Brown Marmorated Stink Bugs and How to Deal with Them

The brown marmorated stink bugs might sound dangerous and scary but they are not harmful to you, your children, your home or your beloved family pet.

An adult brown stink bug has a shield-shaped appearance, typically 5/8” long. That’s about the size of a U.S. dime. You might have seen the dark, mottled brown stink bugs hanging around your home, but there are also green ones with white specks and the brown and cream critters with black and white banding exposed on the abdominal edges.
