The Stink Bug Invasion: Why They’re in Your Home and How to Stop Them

7014692967 • June 19, 2025

Every fall, Ohio homeowners notice the same thing: brown, shield-shaped bugs crawling on windows, walls, and ceilings — especially when sunlight hits them. These uninvited guests are stink bugs, and they're not just exploring — they're house hunting.

Don't worry if you're seeing more of them lately. As temperatures drop, stink bugs naturally seek warm winter shelters, and your home is their ideal destination.

What Are Stink Bugs and Why Are They a Problem?

Stink bugs, officially called brown marmorated stink bugs, won't harm you but can be a serious nuisance. While they neither bite nor sting, they release an unpleasant odor when threatened or crushed. This smell can linger, and a large infestation can make your home unbearable.

More concerning is how difficult they are to remove once they're inside. These pests slip into tiny cracks, hide behind baseboards, and continue appearing throughout winter.

Why They Show Up in Fall

Being cold-blooded, stink bugs can't survive freezing temperatures. When autumn arrives, they search for shelter. Their attraction to warmth and light explains why you'll spot them on sun-facing walls, around window frames, and near light fixtures.

They infiltrate homes through vents, gaps in siding, damaged screens, and door gaps. Once inside, they hibernate in attics, crawlspaces, or wall voids until spring, when they emerge in masses.

DIY Tips to Keep Stink Bugs Out

Prevention is your best defense against stink bugs. Here's what you can do now:

Seal cracks and gaps around windows, doors, and siding
Install door sweeps and repair or replace damaged screens
Use weather stripping on garage doors and basement windows
Turn off unnecessary exterior lights at night — they attract stink bugs
Vacuum them up instead of squishing them if they get inside (to avoid the smell)

While these measures help, DIY methods often fall short once stink bugs have invaded your walls.

One-Time Pest Control vs. Year-Round Protection: What Ohio Homeowners Need to Know

By 7014692967 • August 11, 2025

When pests show up, it’s tempting to call for a one-time treatment and be done with it. After all, if the bugs are gone, the problem’s solved — right? Not quite. The reality is pests don’t just pop up randomly. Their activity follows seasonal patterns, environmental conditions, and even the layout of your home. A single spray might offer relief, but pests will be back — unless you stop them at the source. Here’s why year-round pest control is a smarter investment for Ohio homeowners.
