I've never had luck with scented stuff, mothballs or bitterants. Heck I had stuff I had put mint oil on as well as bitter apple eaten only where it was applied. I put wasabi mixed from powder out and they ate that too.Fresh Cab is great against mice and smells nice. If you don't mind pepermint, buy pure peppermint oil and bless the inside of the truck. We have lots of field mice and had a motorhome parked outside for 8yrs, never once had anything inside chewed through.
