Too often, the sun and fun of summertime is accompanied by dreaded swarms of mosquitoes that come out to feast on animals, including humans. Mosquitoes can leave you with itchy bites, and the need to swat at the annoying insects constantly can make your time outdoors miserable. If you hate the smell of insecticides and store-bought repellents, you can try to rid yourself of these pests by using Listerine, which will leave behind a much fresher and minty smell.

Step 1

Fill a spray bottle with one cup of Listerine. Original yellow Listerine works best for this; avoid generic versions with bleaching agents. Listerine can be found at drug stores and supermarkets.

Step 2

Spray areas where mosquitoes are numerous with a misting of Listerine. Make sure to spray all nearby surfaces, and spray the air as well. Allow five minutes for the Listerine to dry on surfaces.


Step 3

Spray your skin with a light mist of Listerine to keep mosquitoes from biting you. Allow the Listerine to dry on your skin for a minute, and reapply as needed if you notice mosquitoes starting to bite again.
