Mouse-X® 8 oz. Non-Toxic Rodent Bait. It is safe for pets and can be used indoor and outdoor. It kills rodents without harming any other species and can be used inside food handling facilities. Mice will eat the bait like a food source and it will cause dehydration. 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 rat's 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.
