Snake-A-Way is the world's only EPA registered, university tested, patented snake repellent. It has been proven effective against both poisonous and non-poisonous snakes. When used and applied as directed, it is environmentally friendly to humans, animals and plant life. It has been universally approved and endorsed by naturalists, conservationists and ecologists. In use, the granular product is spread on the ground across an area where it is desired to prevent or discourage snakes from entering. Preferably, the granules should be spread in a strip 10-30 centimeters wide, although generally the wider the strip the better. In this manner, an odor barrier is provided that snakes are reluctant to cross.
