Run a ferret through your ventilation system every couple of
weeks!  Rodents are terrified of even traces of ferret smell.

I bet Bill Killian doesn't have mice or rats in any of his VW's
(since he uses them for toting hordes of ferrets).

Let me know where you live--maybe I have a friend with a ferret
nearby.
