When used as directed, RatX Pellets are effective for indoor and outdoor rat and mouse control. Safe for use around cats, dogs, and children. Place these easy-to-use pellets around landscaping, near livestock or poultry housing, or under buildings or garden structures. RatX works from the inside out to exterminate rats and mice, then dries them out after death to reduce odor by as much as 90%. Formulated using naturally derived ingredients, RatX Pellets attract rats and mice with their scent and taste when used as directed. Once ingested, active ingredients in the pellets coat the rat or mouses stomach lining, blocking all messages from the stomach to the brain. This causes rats and mice to stop wanting water, leading to eventual dehydration and death. For safe, efficient & effective rat extermination, choose RatX Pellets.
