Fox Evictus is a natural glandular by-product of predators, which are threats to fox pups during the denning season. The adult fox senses that a danger to their young is nearby, inspiring them to move the den location and pups. Use 2 ounces per den site. Place in a perimeter around yard or den site. Scent mark at multiple sites like fence posts bases of trees. Shake before each use. Available in 2 or 4 Ounces Bottles.
