BTW, I don't normally suggest anyone trap coons as a routine matter (some do, but I don't). BUT, once a coon has had success, they may not give up so easy and it may help to snuff that one so it can't come back. For coons who have been bad, in addition to an electric fence. Belt and suspenders, so to speak.
This thread goes about what you are up against with coons, and as for traps and trapping, explaining how to do it. Best trapping option for coons is not a live trap, but a dog proof coon trap.
