Stink bugs typically enter a state of dormancy called diapause in winter. Unless, of course, they can find a heat source to sustain them. If they do find a heat source–say your home–they can remain active all year. Any stink bugs in your home will seek hiding places to wait out the winter. They’ll almost leave you alone… but the smell might not.
Obviously, nobody wants stink bugs in their house in winter, but how do you get rid of stink bugs? Especially if you have an infestation? And what draws them to some buildings over others? Here’s how you can find (and remove) stink bugs in your home this winter:
Signs of Stink Bugs in Winter
To tell if you have a stink bug infestation, look for these signs that they may be nearby:
- Live bugs. Stink bugs’ bodies are brown or black and shaped like a shield. They have spots of lighter coloring around the edge of their body, six legs, and antenna. If you see one, then there are almost certainly more nearby. If you see one moving around inside your home, then you probably have an infestation.
- Dead bugs. Pay attention to the entry points in your home, including door frames, windows, and baseboards. Stink bugs congregate around heat sources, especially in fall and winter. When they find cracks and gaps around these heat sources, they push and squeeze their way through. Sometimes, not all the bugs will make it all the way through. You might find the bodies of less-fortunate members of the party around door and window frames, baseboards, and utility lines.
- Stink. Stink bugs… got their name for a reason. When they feel threatened, these bugs secrete a foul-smelling liquid in defense. If you smell a pungent odor like rotten vegetables or cilantro, it may be a stink bug. Stink bug liquid secretions are a pale-yellow color and can stain surfaces over time. They also use this scent to attract others when to sources of food and shelter.
Why my home?
Stink bugs come into homes looking for shelter, water, and food. Their preferred food source is sugar and they’re fond of overripe fruit. They’ll also congregate around the food waste in trash cans or beneath cupboards and the dishwasher.
Sugar isn’t the only stink bug draw. They also gather around light and other heat sources. They’ll be particularly noticeable at night, when you’ll see them scurrying around outdoor light bulbs or indoor lamps. Food or heat sources could be reasons why you have a stink bug problem.

How to Prevent Stink Bugs
Keep stink bugs from bothering your property by taking some of the following steps:
Keep stink bugs from bothering your property by taking some of the following steps:
- Minimize outdoor lighting. Don’t keep any outdoor lighting on unless it’s necessary. The more bugs your lights draw to the surface of your home, the higher the odds that at least some of the congregation will find its way inside.
- Rub your window screens with dryer sheets. This sounds weird, but it’s an easy prevention tactic. The fragrance of your average scented dryer sheet is unpleasant to a stink bug. Rub them on your window screens when doing regular cleaning as a simple exclusion effort.
- Fix plumbing leaks. Stink bugs are drawn to moisture they can access without drawing attention to themselves. This is most easily found near hidden plumbing leaks in faucets and pipe joints and under counters and cabinets.
How to Get Rid of Stink Bugs
Stink bugs will usually naturally leave your home in spring when they re-emerge from dormancy. We recommend leaving the cracks and crevices where they might enter diapause in your home alone until then. If you seal up their hiding places, stink bugs will die inside your home. When stink bugs die, they secrete their odor–which contains a pheromone that attracts more stink bugs. They also secrete this odor when you crush them or when they find good hiding places.
If you notice active stink bugs inside, vacuum them up (don’t crush them!). Dispose of the vacuum bag outside of your home. Whenever you remove bugs from a surface, clean that surface with ammonia and/or soapy water. This will help remove pheromone secretions and keep more the bugs away. Focus on exclusion methods until you’re sure all the stink bugs are gone. If you trap or kill too many of the bugs, it’ll only exacerbate your problem.
