How to Keep Stink Bugs Away
Stink bugs are notorious for their smelly reputation and are aptly named because of the odor they release when they sense a threat or when crushed. The bugs feed on crops, fruits, and plants; therefore, making them a significant threat to farmers. They can also damage and render some crops and fruits unfit for sale.
While stink bugs often spend winter holed up outdoors, they will also seek shelter in warm structures such as your home to escape the chilly winter months. The bugs, just like flies, don’t bite, munch clothing, or raid the pantry; however, they have one major problem, they stink!
Stink bugs release a foul smell when threatened or disturbed. While in the wild, this odor helps keep predators away; however, if they find their way to your home, the stink will linger past the time the bug might be dead because it clings to whatever the insect touches.
Here is how to keep stink bugs away naturally:
So what Attracts Stink Bugs to Your House?
Stink bugs may be attracted to your house due to various reasons. Here are some of them:
They Are Seeking Shelter
As the temperatures drop, you’ll probably notice more stink bugs in your house. They often come inside to seek shelter for diapause, which is a period in their life cycle when they’re inactive. They are not seeking warmth as most people think. If it’s warm outside, then the bugs are not diapausing.
A stink bug diapauses because, in nature, there isn’t enough food for it to eat during that time. Therefore, this period allows the bug’s metabolism to slow down to become dormant.
Your House Is Made of Natural Materials
When stink bugs go into diapause in nature, they often do it under the bark of a dead tree or hang under a big, rocky crevice. Therefore, if you have a dark home with natural siding, stink bugs might think it’s their usual hangout spot, making them stick there.
A Scent Trail Might Be Tipping Them Off
A stink bug releases a pheromone when it finds a good spot to shelter. Unfortunately, this chemical attracts other stink bugs to that location, and they invade your home.
Loose Entry Points Give Them Easy Access
Stink bugs can get into your home if it has a lot of entry points. They often sneak inside through crevices, cracks, holes, and gaps in foundations and roofs. They can also access your home through door frames and windows.
Your Home Has Lots of Lights
Stink bugs are attracted to bright lights. Therefore, if you’re dealing with a stink bug problem, it might be a great idea to turn off the exterior lights at night and pull your blinds before you head to bed.
You Live Near a Rural, Green Space
Stink bugs are herbivores; therefore, you’re most likely to find them in orchards, shrubs, agricultural fields, and extensive gardens. Therefore, if you live near these spaces, the bugs will move from their usual locations to your warmer house.
How Do You Get Rid of Stink Bugs?
If you already have stink bugs in your home, you can take a few steps to get rid of them. The measures are a combination of both preventative and removal efforts.
You might have to seal the entryways if you want to get rid of stink bugs. Start by looking for cracks around windows, vents, utility boxes, and door frames. When you find them, seal them up with foam sealant, caulk, sweeps, mesh screens, weather stripping tape, or whatever suitable material for that particular area.
It will also help to ensure that siding and pipes are also secure. Additionally, it’s advisable to close the flue if you’re not using it if you have a fireplace. Doing so might help prevent stink bugs from entering your home using that route.
If you spot stink bugs around your home, you can use your vacuum to suck them up. This method is the easiest and cleanest way of getting rid of the bugs, and you can always empty the vacuum afterward. However, it would help if you were prepared because your vacuum may smell like stink bugs for some time.
Stink Bug Traps
A homemade stink bug trap could effectively get rid of stink bugs. However, the effectiveness could depend on the severity and scale of your stink bug infestation. Here is how you can make the traps:
DIY Soap Trap
You can make a DIY soap trap using this procedure:
- Use a desk lamp with black, white, or blue light to bring the bugs to a specific location where you’re setting the trap. The bugs are naturally attracted to these types of light and other particular pheromones.
- Put a pan of soapy water underneath the desk lamp. The bugs should begin to come to the pan after about 12 hours. The soapy water will kill the bugs.
DIY Towel Trap
Follow this procedure to make a DIY towel trap for stink bugs:
- First, soak a towel in water and ring it out so it’s damp.
- Then, hang the towel in an open area, ideally away from your home.
- The stink bugs should congregate on the towel to drink the water, and the next day you’ll have a nice collection of them.
- Kill the stink bugs by dunking the entire towel in a bucket of soapy water.
- Be sure to wash the towel thoroughly before using it for anything else.
It’s best to place traps where stink bugs are most likely to congregate. Remember that these insects tend to form nests outside during the summer months and inside during the winter. While the traps are pesticide-free, they are only effective for more minor scale problems.
If you’re dealing with stink bugs on a larger scale, you could use stink bug traps for different environments that use electricity, smells, and sticky surfaces.
You can also invert the top of a plastic water bottle, put soapy water inside it, scoop up the bugs, and let them fall in and drown. Once they die, you can throw them in a sealed bag in the trash, return them into the environment, or add them to your compost pile.
Wash Your Plants
Spray your tomato plants or apple trees with water directly when you spot a stink bug on them. The water will physically force the bugs from the plants. You can also mix some mild dish soap with the water, and the solution will help break down the stink bugs’ exoskeletons and dehydrate them.
If you’re looking for a more long-term solution, you can mix water with vegetable oil, olive oil, or lavender oil. Use a garden sprayer or a regular spray bottle to apply this treatment, which will serve as a deterrent.
Fly Tape at Entryways
While using fly tape to get rid of stink bugs isn’t the prettiest of methods, strips of fly tape spread on windowsills and other entryways will help catch the critters.
You can cover a dry sweep mop head with a sticky lint remover sheet and use it as a long-handled stink bug catcher. This method is also perfect for grabbing any-high climbing bugs.

What Do Stink Bugs Eat?
Most stink bugs feed on plants. The first generation during spring often feeds on grasses or weeds. As the bugs develop into adults, they migrate into orchards, fields, and residential landscapes.
While in these environments, stink bugs will feed on apples, berries, peaches, pecans, and beans. Stink bugs also feed on field crops such as cotton and sorghum. When they’re around homes, they feed on ornamental plants.
When the bugs feed on fruits like apples or peaches, they use their mouth to pierce the fruit’s skin. During this feeding process, the bug injects a small amount of saliva into the fruit, which is very toxic to the cells of the fruit. Therefore, when the damaged fruit grows, it develops a scar that causes the fruit to resemble the face of a cat; hence, some people call stink bugs “cat-facing insects.”
The bugs also feed on the leaves and stems of plants. In addition to making fruit unfit for sale, stink bug feeding secondarily allows other insects to enter the fruit. They can also spread serious plant diseases in gardens, orchards, and farms.
It’s best to understand that a few stink bugs don’t feed on plants. Instead, they are predators of insects that attack plants. They mainly feed on root weevils, velvet bean caterpillars, southern green stink bugs, and Colorado potato beetles. Due to these feeding patterns, most consider the predatory stink bugs beneficial.
Although they don’t bite or munch clothing, stink bugs can be a nuisance. The tips above should help you repel or get rid of them. You should consider calling in professional pest controllers if you’re facing a stink bug invasion or all your efforts to get rid of them have failed.
