Boxelder Bug

Found primarily on female boxelder trees, but also maple and ash trees. Often congregate on the sunny sides of buildings.

Herbivorous, primarily feeding on the seeds of boxelder trees and occasionally the juices of leaves or soft seeds from other trees.

Diurnal insects that aggregate in large numbers in autumn to find warm overwintering sites. They undergo incomplete metamorphosis (egg, nymph, adult).

Harmless to humans and pets as they don't bite or sting. They are considered a nuisance pest when they enter homes; however, they do not cause significant damage to properties or healthy trees.
