You can sprinkle coyote or fox urine on the ground. You can buy it at garden stores or farm/garden shops like WILCO in Oregon. I take old panty hose and make golf ball sized wads (tie the ends in knots) and toss them behind cupboard drawers and up around the gas/brake area. No, I can't smell them.
There's different names for it. Shake Away is sold on Amazon.
