Stink bugs are a native of Asia and were accidentally introduced to the United States sometime in the late 1990s. Because there are no natural predators for stink bugs in the U.S., they have been able to spread rapidly to become a significant pest.
Exclusion is the best method to keep stink bugs from entering your home. Seal all cracks around windows, doors, siding, utility pipes, behind chimneys, and underneath the wood fascia and other openings .
Exterior applications of insecticides will help when sealing the exterior is difficult or impossible.
