Coyotes are known to have a sensitive sense of smell, which they use for hunting, communication, and avoiding predators. Certain smells can be particularly off-putting to coyotes, making them an effective deterrent for those looking to keep them away from their property or livestock.
One of the most effective smells for deterring coyotes is the scent of urine from large predators, such as wolves or mountain lions. Coyotes are naturally wary of these predators and will avoid areas where they have detected their scent. Other strong-smelling substances, such as ammonia, vinegar, and citrus, can also be effective at deterring coyotes.
