When my dad is just trying to catch coons, his favorite trap is the Duke Dog Proof trap... Stuff some cotton laced with a tasty scent like clam juice or rasberries down in the trap. The coon reaches in and wham, his leg is caught. Nice thing about them is you don't have to worry about nailing a dog, fox or other animals. Any of the traps used for foxes will nail coons too. My dad ends up catching far more coons than foxes. Coons love the smell of fox pee and will come over the check it out and get whacked.
