Foxes normally use abandoned burrows, hollow trees, and rock piles as dens, but sometimes a fox will den and give birth to its young under a porch, deck, or shed. If possible, allow them to stay until the young are two months old and begin accompanying the adults on hunts.
If you need the foxes to move sooner, then you should encourage them to move out by:
- Making loud noises
- Playing loud music near the den
- Using strobe lights and/or motion sensor alarms
- Using repellents, such as soap shavings, vinegar, commercial fox repellents, or coyote urine
If there are young present, the adults will need time to locate an alternate den and return to remove each pup.
Once the den has been abandoned, close the entrance with rocks, logs, or bricks. Bury 1/4- to 1/2-inch hardware cloth a few inches below ground, 12 feet around every potential entrance.
