Stink Bugs in North Carolina: Why They Appear in September and How to Keep Them Out

As September arrives in North Carolina, cooler evenings bring a welcome break from the summer heat. Unfortunately, this shift also signals the start of a different kind of season—stink bug season. These pests often show up in large numbers during early fall, clustering around windows, doors, and siding as they search for a warm place to spend the winter.

While stink bugs don’t bite, sting, or spread disease, their presence can still disrupt the comfort of your home. The good news? With the right prevention and care, you can keep them outside where they belong.

Why Are Stink Bugs Active in September in North Carolina?

Stink bugs, especially the brown marmorated stink bug, are common throughout North Carolina. Their seasonal behavior makes them more visible this time of year:

Changing Temperatures: As the nights cool, stink bugs look for warmth. Your home becomes an inviting shelter.
Overwintering Habits: Unlike mosquitoes or flies that fade with the season, stink bugs survive the cold months by hiding inside walls, attics, and basements. September is when they begin the search for those hiding spots.
Attraction to Light and Heat: Stink bugs are naturally drawn to sunny spots on homes, especially the south- and west-facing walls, before slipping inside through tiny cracks and gaps.

This explains why you may suddenly notice dozens gathering on your windows or porch in early fall.

Are Stink Bugs Harmful?

Stink bugs are more of a nuisance pest than a health threat. They don’t cause structural damage, and they won’t harm people or pets. The main concerns are:

The Odor: When disturbed or crushed, stink bugs release a foul-smelling chemical that lingers.
Overwintering in Numbers: Once inside, stink bugs can gather in the hundreds within walls or attics, making them difficult to remove.
Crop and Garden Damage: For homeowners with gardens, stink bugs can damage fruits, vegetables, and ornamental plants.

How to Prevent Stink Bugs From Entering Your Home

Prevention is the most effective form of stink bug control in North Carolina. By making your home less inviting, you can reduce the chances of an indoor infestation.

Seal Entry Points

Inspect windows, doors, and siding for cracks.
Apply fresh caulk around frames and utility openings.
Replace or repair torn window screens.
Check weatherstripping and door sweeps.

Reduce Outdoor Attractants

Limit outdoor lighting in the evenings, or switch to yellow “bug lights.”
Keep vegetation, weeds, and brush trimmed back from your foundation.
Store firewood away from your home to prevent stink bugs from hiding nearby.

Handle Indoor Sightings Gently

If stink bugs find their way indoors, avoid squashing them. Instead:

Use a vacuum with a disposable bag to remove them without releasing odor.
Release them outside when possible.
