Coyotes are a natural predator of white-tailed deer; and as such, deer become apprehensive if they feel that coyotes are nearby. This is why Deerbusters suggests that homeowners use Shake Away Coyote Urine Granules to make deer think that coyotes are closing-in on them. When whitetails pick-up on the scent markers from the granular coyote pee, they will adjust their grazing and traveling patterns to avoid these areas. This organic and non-toxic granular coyote urine formula can be spread directly on the ground where deer may be wandering. While Coyote urine is meant to repel deer, it can also repel elk, armadillos, and feral pigs.
