They’re back and they are everywhere. They don’t bite or sting or cause structural damage, but they sure are annoying. They are not native to this country (They are from China.) and have no natural enemies to keep their numbers down. They eat many plant species by plunge needle-like mouthparts into the leaves and sucking out the juice.
They enter homes in the fall through small cracks or openings around windows, doors, gable vents, chimneys, soffits, etc. to avoid the cold. Once inside, they keep active and make their presence hard to miss. In springtime, they emerge from their overwintering locations and venture outside to forage for food and mate. This is why you will often see stink bugs on or around windows.
For stink bugs that have invaded your home, read this for tips including sucking them into your vacuum, spraying the exterior of your windows and doors with 32 ounces of hot water and three-quarters of a cup of Dawn dishwashing liquid or making a call to a pest management professional.
