Boxelder Bugs commonly form large congregations alongside homes,on trees and especially near Boxelder bushes. They also prefer the warm and sunny sides of buildings. Females will overwinter inside walls and lay eggs on leaves in the spring.

Boxelder Bugs are not harmful to humans, but they will secrete a staining dye if crushed. If they are found indoors, it is best to remove them with a paper towel, or vacuum cleaner with its hose attachment, to avoid creating a mess. They do not emit any odors.

The Boxelder Bug can be found in parks, gardens, meadows, fields and forests. Adults, their larvae and their growing nymphs drink the sap from flowers, trees and other plants, but rarely with enough vigor to destroy them. The feeding may slightly deform fruits.
