How Snake Repellents Work
Snake repellents, regardless of their active ingredients, rely on scent to deter snakes from entering and lingering in the treated area. Many snake repellent products use naturally derived ingredients, like essential oils, as the active ingredient. You will commonly find cedar oil, clove oil, cinnamon oil, garlic oil, and rosemary oil included in the active ingredients. You may also find sulfur and an ingredient called naphthalene.
The active ingredients intend to target the sensory organ of snakes, temporarily interfering with it and causing the snake confusion or fear and hopefully the snake will retreat because of this reaction. It does not hurt the snake and the reaction will dissipate.
Snake Out is a specially formulated dust that uses natural ingredients to effectively repel snakes near living areas. The product poses no threat to children or pets, and yet contains active ingredients that snakes find unpleasant. When snakes come into contact with Snake Out in the air, an escape and or avoidance reaction is triggered so the snakes are actually repelled away from the product. Apply a barrier of Snake Out at least a foot wide on the inside crawlspace foundation walls and into cracks, holes and entry points into the structure. Snake Out can also be applied under covered porches, outbuilding and sheds where snakes may harbor.
