What Are They Looking For?
Foxes do not dig up lawns for fun; they are hunting. Beneath the surface of your grass live earthworms, leatherjackets, and chafer grubs. A fox's hearing and sense of smell are so acute they can locate a single grub wriggling in the topsoil and will dig a deep, messy hole to extract it.
Why Do They Target New Turf?
Newly laid turf is incredibly attractive to foxes. The topsoil is loose, soft, and heavily watered, making it very easy to dig. Furthermore, the turf rolls are often full of rich organic matter and earthworms brought in from the turf farm.
Deterrence Strategies
- Scent Repellents: Foxes are highly territorial and sensitive to smell. Using commercial animal repellents (or natural deterrents like heavily diluted white vinegar around the perimeter) can mask the smell of the grubs and deter entry.
- Motion-Activated Sprinklers: The absolute most effective, harmless deterrent. A sudden burst of water in the middle of the night will immediately scare a hunting fox away from your pristine new lawn.
