Calls come pouring in every fall from homeowners who want to get rid of stink bugs after spotting the brown, shield-shaped pests clinging to walls and windows. If you live in the St. Louis area, you know the drill: once the temperature drops, stink bugs appear out of nowhere.

According to the North Carolina Extension of the Entomology Department, brown marmorated stink bugs (BSMBs) move into structures to overwinter in September and October. Stink bugs in your home remain in diapause or dormancy, reducing activity. When they overwinter, BSMBs do not feed or lay eggs. However, a lot of stink bugs have been known to clog heat pumps or power equipment during this time.
What makes stink bugs such a headache is their persistence. We’ve seen families vacuum them up to get rid of stink bugs, only to have more turn up the next day. Businesses sometimes find them clustered in storage rooms or even office spaces. For people with allergies, the odor can even cause headaches or discomfort. The good news? You’re not alone. Stink bugs are everywhere, but with the right approach, you can keep them out for good.
Why Stink Bug Populations are Increasing
This isn’t your imagination. Studies from Missouri Extension and local universities show that stink bug numbers have surged over the last few years, thanks to milder winters and changing weather. In some neighborhoods, it feels like they invade overnight.
The Missouri Department of Conservation notes that brown marmorated stink bug numbers are expected to increase, with milder climates allowing for more generations per year – up to five generations annually in southern states compared to one or two in Missouri.

The research indicates that stink bugs dislike cold winters, and rising temperatures brought by climate change create more suitable conditions for their survival and reproduction.
University of Missouri assistant entomology professor Kevin Rice has noted large population increases in brown marmorated stink bugs, with expectations that they will spill over into agriculture and cause damage in the coming years.

When Stink Bugs Get Inside Overnight
BSMBs invade overnight. These stink bugs enter your home through the smallest cracks and crevices.
What makes these pests such a headache is their persistence and pungent odor. We’ve seen families vacuum them up, and the next day, more turn up in their basements, attics, or crawl spaces. Without professional help, it can be challenging to deter stink bugs. You’ll need more than a homemade remedy like peppermint oil, especially when they accumulate.
Businesses sometimes find them clustered in storage rooms or even office spaces. For people with allergies, the stinky, pungent smell can even cause headaches or discomfort when they get accidentally squished. The good news? You’re not alone. Brown marmorated stink bug infestations are everywhere. With the right pest control approach, you can keep stink bugs away for good.
Titan finds why brown marmorated stink bugs may be attracted to your place and will get rid of them so they won’t return.
What Are Brown Marmorated Stink Bugs & How Do They Get Inside Your Home?
Brown marmorated stink bugs are about the size of a dime. They have rigid, shield-shaped bodies and banded legs. These stinkbugs give off a strong, musty, pungent odor when squished or disturbed. These pests are invaders from Asia. They have recently spread rapidly across Missouri and the Midwest, becoming a significant pest problem.
How do they get in? Brown marmorated stink bugs are talented at slipping through tiny gaps, cracks, or holes around your home. They typically find access around windows and doors, siding, and attics. When the weather cools, they’re looking for a warm place. They sneak inside homes and businesses to overwinter indoors.
We’ve helped homeowners who thought their houses were airtight. They discovered stink bugs tucked behind curtains or light fixtures. One business manager even found dozens hiding behind a wall sign. Once one gets in, it’s only a matter of time before others follow. Stink bugs often release a scent trail that attracts even more bugs to the exact location.
What the Experts Say
Expert note: Stink bugs overwinter in sheltered spots. They often release a scent trail that attracts even more bugs, making it feel like they’re everywhere simultaneously. You may have noticed a lot more around your home recently.
According to the University of Georgia, the dormant period is critical. BMSBs enter diapause to overwinter, survive this period, and reproduce in the spring. The life cycle from egg to adult lasts 40 to 60 days, depending on the temperature.
Why Do I Suddenly Have So Many Stink Bugs in My Home?
When it gets cool outside, stink bugs gather. They look for warm places to spend the winter. That’s why you’ll see a sudden surge around doors, windows, and siding as soon as fall hits. If you’re trying to find a way to keep stink bugs away or keep the bugs out of your home, you need to call Titan Pest and Wildlife Solutions. Whether you have bed bugs, stink bugs, or any other kind of pest, you must consult the professionals for effective pest control.
When fall arrives, many customers complain, “I have stink bugs in my home.” However, you must also consider that BMSBs can damage fruits and crops outside of your home. Once they leave their overwintering shelters, they may move outside around your vegetation. In these cases, a broad-spectrum insecticide is recommended to prevent the stink bug infestation from spreading.

