Bald-faced hornets are social insects, although not true hornets.
They live in colonies that may contain between 100-400 members at
their peak. They usually appear in late summer.
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. They are found throughout
the United States, Canada and north into Alaska.
Bald-faced hornets are aggressive and will attack anyone or
anything that invades their space. This makes bald-faced hornet
removal somewhat difficult. They have smooth stingers, so they can
sting over and over again. Their stings also carry venom that makes
the stings hurt, itch, or swell for about 24 hours. Humans are at
the same risk of allergic reactions from a Bald-faced hornet stings
as with other insect stings.
