Wasps nesting around homes are a common concern for many homeowners, but not all wasps pose a threat. According to Kansas State University entomologist Raymond Cloyd, many wasps play a beneficial role in the ecosystem by preying on caterpillar pests. Most are relatively docile and only sting when provoked.

Mud daubers and paper wasps are frequently seen around homes and are unlikely to attack people. In contrast, yellow jackets are more aggressive and known to sting unprovoked.

While wasps can be helpful, their presence near outdoor spaces can raise safety concerns. Homeowners considering nest removal should first determine whether the nest is new or mature. New nests are smaller and contain fewer wasps, making them safer to remove. Wasps also typically do not rebuild in the same spot once a nest has been physically removed.

If insecticide is used, it should be applied at night when wasps are inside the nest. Large, established nests should be handled by a pest management professional. For proper identification, contact a local K-State Research and Extension office with a description or photo.
