The brown marmorated stink bugs first arrived from Asia in 1996 and have become an increasing nuisance for homeowners in the Eastern U.S. Named for the “stink” they emit as a defense against predators, stink bugs are especially unpleasant to find indoors.

Stink bugs have the potential to spread throughout the country, which could be harmful to the agricultural industry. Although these smelly pests do not pose serious property or health threats to homeowners, their tendency to invade homes in high numbers can be a nuisance. Adult stink bugs enter homes and other structures in the late fall to seek shelter from the winter weather. They reemerge from overwintering sites in early spring and try to exit, but sometimes enter living spaces instead. Like other overwintering insects, they often congregate on the sides of buildings.
