in reference to a responder above, a cat or two...
I'd actually say get about 10 stray cats, or outdoors cats that people are not able to keep...and have them stick around, and keep up an invisible fence and limit their foodage (ie-don't buy them food, but make sure these are outdoor-friendly cats, not purebreds!lol)...the mice will be gone pretty quick...
In contrast:
an idea would be to leave stuff on the ground in the vicinity of the car, food stuff that attracts mice, set up with a trap.
When the mice are caught, bring them to an animal rescue, so they won't need to die, but they'll be out of your way ^_^
And apparently PETA carries a humane form of trapping them
go to referred site for help and details ^_^
GOODLUCK!!!!
