As a former vet tech and public health weenie, it's not what an animal eats that passes rabies. It's what tries to eat the animal.

Mothballs sound like a good idea. I tried them on the squirrel in my attic. They didn't bother the squirrel, but I'll bet he had fewer fleas than most of his pals. I don't know if predator piss works onfor skunks. They sell the stuff in places where you get hunting equipment. Coyote pee, wolf pee, mountain lion pee. I don't think you have to use so much that humans can smell it.
