Does Listerine Repel Mosquitoes and Why?

The question of whether Listerine deters mosquitoes effectively is up to date now. People think they kill insects whent repelling them. “Does Listerine work on mosquitoes by killing them?”.

It might be sort of surprising, but Listerine doesn’t kill – it only repels insects, due to its containing some special ingredients.

The very first reason for that is that Listerine contains alcohol, namely the fumes of alcohol. In the research by Olimpia Ferguson, provided by the Ohio University, it was claimed that the alcohol is effective against bed bugs. However, alcohol is also a way to kill insects, spraying it directly on them, which may keep them away on an instinctive level.

Anyway, alcohol is not the only reason why mosquitoes are away after you repell Listerine. The major ingredient in the war with pests is Menthol or Eucalyptol. These oils are often used in different regular repellents, and help keep pests away. The National Pesticide Information Center mentioned these oils in their statement about repelling remedies. So, the answer to the question “Does Listerine repel mosquitoes” is “Yes”.

How to Use Listerine to Repel Mosquitoes?

More users have learned about the opportunity to repel insects with Listerine, so they became enthusiastic trying to find more ways for repelling insects with it. Does Listerine keep mosquitoes away? Yes, but you need to know how to use it.

The very first, which became a classic one, was just pouring the mouthwash remedy on a surface that you want to protect from pests. This way was originally described by the Facebook user who initiated the Listerine issue.

However, some people came further and started using Listerine as a spray. They spray around some amount of remedy in order to make mosquitos fly away. This method is way more pleasant because you will always smell the aroma of fresh mint.

Some users also claimed that they used Listerine as a body spray for repelling insects, but this way is not recommended, due to the fact that Listerine is based on alcohol, which would dry your skin and may cause some allergic reactions.

Is It Effective, Though?

The community of people who have already tried Listerine to get rid of mosquitoes is massive enough. Some claim this method is fully ineffective, referring to different research and their own experience, while others say that Listerine deters mosquitoes. So, does Listerine keep mosquitoes away effectively?

In fact, Listerine is not that effective against mosquitos. And there are several reasons why.

First of all, the amount of Menthol and Eucalyptol in it is too low. Due to the information provided on the official Listerine website, the concentration of these oils makes only 0.04% of Menthol and 0.09% of Eucalyptol. This is not enough to provide full safety from nasty pests, though.

Moreover, the alcohol, which also might help against insects, quickly vaporizes, which will not give you long-lasting protection. For this reason, if you are going for a walk to some park or forest, the best way is to use different certified repellents, which would be much more effective and long-lasting, according to the Centers for Disease Control and Prevention.
