A suggestion that spraying Listerine mouthwash around your property will keep mosquitoes away.
There is no documentation that Listerine mouthwash is a good mosquito repellant. The writer of the email fails to identify who he or she is or where this took place so there’s no way of verifying it.
TruthOrFiction.com contacted the folks at Johnson and Johnson, the makers of Listerine. They said there has not been any research on the effect Listerine might have on mosquitoes. All of their testing has been on germs, such as in the mouth.