What Triggers a Stink Bug Infestation?
Warmth, light, and sheltered spaces draw stink bugs in. Bugs are attracted to light sources, especially outdoor lighting near entry points. Once the insect finds a good hiding spot in your home, it leaves a scent that calls more stink bugs to join the party. Stink bugs are attracted to:
- Warm places like heated homes and buildings
- Light sources, particularly outdoor lighting
- Cracks and crevices in siding, windows, and doors
- Areas where they can seal your home entry points
Are Stink Bugs Dangerous for My Family, Pets, or Business?
“Are stink bugs dangerous?” That’s usually the first question people ask. The answer is simple. Stink bugs are mostly just nuisance pests. They don’t bite, sting, or spread disease. Their primary defense is that infamous pungent odor, which can linger if bugs are crushed or squished.
Don’t Squish a Stink Bug
Some people are sensitive to the stinky smell, which might trigger headaches or mild allergic reactions. Pets sometimes try to eat stink bugs. Thankfully, they’re not poisonous, but eating one may cause your dog or cat to drool or feel queasy.
Businesses worry about stink bugs getting into customer areas. This is especially true for food service or hospitality businesses. While these pests don’t carry germs, their presence can be off-putting for guests. One daycare called us after teachers found stink bugs near a play area. Parents were worried. We reassured them that stink bugs aren’t dangerous. They’re unpleasant to have around and can become a problem if left untreated.
DIY Stink Bug Solutions: Do They Work?
It’s normal to try fixing a stink bug problem on your own. We’ve heard many DIY stories. People try soapy water, essential oils like peppermint and neem oil, white vinegar, and vacuuming. These tricks can work for a few bugs, but they rarely get rid of stink bugs completely. More are usually hiding in walls, attics, or basements.
The bug is a survivor. If you only treat the ones you see, more are probably hiding behind the walls or in the attic. Some homeowners chase stink bugs with a handheld vacuum.
While that can remove a few, it can also spread the smell through your vacuum bag and into other rooms. One client thought they’d won the battle. They found even more bugs the following week.
DIY sprays and traps rarely reach the source of the infestation. Worse, some over-the-counter products like Home Defense Max are not always safe for kids or pets. It’s easy to get stuck in a cycle. You kill a few, more appear, and the problem continues.
Does White Vinegar Kill Stink Bugs?
White vinegar can help repel stink bugs and deter them from certain areas. It doesn’t kill them on contact, but it may make them leave for a bit. It won’t solve an infestation or prevent stink bugs from returning.
What is the Best Way to Get Rid of Stink Bugs with Homemade Solutions?
A simple mix of dish soap and water in a spray bottle can kill stink bugs when sprayed directly. This soapy water works for the bugs you see , but won’t reach the ones hiding in cracks or walls. Other homeowners try diatomaceous earth around entry points. This method has limited effectiveness for serious infestations.
How to Get Rid of Stink Bugs: Step-by-Step Way to Get Rid of This Pest
If you want real results, use a mix of prevention and smart removal. Here’s the best way to get rid of stink bugs and keep stink bugs away:
- Use a Vacuum (Carefully)
Suck up visible stink bugs with your vacuum. Use a separate vacuum if you can. The pungent smell can linger in your vacuum bag. Empty it outside right away to prevent the odor from spreading indoors.
- Light Trap with Soapy Water
Fill a container with water and a few drops of dish soap. Gently knock stink bugs into the soapy water using a piece of paper or a small scoop. The soap kills them quickly without squishing them. This prevents releasing their stinky odor.
- Seal Entry Points Around Your Home
Check for cracks or gaps around windows, doors, siding, and your home’s foundation. Use caulk or weatherstripping to seal any cracks and keep more stink bugs out. Remember, stink bugs can enter your home through the smallest openings.
- Repair Screens and Door Sweeps
Fix any tears in the window or door screens. Make sure door sweeps fit tightly. Even tiny openings can let stink bugs slip inside your home this winter.
- Reduce Outdoor Lighting
Bright lights attract stink bugs because bugs are attracted to light. Try using yellow “bug” lights. Keep porch and patio lights off at night to prevent stink bugs from gathering near your home.
- Remove Yard Debris
Clear away leaves, weeds, and piles of wood or clutter near the house. Don’t store firewood directly against your home’s exterior. Stink bugs love to hide in these spots before sneaking inside. This helps keep the bug population away from your home.
- Use Professional-Grade Insecticide Treatments
Store-bought repellent sprays don’t reach hidden bugs or eggs. Our technicians use targeted, safe insecticide treatments that work inside and out. These knock down infestations fast and provide effective pest control.
- Prevent with Year-Round Pest Control Protection
The best fix is ongoing pest control. We offer Home Shield and Business Shield plans with regular inspections, preventive treatments, and year-round peace of mind to keep stink bugs and other pests away.
Pro Tip: Never squish a stink bug. Squishing just releases more of their signature pungent odor! Always trap and remove gently for best results. This way, stink bugs can’t spread their stinky smell throughout your home.
- Kill Stink Bugs Instantly
A mix of dish soap and water kills stink bugs on contact. Vacuuming works too. Be sure to empty the vacuum bag outside to avoid the pungent smell spreading indoors.

How Long Will Stink Bugs Live in My Home?
Brown marmorated stink bugs can be tough to remove once they’re inside. Stink bugs tend to look for dark, hidden spots. These include attics, behind picture frames, or inside appliances in your basement or crawl spaces. Some can live for months without food, making them hard to find and more challenging to remove from your home this winter.
We’ve found stink bugs hiding in places no one expects. We’ve seen them inside unused electrical outlets. Without professional pest control help, they can survive indoors all winter. They reappear in spring when they leave their overwintering spots.
Stink bugs can survive for months inside. Sometimes they make it through the entire winter until it’s warm enough to go outside again. During diapause, these pests remain dormant but alive in your home.
Prevention: How Do I Keep Stink Bugs Away for Good?
Prevention is the real secret if you want to get rid of stink bugs and keep them from returning year after year. Here’s what works to keep stink bugs away and prevent stink bugs from entering your home:
- Seal up cracks and gaps around windows and doors, siding, and foundations with caulk
- Repair or replace torn screens on windows and doors
- Use door sweeps and weatherstripping for a tight seal
- Keep outdoor lighting off at night or switch to yellow bulbs since bugs are attracted to light
