How would it work if used some canned dog or cat food, watered it down, then put that on ground, letting it soak it? The other animals could eat the pieces on ground, but the scent would remain. Sorta like the stuff they make for deer, that you actually stir into soil, makes the deer keep coming back, digging & licking the dirt. Or, just stop at local KFC or McDonalds for a bucket of old grease from the fryer.
I bought the auger last year and need to put it to work.One thing I do to target coyotes specifically is use a 2 1/2 auger on a drill and drill holes 15 inches deep. Fill the hole with liquid bait then solid bait. It reduces loss from birds dramatically due to the need to dig to reach it. Coyotes are attracted to fresh digs and the liquid soaks in the dirt for a lasting effect.
