Snake Out All Natural Snake Repellant repels snakes without harming them. Snakes “taste” the surrounding air, and the special blend of ingredients in Snake Out Snake Repellent is especially unpleasant to them. When they come into contact with Snake Out in the air, an escape/avoidance reaction is triggered so the snakes are actually repelled away from the product. Snake Out Snake Repellent is made from ingredients such as cinnamon, clove and cedar oil that snakes find offensive or alarming. Snake Out comes in an easy-to-apply dust and can be used wherever snakes are not wanted, keeping them away during normal foraging behavior.
