I use lure/urine and old roy can dog food, mixed in some blue-cheese dressing once. Copied that off a kentucky mountain coyote/cat trapper, he hammers coyotes with that recipe, also uses cheap hot-dogs & blue-cheese dressing.
I use a small auger on a mikita 18volt drill, drill in 3-4 holes around your dirt-hole set, teaspoon of bait in each hole. Gets them in the ''I'm going to get my belly full'' mode and get caught.
