If your not particular about how you get them, consider traps or snares (if legal there). If they are heavily called there, you will need to try a differant sound. Go to the autoparts store and get a roll of the transparent, red tape they sell as a temporary fix for broken tail lights. Try that over the lens of your spot light. Watch the wind and try to set up where you can see, but they can't circle around down wind of you. Keep your motion to a minimum. Consider getting the sound away from you if. A decoy may help if they are hesitant. One or two coyotes can leave alot of tracks, but if habitat is good they will be there.
