A few years back the little bastards found the feed in my barn. Instead of ripping open 1 bag and eating from it they ripped open every one that was exposed (15 or so). Crapped and pissed everywhere.
2 live traps have thinned them out considerably. A sprinkle of cat food lures them inside. WV coons have not wised up yet. Interestingly though, this year has mostly seen young ones.
Fly bait mixed with grape juice works wonders. Critters drop within 5 feet of the dish. Problem is it kills indiscriminately. Fear for local pets has kept me from using this method although others find it very successful.
The magazine Fur Fish and Game advertises a trap that catches the coons front leg as he reaches in for the bait. IIRC ad states it is pet safe. I may give one a try someday.
