Before they get educated, put a couple dozen or more traps spread out in a quarter acre area around a deer feeder that only has a few days of food left in it. Bait traps full every couple days but don't set the trigger. A week later, once the deer feeder has been out for several days, set the traps and fill half way. You will catch way more coons like this than putting a few here and a few there and letting them get smart. If ants are giving you problems, spray a strong solution of permethrin around the traps. Kind of like pigs, need to take care of as many as possible at one time then move to another spot.
