Mouse-X is a non-toxic rodent bait that kills rodents without harming any other species. Mouse-X is made from 100% natural ingredients, it can even be used inside food handling facilities. The mice will eat the bait like a food source and Mouse-X will cause dehydration. Mice have stomach sensors that tells them when they are thirsty. When they eat this bait, it turns off their stomach sensors and it can no longer tell their brain to drink water. They have no desire for drinking water. So they will just go back to their burrow, and begin the cycle - dehydration, failing kidneys, coma and then death. It is a great product to use around animals and children because it is safe and non-toxic. Mouse-X can also be used as a refill for existing bait boxes.
