TOMAHAWK SNAKE A WAY Once you have removed the snakes out of your area, keep them away with Snake-A-Way. Snake-A-Way is the only EPA registered and university tested snake repellent in the world. It is safe and easy to apply by lightly sprinkling a 6 inch strip around the perimeter that you wish to protect. This procedure should be repeated every two or three months, especially when snakes are active. A 4 lb container will cover about a quarter acre lot.
