Enta Snake powder is composed of finely milled fossilized shells of minuscule organisms called shell powders. The microscopically fine, sharp edges desiccate the snakes' moist exterior skin upon contact and the snakes will dehydrate and die within 12 to 36 hours. The snake will also die when they eat the dust.
Sprinkle a light layer where snake frequents, including sinks, sewer pipes and drains and in cracks and crevices. As long as the powder remains in an area, any snake that gets to it will be killed.
