When used as directed, MouseX Pellets are effective for indoor and outdoor mouse and rat control, even 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. MouseX works from the inside out to exterminate mice and rats, then dries them out after death to reduce odor by as much as 90%. Formulated using naturally derived ingredients, MouseX Pellets attract mice and rats with their scent and taste when used as directed. Once ingested, active ingredients in the pellets coat the mouse and rats stomach lining, blocking all messages from the stomach to the brain. This causes mice and rats to stop wanting water, leading to eventual dehydration and death.
