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
Bald-faced hornets are aggressive and will attack anyone or
anything that invades their space. This makes bald-faced hornet
removal somewhat difficult. These hornets have smooth stingers, so
they can sting over and over again. Bald-faced hornet stings also
carry venom that makes the stings hurt, itch and swell for about 24
hours. Humans are at the same risk of allergic reactions from
bald-faced hornet stings as with other insect stings.
