What is Listerine?
Listerine is a popular mouthwash that has been around for over 100 years. It was originally developed as a surgical antiseptic but later became known as a mouthwash due to its strong antiseptic properties. Listerine contains a blend of essential oils, such as eucalyptol, menthol, thymol, and methyl salicylate, which give it its distinctive flavor and aroma.
In addition to its use as a mouthwash, Listerine has been touted as a possible remedy for various ailments, including dandruff, and acne, and even as a mosquito repellent. It is also said to be effective in killing roaches, but there is little scientific evidence to support this claim.
While Listerine is generally safe for human use when used as directed, it is important to note that it can be harmful if ingested in large quantities. Therefore, it is essential to follow the recommended guidelines when using Listerine for any purpose.
Does Listerine Kill Roaches?
While some people believe that Listerine can be an effective roach killer, there is little scientific evidence to support this claim. Listerine’s active ingredients, such as eucalyptol, menthol, thymol, and methyl salicylate, are known for their antiseptic properties, but their effects on roaches are still largely unknown.
Some experts suggest that Listerine may work as a deterrent for roaches due to its strong scent and taste, which may repel them from the treated area. However, there is no conclusive evidence that Listerine can actually kill roaches.
In fact, some studies have shown that roaches are able to survive exposure to Listerine, even at high concentrations. This suggests that Listerine may not be an effective long-term solution for roach control, especially in cases of severe infestations.
Despite the lack of scientific evidence supporting Listerine as a roach killer, some homeowners swear by its effectiveness.
Some claim that spraying Listerine directly on roaches or in areas where they are known to congregate can kill them or deter them from returning. However, the efficacy of these methods is largely anecdotal and not backed by scientific research.

Addressing the conflicting opinions about Listerine’s efficacy, some experts suggest that the effectiveness of Listerine as a roach killer may depend on the type of roach and the severity of the infestation. For instance, Listerine may be more effective against smaller roaches, such as German cockroaches, but less effective against larger species, such as American cockroaches.
while Listerine may have some potential as a roach deterrent, there is no solid evidence to suggest that it can effectively kill roaches. Therefore, it may be more practical to use other proven methods for roach control, such as bait traps, diatomaceous earth, or professional pest control services.
How to Use Listerine to Kill Roaches
As mentioned earlier, there is no scientific evidence to prove that Listerine is an effective method for killing roaches. However, if you still want to try using Listerine, here are the steps you can follow:
- Mix Listerine with water: For best results, mix equal parts of Listerine and water in a spray bottle. This will dilute the strong mouthwash and make it less harsh on surfaces.
- Identify infested areas: Look for areas where you have seen roaches or their droppings. These can include kitchen countertops, sink areas, and garbage cans.
- Spray the mixture: Spray the Listerine and water mixture directly onto these areas, making sure to cover all the surfaces. You can also spray it into cracks and crevices where roaches may be hiding.
- Repeat the process: Repeat the process every few days or as needed, especially if you see more roaches or their droppings. It may take several applications to see results.
While Listerine is considered safe for humans, pets, and most surfaces, it’s important to note that it may not be effective in killing roaches. And the strong smell of Listerine may attract other pests, like ants, to the treated areas. Therefore, it’s important to weigh the potential downsides before using Listerine as a roach killer.
So while Listerine may not be the most effective roach killer, it can be worth a try as a natural and non-toxic alternative to harsh chemicals. Just be sure to follow the instructions carefully, and keep in mind that it may not work for everyone.
Other Home Remedies for Roach Control
Besides using Listerine, there are other natural remedies that can be used to control a roach infestation in your home. These remedies are often safer and more environmentally friendly than chemical insecticides, and they can be effective in managing and repelling roaches.
Here are some other natural remedies for roach control that you can try:
Diatomaceous earth may be a good option to consider. This powdery substance, made from the fossilized remains of diatoms, is a natural insecticide that can be effective in killing roaches.
To use diatomaceous earth for roach control, you’ll want to make sure to get food-grade diatomaceous earth, which is safe for humans and pets. Then, apply the powder in areas where roaches are known to frequent, such as around baseboards, behind appliances, and in cracks and crevices.
It’s important to note that diatomaceous earth can take some time to work, so you may not see immediate results. However, over time it can be effective in reducing the roach population in your home. Just be sure to follow instructions carefully and take precautions to avoid inhaling the powder, as it can be irritating to the lungs.

Essential oils such as peppermint oil, lavender oil, and tea tree oil have natural insecticidal properties that can repel or kill roaches. One of the advantages of using essential oils is their non-toxicity to humans and pets. However, they may only work in small infestations and may not be effective in eliminating a large roach infestation. To use essential oils, dilute them with water and spray them in areas where roaches are known to frequent.
Bay leaves are another natural remedy that can be used to control roaches. Bay leaves work by releasing a scent that is toxic to roaches. One of the advantages of using bay leaves is their non-toxicity to humans and pets. However, they may only work in small infestations and may not be effective in eliminating a large roach infestation. To use bay leaves, place them in areas where roaches are known to frequent.
Another natural remedy that can be used for roach control is catnip. Catnip is a plant that contains a natural insect repellent called nepetalactone. One of the advantages of using catnip is its non-toxicity to humans and pets. However, it does not kill roaches and may only work in small infestations. To use catnip, place catnip leaves or tea bags in areas where roaches are known to frequent.
Here is a table comparing the different natural remedies for roach control:
|How to Use
|May damage surfaces
|Spray directly on roaches
|Highly effective, natural insecticide

While these natural remedies may be effective in controlling or repelling roaches, it is important to note that they may not be as effective as proven methods such as baits, traps, and insecticides specifically designed for roaches.
some of these remedies may have their own drawbacks, such as limited effectiveness or potential harm to humans or pets. It is important to weigh the advantages and disadvantages of each remedy before deciding to use them.
So, does Listerine kill roaches? While there is some anecdotal evidence that suggests it may be effective, there is no scientific evidence to support its use as a roach killer. However, Listerine does have some disinfectant properties, so it may be useful in keeping roach-prone areas clean.
If you’re dealing with a roach infestation, there are other home remedies that have been proven effective, such as boric acid and diatomaceous earth. It’s important to remember that proper sanitation and prevention methods are also crucial in keeping roaches at bay.
