 Our Mouth Out product actually has peppermint oil and a predator scent in it. So you can't detect it, humans can't detect it, but it deters rodents in four ways. The scent, the taste, the touch, and the predatory fear that's in the product itself. So mice smell it and they literally run the other direction. They've seen it in testing happen. And it's 92% effective to keeping mice out of vehicles.
