As no control methods, apart from shooting and leghold traps, are legal in Southern Ontario, field trials of lithium chloride and bone oil ("Renardine") were carried out between 1991 and 1998. No effect could be demonstrated with lithium chloride. Between 1994 and 1998 bone oil was used as a repellent on seven different flocks, either directly onto the sheep or as a perimeter barrier round pastures. As long as the treatment was maintained, repulsion was achieved. The coyotes continued to kill in the surrounding area. If the odor level was not maintained, the coyotes would return to kill in the trial flocks. A slow release method for perimeter treatment was tried.
