Do peppermint oil or dryer sheets keep mice out?
Not reliably. Pest control companies describe peppermint as a short-term deterrent at best, and the scent of dryer sheets fades in a short time. What does keep mice out is sealing gaps, because Health Canada says a mouse can get through a dime-sized crack. For mice already inside, Pipestone Farm Supply carries traps that remove them.
