Mice are more of an issue in newer vehicles with wire that's made on "Green" assembly lines with vegetable oil lube.
Rats seem to chew on anything that suits them.
Shawn Woods seems to lean toward Peppermint oil as a deterrent. It won't drive them out if they have an established warren and have a foodsource but they'll avoid your vehicles and homes if you use it where they aren't already a problem.
I plant spearmint and peppermint along the foundations on my home, garage, and Barns. It might or might not work but it doesn't hurt anything. It smells good when I run the weed trimmer through it too.
Dryer sheets and Moth Balls don't seem to do much.
