Identification & Problems Though foxes are known for taking over the dens of other animals, they may also dig their own burrows on private properties. Burrow entrances, also known as fox holes, are typically four inches in diameter or larger. They tend to be situated near the bases of trees or walls and may be surrounded by the feathers or bones of prey. Having fox holes in the yard makes residents susceptible to injury, as they might trip or fall into the burrow entrances. Additionally, the presence of foxes can lead to secondary infestations of parasitic worms or mites. Prevention & Removal To prevent foxes from burrowing in yards, property owners should remove their access to potential food sources like garbage cans, compost piles, bird feeders, and pet food. Additionally, individuals can erect fences around lawns. If a fox hole is found, the best way to avoid injury or the transmission of disease is to call in a wildlife removal professional. The experts at Critter Control have the appropriate tools and knowledge to remove foxes and fill in fox holes in yards.
