Paper Wasps

What are Paper Wasps?

Paper wasps are a type of social wasp belonging primarily to the genus Polistes. They are known for their distinctive, open, umbrella-shaped nests made from chewed wood fibers mixed with saliva, creating a paper-like material. These nests are often found in sheltered areas like under eaves or in trees. Paper wasps have a slender build with brown, yellow, or reddish markings and are generally less aggressive than other wasps, such as yellowjackets. The colony consists of a queen, sterile female workers, and males, with the queen surviving winter to start a new colony each spring. Adult paper wasps feed on nectar, while their larvae are given chewed-up insects, making them beneficial for pest control. They communicate through chemical signals and can even recognize individual faces within the colony. Despite their ability to sting multiple times when threatened, they play an essential role in the ecosystem by managing insect populations and aiding in pollination.

Where do paper wasps build nests?

Paper wasps build their nests in sheltered locations that provide protection from the elements and predators. Common sites include the undersides of eaves, roof overhangs, attics, and the corners of windows and doors. They also nest in natural settings such as tree branches, shrubs, and under large leaves. The nests are constructed from a paper-like material made by chewing wood fibers mixed with saliva, resulting in an open, umbrella-shaped structure with exposed cells for their larvae. The preference for these locations is driven by the need for a stable environment to rear their young and ensure the colony’s survival through varying weather conditions. The strategic placement of nests in these sheltered areas helps paper wasps maintain an optimal temperature for their developing brood and reduces the risk of damage from rain or wind.

How do you get rid of paper wasps?

To get rid of paper wasps, it’s essential to approach the task carefully due to their ability to sting. The best time to remove a nest is at night when the wasps are less active. Wearing protective clothing, such as gloves and long sleeves, is advisable. Commercial wasp sprays are effective; they should be used from a distance and directed at the nest’s entrance. After spraying, wait at least 24 hours to ensure all wasps are eliminated before removing the nest. For a natural approach, a mixture of water and dish soap can be sprayed on the nest to clog their breathing pores. Prevent future nests by sealing entry points around your home, removing potential nesting sites, and using wasp deterrents like decoy nests or plants that repel wasps. If the nest is in a hard-to-reach area or if you’re allergic to stings, it’s best to contact a professional pest control service.
