This is a really common problem in Arizona. Pack-rats get into engine compartments, chew up wires, make nests, etc.

You should be thankful that they haven't set up shop in your heater vents and made a cozy little "Casa de Raton" in there. First hint of winter, you hit the heat and WHAM! Rodent/feces smell that will never, ever go away.

Ridding your car of these isn't all that easy. They will just move to another area of your yard or garage until they get the chance to once again become filthy little un-wanted wrench monkeys.

Go to Lowe's or Home Depot and get some of those ultra-sonic pest repellant devices. Put a couple of them bad boys in your engine compartment (be sure to secure them really, really well), and a couple in your garage.

They may work for a while, but will also probably freak out your dog, cat, feral neighbors and wife. Not that that would be a bad thing....

Poisons won't really work and will probably kill your dog, cat, feral.... n/m.

They won't go away. They will come back. They will haunt you forever. Sleep tight!
