I have posted it many times before...I use a product called Mouse-Free. It works 100% as they say. We had mice the first winter. I sprayed it over the summer/early fall and have had no issues with mice the last 2 winters. I park my camper in the same spot each year. My daughter parked her camper next to mine 2 years ago and she had mice in the rear bumper. They ate the sewer hose! Dryer sheets don't work.
