abdominal sternite (van de Vecht’s gland) that is primarily responsible for making an ant repellent substance.
Polistes is a cosmopolitan genus of paper wasps and the only genus in the tribe Polistini. Vernacular names for the genus include umbrella wasps, coined by Walter Ebeling in 1975 to distinguish it from other types of paper wasp, in reference to the form of their nests, [3] and umbrella paper wasps.

All species of social wasps construct their nests using some form of plant fiber (mostly wood pulp) as the primary material, though this can be supplemented with mud, plant secretions (e.g., resin), and secretions from the wasps themselves; multiple fibrous brood cells are constructed, arranged in a honeycombed pattern, and often surrounded by ...
Wasps are looking for large bodies of water such as pools and ponds to cool themselves down, “which makes them seem more present” compared to past years, Kimsey told The Sacramento Bee.
Female worker wasps infected with X. vesparum appear to have their behaviour modified because they act as if they are future queens and cease working, abandoning the nest before the uninfected future foundresses and males do, and form aggregations outside of the nest. When the uninfected future queens leave the nest to go to these mating ...
