As the seasons change, you might notice some unwelcome, shield-shaped visitors making their way into your home. The Brown Marmorated Stink Bug, an invasive species from Asia, has become a common nuisance across Pennsylvania. While they don’t bite or cause structural damage, their tendency to congregate in large numbers—and release a foul odor when disturbed—makes them a pest you’ll want to keep out.

Fortunately, there are effective ways to prevent stink bugs from turning your home into their winter getaway. This guide will walk you through what attracts these pests and provide actionable steps to keep your property stink bug-free. If you find yourself with an infestation, the experts at Patriot Pest Solutions are always here to help.

Understanding Stink Bug Behavior

To effectively control stink bugs, it’s important to understand why they enter your home in the first place. Stink bugs are attracted to warmth and light. During the warmer months, they live outdoors, feeding on fruits, vegetables, and ornamental plants. As autumn approaches and temperatures drop, they seek shelter to survive the winter, a process known as overwintering.

Your home offers the perfect refuge—it’s warm, safe from predators, and provides plenty of cracks and crevices to hide in. They are particularly drawn to the sunny sides of buildings and will exploit any small opening to get inside. Once one stink bug finds a suitable spot, it releases a pheromone that attracts others, which is why a single bug can quickly lead to a full-blown infestation.

How to Prevent Stink Bugs from Entering Your Home

Prevention is the most effective strategy for dealing with stink bugs. By sealing off potential entry points before they have a chance to get in, you can save yourself a lot of hassle. Here are six key steps to protect your home.

1. Seal Cracks and Gaps

Thoroughly inspect the exterior of your home for any openings. Stink bugs can flatten their bodies to fit through surprisingly small spaces. Pay close attention to:

• Siding and trim: Look for gaps around window frames, doorframes, and along the foundation.
• Utility pipes: Check where pipes, wires, and cables enter the house.
• Chimneys and vents: Ensure these are properly sealed or screened.

Use a high-quality silicone or silicone-latex caulk to fill any cracks you find. For larger gaps, you might need to use steel wool or expandable foam before sealing.

2. Repair Damaged Screens

Torn or damaged window and door screens are an open invitation for stink bugs. Carefully examine every screen in your home, including those on attic vents and crawl space openings. Repair any holes or tears, no matter how small. If a screen is beyond repair, replace it. This simple fix not only keeps stink bugs out but also helps deter other pests like flies and mosquitoes.

3. Install Door Sweeps and Weather Stripping

Gaps under doors are a common entry point for pests. Install door sweeps on all exterior doors to close this gap. You should also check the weather stripping around your doors and windows. If it’s worn, cracked, or missing, replace it to create a tight seal that bugs can’t penetrate.

4. Reduce Outdoor Lighting

Stink bugs are attracted to light, so managing your outdoor lighting can make a significant difference. Where possible, turn off porch lights, landscape lighting, and other exterior lights at night. If you need outdoor lighting for security, consider using motion-activated lights or switching to yellow “bug light” bulbs, which are less attractive to insects. Closing your blinds and curtains at night can also prevent indoor lights from drawing them toward your windows.

5. Remove Stink Bugs You Find Indoors

If you find a few stink bugs inside, it’s important to remove them carefully to avoid triggering their signature odor. The best method is to gently scoop them up with a piece of paper or guide them into a jar and release them outside, far from your house.

Alternatively, you can use a vacuum cleaner with a disposable bag to suck them up. Immediately dispose of the bag in an outdoor trash can to prevent the smell from lingering in your vacuum. Avoid crushing them, as this will release the unpleasant smell they are named for.

6. Keep Your Yard Tidy

While not a direct entry prevention method, maintaining your yard can make your property less inviting to stink bugs. These pests feed on a wide variety of plants, including weeds. Regularly mow your lawn, remove weeds, and clear away any overgrown vegetation near your foundation. This reduces their food sources and hiding spots, making your home a less appealing target.
