Oregon Dept of Fish and Wildlife would disagree that fencing would be classified as a "trick" as it is the only recommended and highly successful deterant practiced in the state. I will state this again: traps catch and MAIM non-target animals Indiscriminately and only (temporarily) work if you life in an extremely rural area. "To hell with the neighbor's dogs if they are running lose" will make more enemies than it is worth and possibly buy you a law suit. If you ever figure out how to find out where the coyotes "live", please let the rest of the world how you did it.
