We're Under Attack!

Moth balls in a sock tied under hood.
A product called fresh cab sold in farm supply stores.
Had rodent build a nest on top of a fabric softener sheet in my truck.
Irish spring soap is supposed to work too. Havent tried it.
Havent heard much about ultrasonic deterrents, too bad they dont make a 12 volt one.

Worst thing, one day one of them little buggers may cause a fire....
