The bald-faced hornet is a relative of the yellowjacket and gets its common name from its largely black color and mostly white face. This stinging insect is named a hornet because of its large size and aerial nest.
Bald-faced hornets are social insects, although not true hornets. They live in colonies that may contain between 100 and 400 members at their peak. They usually appear in late summer when populations are largest. Unlike other stinging insects, bald-faced hornets do not reuse their nests season after season.
Bald-faced hornets build paper nests at least three or more feet off of the ground, usually in trees, shrubs, on overhangs, utility poles, houses, sheds or other structures. These nests can be as large as 14 inches in diameter and more than 24 inches in length.
