How to Get Rid of Stink Bugs in Wisconsin

Have you noticed shield-shaped bugs creeping into your home as the weather cools? If so, you’re not alone. Stink bugs in Wisconsin are a growing nuisance, especially in the fall.

These pests don’t bite, but they emit a foul odor when disturbed. If you don’t act quickly, they can multiply and become a real problem. 

What Are Stink Bugs, and Why Are They in Your Home? 

Stink bugs, particularly the brown marmorated stink bug (Halyomorpha halys), are invasive pests that have spread throughout Wisconsin. They enter homes seeking warmth in fall and winter. Once inside, they hide in walls, attics, and other cozy spaces. 

Quick Facts About Stink Bugs 

• Stink bugs release a pungent odor when crushed or threatened. 

• They do not harm humans but can damage plants and crops. 

• According to the USDA, stink bugs have caused millions of dollars in agricultural losses. 

• Light and warmth attract them, making your home an ideal target. 

How to Prevent a Stink Bug Infestation 

The best way to control stink bugs is to keep them from entering your home in the first place. Here’s what you can do: 

✔ Seal Entry Points—Inspect windows, doors, and vents for gaps. Use caulk or weather stripping to seal cracks.  
✔ Install Screens—Keep stink bugs out by adding mesh screens to vents and chimneys.  
✔ Reduce Outdoor Lighting—Stink bugs are attracted to lights. Keep outdoor lights off when not needed, or use yellow-tinted bulbs that attract fewer bugs.  
✔ Eliminate Food Sources—They feed on fruits, vegetables, and plants. If you have a garden, inspect it regularly.  
✔ Use Essential Oils—Peppermint oil or a mixture of dish soap and water can act as natural repellents. 

How to Get Rid of Stink Bugs Inside Your Home 

If stink bugs have already made their way indoors, take these steps to eliminate them: 

Vacuum Them Up—Use a vacuum with a bag to capture stink bugs without crushing them. Dispose of the bag immediately to prevent odor spread.  
Trap Them—Fill a dish with soapy water and place it near a light source. This arrangement will draw in and drown the stink bugs.  
Use DIY Sprays—Mix water, dish soap, and white vinegar in a spray bottle. Spritz directly on stink bugs.
