Our Comprehensive Buying Guide


Stink bugs are pests that can invade your yard or your home and can even ruin some of your garden plants, and this is why it is important that you get rid of them as soon as possible. In order to understand how to get rid of stink bugs, you should first know a thing or two about them. 

For example, one of the most annoying, the brown marmorated stink bug, has its origin in Asia and it is believed to have been accidentally introduced to the United States only in the 1990s.

It is easier to control pests that originate in the United States because they usually have a predator, but when it comes to certain stink bugs, the only species that are their enemy are humans and it is essential to control their life cycles because, if not, they can multiply out of control.

What are the types of stink bug killers?

If you are wondering how to kill stink bugs, you should know that there are three types of stink bug killers. You can choose between an organic stink bug killer, a stink bug killer chemical, or an electrical one that you usually have to connect to an electrical outlet if it doesn’t come with batteries.

Also, they can even come in the form of a concentrate that you usually have to dilute in order to use safely, or in the form of a stink bug killer spray that is ready to use. Even if you get a concentrate, you will eventually also use it as a stink bug spray.



If you want to use a natural product that does not use any chemicals, you should know that the most popular active ingredient is neem oil. Neem oil works on different types of insects and it is known among the best natural insect repellents. Cheap stink bug killers, if they are using natural ingredients, might not contain the highest quality essential oils.

Neem oil is also a stink bug repellent and will have the effect of keeping them away, but not all of them will. The most used ingredients in the products that use chemicals, like the Harris stink bug killer or the Terro stink bug killer are bifenthrin and deltamethrin. Others that are also used are acetamiprid, fenpropathrin, and cyfluthrin.

These ingredients kill the bugs on contact and some of them also have a repellent effect that can last even for a year, according to the concentration used.

Other features

An affordable stink bug killer also has to be easy to apply. Ready-to-use stink bug spray killer products are usually a great choice, but if you have an infestation and you need to use larger amounts of product then you should buy a concentrate. 

There are a lot of affordable stink bug killers that come in the form of an electrical device, unlike what you have seen in most Terro stink bug killer reviews, which are sprays, not electrical devices. 

These products usually use pheromones to attract the stink bugs inside where they get trapped and are not able to get out. Some of them use light to attract them or both.

If you want to go for an electrical cheap stink bug killer, you should know that the only thing you should look for is for it to be able to trap insects regardless of what it uses to attract them inside. They will work just fine as well, but the ones that come with higher quality are, obviously, the ones to look for.



Frequently Asked Questions:


Q: What attracts stink bugs in your house?

Stink bugs are similar to fruit flies in one aspect, the one that refers to what they are drawn to. Yes, we are talking about ripe fruit. This is one of the most popular things that attract them into your home. If you have fruit trees around your home, you should clean the fruit that falls on the ground as soon as you see it because, if not, you will be surprised with a visit.

During the night, stink bugs are attracted to light, so a good practice is to have your blinds down in order not to attract them. This is why electrical traps have a UV light that attracts these types of bugs to trap them.

Also, if one bug finds these attractions inside your home, it releases that bad smell that tells its friends that there is a feast, so they will be attracted by this smell also. 

Q: Are stink bugs harmful to humans?

Because stink bugs are so common around the United States, many people ask the question ‘can a stink bug hurt you?’. The thing is that there are a multitude of species of stink bugs and most of them cannot bite or sting. This is why you wouldn’t worry about your safety if you see one around.

However, there are a few that can bite if you touch them but a stink bug bite will not harm you because the bite will not release any poison. They are called stink bugs because the only thing that they can do in order to stay out of danger is to release the bad smell.

If you have an infestation, the smell can be a little bit of an inconvenience and you should definitely get rid of them. However, you don’t need to be afraid of them because they will not be able to hurt you.


Q: How do you keep stink bugs away?

A good practice is to throw garbage away as often as possible and to not let any overripe fruit lying around your home. The problem with stink bugs is that they are fond of warm weather and during the summer you might not have a problem indoors, but once the winter comes, they will get inside your home. 

It usually happens that one bug gets inside and it releases a substance that will tell the others that it found a cozy place. So it is best either to prevent them from entering your home by using a repellent or to buy a trap that will kill the first ones so that they will not call their friends.

You should also cover all the cracks that might be acting as entrances for this type of bug and make it a habit of closing the door or have an insect net installed in order to avoid a stink bug infestation.

I’ll give this Deltamethrin a try. So far not one thing has help in over four years. I killed over 500 of them on my deck today, it’s never ending.
