As summer gives way to fall, many homeowners notice an unwelcome visitor appearing on windows, walls, and ceilings: the brown marmorated stink bug.
While stink bugs don’t bite, sting, or damage your home like termites or rodents, they can quickly become a frustrating nuisance. Once they find a way inside, they often gather in surprising numbers, making it feel like your home has become their winter retreat.
The good news? A little prevention before cooler weather arrives can go a long way toward keeping stink bugs outside where they belong.
Why Do Stink Bugs Come Inside?
Stink bugs aren’t looking for food when they enter your home.
They’re looking for warmth.
As temperatures begin to drop in late summer and early fall, stink bugs search for protected places where they can spend the winter. Homes, garages, sheds, and commercial buildings provide the perfect shelter.
They commonly enter through:
- Gaps around windows and doors
- Cracks in siding or foundations
- Utility openings
- Roof vents
- Chimneys
- Damaged screens
Once inside, they typically hide in attics, wall voids, crawl spaces, or other quiet areas until warmer temperatures arrive.
Why Are There So Many at Once?
Unlike ants or termites, stink bugs don’t reproduce inside your home.
Instead, many stink bugs are attracted to the same warm structure at the same time. Sunny exterior walls, especially on the south and west sides of a home, naturally attract them during the fall.
If they discover even a tiny opening, dozens or even hundreds may follow.
That’s why homeowners often notice several stink bugs appearing indoors over the course of weeks or months.
Are Stink Bugs Harmful?
Fortunately, stink bugs are more annoying than dangerous.
They don’t:
- Bite people
- Sting
- Damage wood
- Spread diseases
- Reproduce indoors
However, they do have one famous defense mechanism.
When crushed or disturbed, stink bugs release a strong odor designed to discourage predators. That’s why squishing them usually creates a bigger mess than simply removing them.
The Best Way to Remove One
If you find a stink bug inside your home, avoid crushing it.
Instead:
- Gently capture it with a tissue or cup.
- Vacuum it if you have only a few.
- Dispose of it outside or into a sealed trash bag.
If you’re vacuuming several stink bugs, empty the vacuum promptly to help prevent lingering odors.
Prevention Is Much Easier Than Removal
The best time to deal with stink bugs is before they move inside.
Professional exterior treatments during late summer and early fall help reduce the number of stink bugs gathering around your home before they find a way indoors.
Homeowners can also reduce the chances of an infestation by:
- Sealing cracks around windows and doors
- Repairing damaged screens
- Caulking gaps around utility lines
- Installing weatherstripping where needed
- Closing openings around vents and soffits
These small improvements not only discourage stink bugs but can also help keep other seasonal pests outside.
Why Professional Treatment Makes a Difference
Many homeowners try to spray stink bugs after they’ve already entered the house.
Unfortunately, by that point, many more may already be hiding inside walls or attics.
Professional exterior treatments focus on the outside of the home before stink bugs gain entry. By treating common access points and problem areas, technicians help reduce the number of insects attempting to move indoors.
This proactive approach is often far more effective than reacting after the invasion has already begun.

As temperatures cool, homeowners also begin seeing increased activity from:
- Mice
- Rats
- Spiders
- Boxelder bugs
