you need one of these....
good luck with them city coon....about the best option is to live trap them and haul them to the woods elsewhere....my favorite bait for city coon is peanut butter and jelly sandwhiches...cheap peanut butter and jelly globbed on the bread thick n heavy....found it works great for coon and keeps cats and such out of the traps...coon lure also helps fool them....sprinkle it on/in the trap and leading in the entrance. brushing it in also helps....wish i could tell you how many city coon dad and i trapped with that technique for training/nusiance coon control.
but, i dont know if you'll beable to get them all. best bet is to try that and also start securing the garbage better...shootin them with a bow in the city just dont sound smart to me....
