Peppermint oil, you can buy it at GNC or a health food store. I put a water bottle capful in all compartments and about 3 in the cab itself and all cabinets. It smells great & the mice must really not like it. I tried everything prior to this & nothing else worked! Try it if you have a problem with them.
