I trap here in NM and use skunk as the key ingredient for my coyote bait. There is an outfitter named Ray Milligan that makes a scent called stepinwolf #1 & #2 they work for coyotes,fox,and bobcats. Look him up those are the best baits I've used other than my own.
I realize your original pm was sent a few years ago but I thought I would respond to it because sources of information is so rare for coyote trapping. I live in northern Utah and will attempt trapping Coyotes for the first time since 1979. I am wondering if you have info on coyote trapping areas that you are willing to share.
Thanks and best regards.
Here are some tips that I have about trapping coyotes. The only things you currently need to trap coyotes in Utah is a trapping tag number that costs about 10$ at the DNR and you need a tag on all your traps. Other than that you don't need anything else because coyotes are not managed by the DNR.
