I have a running battle/war going on with coons too. In Ohio if you have a fur taker permit and they are a nuisance you can kill them year round on your place.
I like the dog proof coon cuffs with the Ztraps being my favorite baited with little marshmallows. The trouble with coons is they are like a hydra...kill one and three come to it's funeral.
I trap/shoot them from mid winter until late august then lay off because I don't want to spook the deer.
