Found this post from March about the same topic. There's some good information in that thread.

My dad had an old book of tips for bait making. You gut the hogs. Chop em into walnut sized pieces. Place in jars with lids loosely screwed on. Bury in a cool shaded area under trees etc. Leave them there for about three months. Pull em out and use it as bait.

I used this recipe but with snowshoe hare meat. I tell you, it worked wonders. It was tainted, but not rotten. When I bought my first commercial coyote bait a few years later, I opened the jar and took a whiff. I could swear it was the same thing. Last year I bought some bait. Opened the jar, same thing, smelled exactly like the bait I made that time 30 years ago, following a tip from a book my dad had from the 50s. Lol

If I trapped more and snared less, I would be using this method exclusively. Far cheaper than buying the same thing for what a quart jar would cost. Up here bait costs in that 20 dollars for a cup range. So a quart would be worth at least 80 bucks... Amazing how scent stays a memory for so many years!

Give that a shot.

Back in the '80's a fellow by the name of Red Edgemon recommended groundhog or housecat for predator bait. I got some groundhog and Grawe's bait solution and had a real good year (especially for a beginner) on grey fox primarily. East TN didn't have very many coyotes at that time and bobcats were scarce also.
