Wildlife Management 101 ----- Food, Cover, Water,,,,,,,Coyotes are more easily trapped (FOR ME AT LEAST) at spots where THEY are looking for something in particular first,,,, rather than ME producing something for them to look for.. Where they are hunting for food entering a pasture, crop field or frozen irrigation/creek ditch. Where they seek cover moving from 1 area to another (blind set) or where/when they are thirsty. Coyotes on the plains, will not pass up a drink of water in December when things are froze so a pond or irrigation ditch should have tracks showing this. Looking at aerials and topo maps can help but Food, Cover, and Water have helped me as much through the years as anything. An example would be coyotes entering a pasture through the farm lane gate. Once he is there its like his eyes, ears and nose have kicked up a notch as HE is looking for a rabbit, mouse, bird etc., etc.. to satisfy that FOOD element. I didn't ask him to turn those on 200 yards back along the crop edge. Provide a set close to his entry and I have had a better chance of cuffing one than along his fence line or cropland route. He already has his senses tuned when he smells my goods. So that makes him more vulnerable from my experience. You have heard the term "that's just a coyote being a coyote" in their indifference to a set, my experience has been that he was not "looking" for 1 of those previous 3 elements and my goods weren't good enough.... my take.
