My RV has got little, biting black bugs. They are not fleas or ticks, but they bite like them. I asked a pet shop owner what he would do. He suggested that I try the original, yellow Listerine. He uses it at his pet shop to kill mites, fleas and ticks. I did, and it works!
I put some in a spray bottle to spray around the RV, on the dog, and on us. Yellow Listerine does not stain fabric nor is it harmful to humans and pets. One has to keep using it for a while because the eggs left hatch into nymphs. They bite too, but the yellow Listerine does kill them all.

I bought a small pump spray and filled it with Listerine. It has so many uses!
Dilute the mouthwash half and half with water and spray it around the perimeter of the area you are sitting in and the pesky bugs will keep away.
The best and least toxic way to rid your outdoor area of nasty mosquitoes is with Listerine (the original Amber colored kind.)
Put some Listerine in a small spray bottle and spray everywhere to keep mosquitoes away!
Use Listerine as a mosquito repellent. My mother told me that she uses the original Listerine as a mosquito repellent for my daughters when she has them camping with them.
