Never discard edible garbage where fox can get to it. Secure garbage containers and eliminate their odors. Use a small amount of ammonia or cayenne pepper in the garbage to discourage scavenging. Restrict use of birdseed. Fox are attracted to it and to the birds and rodents that use the feeder.
Foxes den only during breeding season.
If you cannot wait that long, any kind of disturbance, such as loud noises and human scent, will likely cause the vixen to move to another den. Once she is aware of the danger, allow her the opportunity to move her young without threat of harm. Make sure the henhouse or other enclosure is well protected. Use heavy- gauge mesh wire to cover up holes in the structures and keep out most potential predators. Since foxes can climb over or dig under fences, a completely closed-in structure is best.
