If you're a homeowner in the United States, you're likely familiar with the pesky stink bug. These shield-shaped invaders, known scientifically as Halyomorpha halys, emit an unpleasant odor when threatened or crushed, hence their name. As fall approaches, stink bugs start seeking warmth and shelter indoors, making them a common household pest. But what keeps stink bugs away? Let's delve into some effective strategies to deter these unwanted guests.
Understanding Stink Bug Behavior
Stink bugs are attracted to light and heat, which is why they often end up in homes during the cooler months. They feed on a variety of plants, including fruits, vegetables, and ornamental plants, making them a nuisance in gardens and farms alike. To keep stink bugs away, it's crucial to understand their behavior and target their entry points.
Sealing Entry Points
Stink bugs can squeeze through incredibly small gaps to gain entry into your home. A thorough inspection of your home's exterior is the first step in preventing their invasion. Look for cracks and crevices around windows, doors, vents, and plumbing pipes. Use caulk, foam sealant, or weatherstripping to seal these entry points. Pay special attention to areas where utility pipes enter the house, as these are common stink bug entry points.
Window and Door Screens
Installing window and door screens can help keep stink bugs out while still allowing fresh air into your home. Ensure the screens fit snugly and are in good repair to prevent stink bugs from squeezing through any gaps.
Natural Repellents
Several natural substances can repel stink bugs. Incorporating these into your pest control strategy can help keep stink bugs away without the use of harsh chemicals.
Essential Oils
Essential oils like geranium, peppermint, and lemongrass are known to repel stink bugs. Mix a few drops of your chosen oil with water in a spray bottle and apply it around windows, doors, and other potential entry points. You can also soak cotton balls in the oil mixture and place them in strategic locations.

Herbs and Plants
Stink bugs dislike certain plants and herbs. Planting these around your home can help deter stink bugs. Some effective options include catnip, marigolds, and lavender. You can also place potted herbs like these near windows and doors for added protection.
Physical Barriers
Creating physical barriers can help keep stink bugs away from your home and garden. Here are a few strategies to consider:
- Row Covers: In the garden, stink bugs can be kept away from plants by using row covers. These lightweight fabrics allow sunlight, water, and air to pass through while keeping pests out.
- Sticky Traps: Placing sticky traps near potential entry points can help catch stink bugs before they enter your home. These traps are available at garden centers and hardware stores.
Professional Pest Control
If stink bug infestations persist despite your best efforts, it may be time to call in a professional pest control service. These experts have access to specialized treatments and can provide guidance tailored to your specific situation. They can also help identify and seal any additional entry points you may have missed.
Preventing Future Infestations
Once you've successfully kept stink bugs away from your home, it's important to take steps to prevent future infestations. This includes regular inspections of your home's exterior, prompt repair of any damage, and continued use of natural repellents and physical barriers. By staying vigilant, you can keep stink bugs at bay and enjoy a pest-free home.
