As the weather warms up, so does the activity of stink bugs. These shield-shaped nuisances can invade your home, causing a literal stink. If you’ve had enough of these unwelcome guests, here are ten effective ways to keep them at bay.
1. Seal Entry Points
Stink bugs are experts at finding their way inside through tiny cracks and gaps. To prevent their entry, inspect your home thoroughly and seal any potential entry points. Use caulk to seal cracks around windows, doors, siding, and utility pipes. Repair or replace damaged screens on doors and windows.
By eliminating these access points, you make it much harder for stink bugs to enter your home. A study by the University of Maryland suggests that sealing entry points is one of the most effective long-term solutions for keeping stink bugs out. (ref)
2. Use Essential Oils
Essential oils like mint, neem, and eucalyptus can be powerful deterrents for stink bugs. Mix a few drops of these oils with water and spray the mixture around entry points and areas where you’ve spotted stink bugs. The strong scent of these oils is unpleasant to stink bugs, discouraging them from entering your space.

Essential oils are a natural and non-toxic way to repel stink bugs. Mint oil is particularly effective due to its high menthol content, which irritates these pests.
3. Deploy Stink Bug Traps
Store-bought stink bug traps or homemade versions can help reduce the population of these pests in your home. These traps use light and pheromones to attract stink bugs, trapping them inside a container. Place these traps near windows and doors where stink bugs are most active.
Commercial traps are designed to be safe for indoor use and can significantly reduce the number of stink bugs. Studies have shown that light-based traps can catch a substantial number of these pests, making them a practical addition to your stink bug repellent strategy. (ref)
4. Use Garlic Spray
Garlic spray is a natural repellent that can help keep stink bugs away. To make this spray, crush a few garlic cloves and mix them with water. Let the mixture sit for a few hours, then strain it and pour the liquid into a spray bottle. Apply this spray around entry points and areas where stink bugs congregate.
The strong odor of garlic is offensive to stink bugs, making it an effective deterrent. Garlic contains compounds that are particularly repellent to stink bugs and other pests.
5. Grow Stink Bug-Repelling Plants
Certain plants are known to repel stink bugs naturally. Planting chrysanthemums, marigolds, and lavender around your home can help keep these pests at bay. These plants emit odors that stink bugs find unpleasant, deterring them from getting too close.
In addition to repelling stink bugs, these plants can also enhance your garden’s aesthetic appeal. Incorporating pest-repellent plants into your landscaping is a sustainable and environmentally friendly approach to pest control.
6. Keep Your Home Clean
Stink bugs are attracted to food residue and crumbs, so maintaining a clean home is crucial. Vacuum your floors regularly, wipe down countertops, and keep food sealed in airtight containers. Dispose of garbage promptly and keep trash cans covered.
By reducing the availability of food sources, you make your home less attractive to stink bugs. Cleanliness is a fundamental aspect of integrated pest management, helping to minimize pest infestations.
7. Use Diatomaceous Earth
Diatomaceous earth is a natural powder made from fossilized diatoms. It’s harmless to humans and pets but deadly to insects. Sprinkle this powder around entry points and areas where you’ve seen stink bugs. When stink bugs come into contact with diatomaceous earth, it damages their exoskeletons, leading to dehydration and death.
This method is effective and eco-friendly. Diatomaceous earth can significantly reduce insect populations, making it a valuable tool in your pest control arsenal.
8. Install Mesh Screens
Installing fine mesh screens on windows and doors can prevent stink bugs from entering your home. Ensure the screens are tight-fitting and free of holes. Mesh screens act as a physical barrier, keeping stink bugs and other pests outside.
Mesh screens are a simple yet effective solution. High-quality screens can block even the smallest insects, providing an extra layer of protection for your home.
9. Use Soapy Water
A simple mixture of water and dish soap can be used to kill stink bugs on contact. Fill a spray bottle with soapy water and spray it directly on stink bugs when you see them. The soap breaks down their protective exoskeleton, causing them to dehydrate and die.
This method is quick and easy. Soapy water is a safe and effective way to manage small stink bug infestations without using harsh chemicals.
10. Maintain Outdoor Lighting
Stink bugs are attracted to light, especially during their active seasons. Reducing outdoor lighting or using yellow bulbs can help minimize their attraction to your home. Yellow bulbs are less attractive to insects, helping to keep stink bugs away from entry points.
By managing your outdoor lighting, you can reduce the number of stink bugs drawn to your home. Yellow light bulbs can significantly decrease insect activity, making them a practical choice for outdoor lighting.
Repelling stink bugs doesn’t have to be a daunting task. There are plenty of practical and eco-friendly strategies you can use to enjoy a stink-bug-free home. A proactive approach is key to keeping these unwelcome guests away for good.
