Live trap with fresh bait. I like to use cat food and tuna(cheapest I can find), also table scraps like a leftover fired chicken leg. I have heard people having good success with marchmallows and dounuts.
I weigh down my trap and put stuff around the sides of it so they can't reach in a get the bait through the wire.
Whenever I dispatched on I use to wash up the trap real good to get the blood off. Then one time I didn't have much time so I dispatch the varmint and reset the trap with no washing it and no bait inside. I caught another coon the that night. So I no longer wash blood off the trap and if it gets really bloody then will forgo the bait too.
