Bald-faced Hornets (6521)

Bald-faced hornets are black and white yellow jackets, and are 5/8# to 3/4# long. They build the typical sphere-shaped, gray paper "hornet nests". The nests may be built on shrubs at ground level or 60 feet or higher in trees. Nests may also be attached to sheds, houses, or utility poles. The nests are annual and not reused the following season. Baldfaced hornets are beneficial because they feed on many pest insects. If the nest is close to a walkway or where the hornets become a problem, control may be needed. Locate the entrance to the nest during the day. Control should be done at night when most of the hornets are in the nest. Do not shine a flashlight directly on the nest, as this may attract the hornets toward the light after being sprayed. Use a commercially available wasp and hornet spray directed at the entrance hole, and follow the label directions carefully.
