10 Simple Steps to Keep Stink Bugs Out of Your House


Stink bugs stink, plain and simple. Getting rid of stink bugs is complicated, and your best defense against these pests is keeping them out of your home in the first place.

To keep stink bugs out of your house, you need to execute strategies that protect your home from outside intrusion. The best methods include caulking gaps around exterior doors and windows, replacing torn screens, and using an insect repellent around the exterior of your home.

The rest of this article will discuss a detailed list of ways to keep stink bugs out of your home (hopefully for good), things to consider when purchasing stink bug repellent, and our list of the eight best repellents for stink bugs.

10 Steps to Keep Stink Bugs Out of Your House

The best way of handling stink bugs is to prevent them from entering your house in the first place. There are a variety of other methods of keeping stink bugs out of your home, including the ten steps we detailed below.

To comprise this list, we researched a variety of governmental sources to include the Environmental Protection Agency, the United States Department of Agriculture, and the National Pesticide Information Center (a cooperative agreement between Oregon State University and the Environmental Protection Agency).

Likewise, we researched several academic sources to include the Michigan State University Extension, Rutgers University, and the West Virginia University Extension.

Before we go any further, we’d be remiss if we didn’t let you know about our nationwide network of pest control providers. One of the best ways to prevent stink bugs is to use an insecticide around the base of your home.

If you’re experienced in handling this, the more power to you. However, you may very well need an exterminator to handle the issue for you. If you’re interested, contact our partners today and we’ll connect you with a local exterminator in your area in seconds for free. That’s it!

Let’s get to it!

Sealing the Outside of Your House Keeps Stink Bugs Out

Entry can be significantly reduced or eliminated in older wood-frame houses by caulking and sealing crevices and cracks on the home’s exterior.

However, it is difficult, if not impossible, to keep stink bugs out of homes with vinyl siding because the siding and soffits are loosely nailed or hung to allow the panels to contract and expand with changes in outside temperature.

If sealing the outside of the home doesn’t prevent stink bugs from gaining entry into the house, try caulking around electrical outlets, switch boxes, heating ducts, and ceiling fixtures. Likewise, look for other openings in interior walls such as vents that might be the source of the infestation.

Using Light Traps Helps Keep Stink Bugs Out of Your House

The University of Florida Extension reported that light sources attract the most common varieties of stink bugs. For that reason, installing light traps in attics and basements is a great way to capture stink bugs at night, solving your infestation problem before it can get started.

Researchers from Polytechnic Institute and State University along with participating citizen scientists concluded that aluminum water pan traps are the most effective traps tested for catching stink bugs.

Making your own aluminum water pan trap is as easy as one-two-three. All you need is a deep roasting pan, a lamp to attract the stink bugs (stink bugs use black light as a visual queue, so try this Gohyo 9 LED Blacklight), and some soapy water. It is best to use an aluminum pan so you can toss it in the garbage when you are done using it. After all, who wants to use a bug pan for preparing dinner!

Moving along, fill the pan with water and dish soap. Next, place the container in your attic, basement, or wherever else you think stink bugs might be entering the home. Then, point a lamp downwards towards the pan and get ready for some action.

When using light traps, be sure to put enough water in the pan as stink bugs can be rather large. Best of all, costs associated with making a light trap are nominal, and the study found that light pans are typically more effective than store-bought insect traps.

And, as a bonus, this trap will likely trap other insects at the same time it is taking care of your stink bug problem for you!

Rubbing Dryer Sheets on Your Window Screens Repels Stink Bugs

Yes, you heard that right. Good Housekeeping Magazine claims that rubbing fragrant dryer sheets can significantly reduce the level of infestation by stink bugs. Be sure to wipe the sheets across the entire surface of the screens to make sure the scent lingers.

Of course, there are many variables to using this method, but it could be a good stop gap for you while you work on a more permanent solution.

Use a Peppermint Spray to Repel Stink Bugs

Made with all-natural and organic ingredients, mdxconcepts Organic Magma Home Pest Control Spray is a very highly regarded peppermint based spray to defend against stink bugs.

Its main active ingredients include peppermint, spearmint, and rosemary essential oils which, should work pretty well to deter stink bugs as they dislike the scent and stay away from it.

Additionally, all MDX products are USDA certified.

Magma Home Pest Spray claims to control and repels a wide variety of pests to include stink bugs, ants, earwigs, fleas, mites, scorpions, silverfish, spiders, and more.

With its combination base of essential oils, this is another product that you should enjoy for its scent, let alone the repelling of stink bugs!

Minimize Lighting Outside Your House

Lights attract stink bugs and other pests. Turning off outside lighting when you don’t need it or replacing the bulbs is a great way to make your house less attractive to stink bugs.

Better yet, purchase some solar-powered motion sensor lights like this set of four lights made by Baxia Technology and save yourself a nickel or three on your electric bill.

Unless your using a yellow / red light, this will also help to decrease the traffic of mosquitoes and gnats outside your home as well.

Spray Around the Perimeter of Your House With Insecticide or Repellent

Spraying the exterior wall of your home with a suitable insecticide or repellent is a great way to prevent stink bugs from gaining entry into your home. The repellent should be applied around September when bugs typically begin congregating on your walls, looking for a warm place to live.

If you have others in your home, make sure you read the labels on products before using them. Better yet, take a look at our list of repellents towards the bottom of this article and start your research based on that.

