Skunks dig to feed on insects, particularly on grubs. Skunks will dig
up lawns and gardens searching for the insect larvae. They leave cone-shaped,
divet-like holes, three to four inches in diameter and may also turn
over larger pieces of sod. Removing their food supply usually causes
them to go elsewhere. This includes applying grub controls (Merit)
and removing other possible food sources that initially attract the
skunks to your property.
