Using Listerine as Bug Repellent

Listerine contains ingredients like Eucalyptol and Menthol, recognized for their bug-repelling qualities. However, the concentrations of these compounds in Listerine usually hover below 1%. This minimal concentration can help for shorter periods but is insufficient for providing long-lasting protection against mosquitoes.

Note: Listerine is primarily designed for oral hygiene, not as an insect repellent.

Bug Repelling Compounds in Listerine

Here is the concentration of the compounds in Listerine. 

  • Eucalyptol Content: Listerine contains around 0.09% Eucalyptol, a compound known for its bug-repelling properties. Eucalyptol comes from Eucalyptus oil, which is excellent at keeping pests and mosquitoes away.
  • Menthol Presence: Menthol, another bug-repelling compound found in peppermint, is also found in Listerine at concentrations of approximately 0.04%.

With their subtle concentration, Eucalyptol and Menthol in Listerine contribute to its repellent nature, although the effect is limited compared to dedicated insect repellents.

Using Listerine to Repel Mosquitoes & Flies

Listerine’s bug-repelling effects are short-lived. Due to its composition of alcohol and water, Listerine tends to evaporate quickly when applied to the skin. This limits its effectiveness compared to traditional insect repellents designed to provide hours of protection.

However, you can still use it to eliminate mosquitoes and flies in your home and garden. Here’s how to use it.

  • Spray Around: Use a spray bottle to put Listerine around your garden. Spray it on plants and near sitting areas to help keep mosquitoes away.
  • Make a Mix: Mix water and Listerine in a bucket. Then, pour it on the ground in the garden.
  • Dab on Skin: You can put a bit of Listerine on your skin if you do not have any other remedy handy. But be careful, don’t use too much. It will help keep mosquitoes from bothering you while you enjoy your garden.
  • Refresh Regularly: Listerine wears off quickly, so refresh it occasionally. A fresh application could keep mosquitoes and flies at bay for a while.

Note: You should know that these steps only show you how you can use Listerine to repel bugs temporarily. It is not recommended to do so.
