We used to make our own coon attractant. We'd go catch a mess of fish, cut it all
up and stuff it in a gallon jar, put the lid on it then bury it for a year or so.
The tricky part comes when sifening out the oil on top. Didn't think of a turkey baster back then.
p.s. The smell will cross your eyes but the coons lap it up, even after being caught.
