Stink Bugs

Stink Bugs, known for the unpleasant odor they produce, are native to China, Japan, and Taiwan.  Their introduction to the United States was accidental, with the first specimen being collected in 1998.  Historically, they are an agricultural pest and are a rising threat to our orchards, fruit farms, and vegetable farms.  For homeowners, their size and pungent smell make them an unwelcome nuisance, especially when their numbers get out of control.


Stink Bugs find their way into our homes through small cracks and openings around windows, doors, and underneath loose exterior siding panels. They spend the winter hiding inside the walls, the attic, or the crawlspace until the spring when they become visible in our homes. Inside the home, common places to find Stink Bugs are on walls, windows, and curtains. Outside, they are frequently found on the sunny sides of home exteriors.

What's That Smell?

The unpleasant smell from Stink Bugs comes from a gland along their abdomen that produces a pungent smelling chemical (some describe this as smelling like coriander).  Some Stink Bugs are capable of spraying this chemical several inches when they are threatened.

Detection & Prevention

To keep Stink Bugs out of your home and property, inspect the exterior of your structure frequently, especially in the fall when Stink Bugs will seek out their overwinter homes. Make sure your exterior siding is secure and caulk and/or fill your windows, doorways, and other areas where there can be small cracks and crevices.

During the winter, detection is very difficult as Stink Bugs do not feed or reproduce. On warm days in winter or later in spring they will become active and you will find them on walls, curtains, and windows, seeking the warmth of the outside.  In summer, when Stink Bugs reproduce, problems can quickly escalate.  Infestations can reach hundreds and literally cover the warm exteriors of your structure.  When this happens, it is best to call a professional.