Again, if you aren’t experienced in doing this yourself, your best bet may be to hire an exterminator to spray insecticide around the base of your home. You can contact our nationwide network of pest control providers to find a local exterminator near you in seconds!

Install Door Sweeps or Weatherstrip Entry Doors

Weatherstrip and door frames showing light around their perimeter. Likewise, install door sweeps if you can feel a draft or if any light shines beneath any doors.

Door sweeps are super helpful as they can help to keep dust and debris out of your home as well, leading to less sweeping and vacuuming on your end too!

Repair or Replace Any Torn or Damaged Outside Screens

It sounds obvious, but not everyone takes the time to fix or replace torn or worn out window screens. Likewise, repair or replace any screen covering outside vents if they appear worn or damaged.

This one is kind of a big one. One summer, I was getting some pretty rough bug bites INSIDE my apartment. Come to find out, I had a massive rip in my window screen that was always left open.

While stink bugs don’t bite (I was getting bit), they’re still able to get through wide open windows pretty easy.

Cap or Screen Chimneys or Any Heating Vents on the Roof

Stink bugs have no problem getting up to your rooftop. For that reason, make sure you install caps or screens on any chimneys or heating vents you have protruding from your house’s roof.

This is also a best practice method for any potential bats that may want to nest in you chimney during the cooler months as well. Best to make sure the fireplace is capped if you don’t plan on using it.

Remove Any Debris From Around Your House’s Foundation

Stink bugs love debris and vegetation pushed up against your house’s foundation. Break out a rake, and edger, or a lawnmower and clear out any overgrowth or rubbish accumulated over the years. Likewise, you might also consider contacting an exterminator to spray any plants growing next to your house.

Next on the list, we’re going to talk about actual stink bug repellents/insecticides.

How to Select the Best Stink Bug Repellent

Choosing the best stink bug repellent depends on a variety of factors. 

First and foremost, that means looking at the safety of the product. You’ll want to make sure you read the product label very carefully and the directions for use in it’s entirety and if it’s proper to have around your home.

One simple and often very overlooked way to make sure that excess product isn’t lying around is to purchase only the amount of repellent needed for the current season as that eliminates the need for storage.

Next, you should consider the amount of coverage in the container, followed by how long the product lasts. Protecting your entire house from outside intrusion by stink bugs typically requires a significant amount of product.

Last, you should consider the product’s ease of use and whether another purchase, like a sprayer bottle or pressure sprayer, is recommended or required.

For further information, you can click here to go to a comprehensive web page published in cooperation with the U.S. Environmental Protection Agency and Oregon State University.

If you plan on using one of the recommended insecticide solutions below, you’ll want to MAKE SURE you know what you’re doing with these, as some are heavy duty insecticides.

If you don’t have experience applying insecticide, we recommend contacting our nationwide network of pest control providers where we’ll connect you with an exterminator in your local area in seconds.

How Big of an Area Does the Container Cover?

Concentrated liquids typically offer the best coverage for insect repellents, particularly if your goal is creating a barrier around your entire home. Additionally, you should consider whether or not the coverage area slopes downward towards any sensitive areas or near any fruit or vegetables you are growing outside.

You don’t want either location contaminated by insect repellents of any kind.

How Long Does the Repellent Last?

The persistence level of insect repellents varies greatly depending on brand and type. Some products offer short-term protection, while others last longer.

For example, powdered repellents can last for as long as a year. On the other hand, liquid pesticides typically last for only a few weeks or months. It is up to you to decide which product better suits your particular situation.

Not all pesticides are the same. Some offer long-term protection, while others offer a shorter period of control. Ultimately, the decision is up to you which road to take when purchasing repellent to keep stink bugs out of your home.

Is the Repellent User-Friendly?

Powdered repellents are lightweight and typically don’t require the purchase of any special equipment. Inversely, liquid repellents are more cumbersome, and usually require additional equipment like high-pressure sprayers. Again, if you don’t have experience in this regard, it may be best to leave it to the experts.

The decision is ultimately up to you. However, it is best to err on the side of caution if you have any doubts regarding the safety of a particular product.

8 Repellents That Will Keep Stink Bugs Out of Your House

With more than 300 varieties, stink bugs are an invasive pest that thrives throughout the United States. Although they pose the highest risk to gardens, they are also a nuisance to people because they feed on indoor plants.

The effective use of insect repellents is a sure-fire way of combating this problem. Below is our list of nine repellents to use to keep stink bugs out of your home.

We selected these nine insect repellents by researching the best-selling brands. Additionally, we considered the reputation of each product, its ease of use, price, and overall reviews.

What We Learned Today

We covered a lot of information today regarding the best way to keep stink bugs out of your house. The choice is up to you as to which method you use.

Essentially, stink bugs are a bothersome pest to deal with because if you deal with them in your habitual manner (to squish them) you’ll immediately regret it.

The best way to keep stink bugs out of your home is to use PREVENTATIVE methods. Make sure your house foundation is free of cracks, don’t leave wide open rips in screen doors or windows, keep the doors closed, use a light trap or even spray an insecticide.

You may find it most useful to hire an exterminator once a year to spray the foundation of your home. This is a fairly common and effective way to keeping bugs out of your home as professional treatments generally last longer than DIY ones.

However, the tradeoff is that the cost is much higher, but you do get added piece of mind. The choice is yours!
