I just SOLVED my 4-legged bastard problem. It's called "shake away," and while the box I got didn't list ingredients, the main ingredient is COYOTE PISS. They come in little bags that you hang in the front and back yards (to make them feel they are being stalked), and within 2 days your yard will be deserted. I tried everything before that: moth balls (crock of shit/old wives' tale), mouse traps, havaharts, cat pee, pepper spray, etc.

Shake-away. Those fuckers are GONE.
