Get a hound!

There is really no way to control a wild animal. I'd be willing to bet beacuse you got lots of coon pics that you are set up over bait. Am I correct? If so you may want to consider setting up on the travel routes to to bait. You won't get as many pics and this may not totally cure the racoon situation but at least you won't be set up where the coons are hanging out. You could burn up a roll of film in just a few hours with a coon on bait.

If you can see the runs they are using, set up near (20 yards of less) from the bait and catch them as they pass by. This will also help to keep down the # of pics you get from the same deer(no more 24 pics of 1 doe and her 2 fawns)
