Pest Identification: Paper Wasps

Paper wasps are slim, yellow-and-brown, like yellow jackets, with nests often found in residential yards. Different species may have varying colors and markings. Signs of infestation include the physical sighting of nests and wasps around them.

Preventing infestations involves checking plants for nests before trimming, sealing cracks, repairing screens, and keeping doors closed. Covering food outdoors, avoiding strong fragrances, wearing protective shoes, and being cautious during outdoor activities help reduce the risk of stings. Paper wasp stings can be painful and may cause allergic reactions; immediate cleaning, elevation, and using OTC medications can help alleviate symptoms.

Paper wasps eat nectar and insects, building umbrella-shaped nests in spring. Nests are constructed from tree bark pulp and hang from various structures. While not aggressive, paper wasps may sting when disturbed. Impregnated paper wasps rarely sting. Most colonies die after the first freeze, with hibernating queens living just over a year. Abandoned nests deter new colonies.

Key Facts:

Paper wasps are not typically aggressive unless disturbed.
They are attracted to sugary foods, perfumes, and flowery scents.
Professional removal is advised if nests are in high-traffic areas.
Abandoned nests serve as a natural deterrent.
Wasps are beneficial pollinators and control garden pests.
Queens start building nests in spring, continuing until late fall.
Unlike honeybees, wasps can sting repeatedly without dying.
They make nests from tree bark pulp, regurgitating it to create papery structures.
