I've got three traps, with no idea how to use them. I don't know how set the trap up, what to use for bait, etc... I'm looking to trap fox, yotes, and bobcats. Any input would be great!

Start reading Fur-Fish-Game, it has some ver helpful articles, for the practical sportsman, but mainly focuses on fur.

what kind of traps,foothold,box traps,or body gripping.I'm no expert but you would use different technique's with each of these the input of some of the trappers would be better if they know what kind you got,I'm not a trapper but I have caught several coons in live traps for local farmers around their corn cribbs,racoons have a sweet tooth I use tuna fish and some grape jelly beside it,they like it.
