Diatomaceous Earth (DE)

Diatomaceous earth is a food grade powder made from a natural sedimentary rock which contains iron oxide, silica, and alumina. DE is extremely fatal to insects but safe on animals and humans.

As you sprinkle DE, focus on entryways such windowsills, on doors and door frames alongside other areas where stink bugs seem to hang out frequently. Additionally, if you spot a live sting bug, you should directly dust the powder on it.

If used regularly, you will start seeing a reduction in stink bugs and even other types of insects in your home.

Sprinkle Catnip

Catnip is also another effective stink bug repellent. It repels and scares away stink bugs instead of poisoning them. To use catnip as a repellent, you can sprinkle catnip powder around your home and in your garden. Make sure that you focus on areas where stink bugs tend to hide out or congregate.

Spray this solution directly on live stink bugs especially in areas where they congregate in big numbers. Spray this mixture every day. After a week or two, you should start seeing a change in numbers of stink bugs in your home.

If you rub your eyes with hot pepper or accidentally spray it in your face, it can cause serious irritation and burn your eyes and skin. Make sure that you wash your hands thoroughly after mixing the hot pepper spray before doing anything else.

Use Soapy Water

Soap is an effective home remedy that kills the stinky insects by breaking down their exterior leaving them dehydrated. A mild dish wash is ideal for this method; it’s natural and safe. You can choose to use antibacterial soap, but it has a lot of chemicals as compared to non-antibacterial soap.

To make the soap water mixture, you will need to mix about 4 cups of dish soap and one liter of hot water. Spray the soap water solution directly to live stink bugs particularly in areas where stink bugs seem to hide out in large numbers. The good thing with the soapy water remedy is that it requires simple ingredients which are readily available in your kitchen.

Physical Removal

You can use physical methods alongside the home natural method and repellents to get rid of stink bugs. When stink bugs get inside your home, they do not build nests, neither do they breed and reproduce. They also won’t feed on anything inside your home. The only thing they will be looking for is a warm place to overwinter. Thus, if you use physical removal methods, you will be able to get rid of these stinky tiny insects for good.

Here are some of the effective physical methods that can be used to get rid of stink bugs.

Use an industrial vacuum cleaner that has a bag to suck up these foul-smelling insects. After vacuuming, remove the bag and dispose of immediately.

The problem with stink bugs is that that they stink once they are threatened or killed. So, after you vacuum them, your vacuum cleaner will be left with the bad smell for weeks or even months. Thus, it’s prudent to make sure that you vacuum these stinking little bugs using a vacuum cleaner with a bag. After vacuuming, empty the dead stink bugs in a garbage bag and make sure that you seal it tightly. This way, you won’t be left with a stinking vacuum and your home will not be affected by the foul smell either.

Use A Soapy Trap

Fill a bucket with four liters of water and mix a teaspoon of liquid soap or dish detergent. Mix the soapy solution until it bubbles. Place the bucket at the spot where stink bugs seem to gather frequently. Turn on a lamp and set it close to the bucket with soapy water. The idea is to illuminate the bucket of water and draw stink bugs to it.

Stink bugs, like any other insect, are attracted to light. They will fly towards the light and also get drawn to the soapy solution. They will them get into the soap mixture, and since they can’t move in the soapy solution, they will eventually drown. The soap trap is probably one of the methods that are stink free and easiest to use. The soap method can also be used to eliminate other types of insects such as fleas and houseflies.

Electrocute the Insects

When you choose stink bug spray, you should be prepared to deal with the stinking mess left behind after the bugs die. Removing dead stink bugs after spraying stink bug spray can be a tedious task, not to mention a smelly one at that.

Other common entry points include ceiling lights, baseboards, cracks on walls and foundation. Sealing the entry points will reduce the chances of stink bugs getting inside your house.

In addition, you should cover air vents, chimneys, dryer vents and any other open areas that serve as a connection between the outside of your house and the inside. Inspect your home and identify these open areas and place protective screens to cover them. If you come across holes that are one-inch-wide or more, you should patch them up using epoxy or instant adhesive.

Control Weeds Outdoor

Unless you get rid of the weeds or reduce its amount, it will be difficult to keep the smelly insects away from your home.
