What do stink bugs look like?

Just look for bugs with triangular shaped plates on their backs and you’ll see what stink bugs look like. Because of this plate, they’re also called shield bugs. Stink bugs are referred to as stink bugs because of a gland found on their thorax that allows them to release a very foul smelling odor to help deter threats.

Adult stink bugs are mottled grayish brown in color and grow to about ¾ of an inch in length; their body is basically as wide as it is long.

Are stink bugs dangerous?

Stink bugs are invasive but they are not dangerous to people; they do not bite or sting and aren’t known to cause any health threats to people. Stink bugs are a major agricultural pest and have the ability to cause a lot of damage to plants and crops.

Inside of a home stink bugs don’t cause structural damage but they have the ability to damage houseplants.

Why do I have a stink bug problem?

During the spring, summer and early fall stink bugs live happily outside, but as the weather cools they begin to congregate on the warm sunny sides of homes and other buildings. As they crawl up the exterior the find their way inside through cracks in the siding, spaces found around windows and doors, vents, and holes in the soffit.

Once inside you home they will travel through it in order to find a warm safe spot to overwinter inside of. Stink bugs often overwinter behind wall voids, underneath of floors, behind crawl spaces, and in attics.
