The hole shape is usually a major determining factor in identifying the cause of holes in your lawn. Several animals bore different holes depending on their activity, and these holes may be in the form of burrows, mounds, and divots.
A burrow is a long, narrow tunnel dug by animals for habitation. Burrows are the most common holes left by yard or garden pests like rabbits, mice, snakes, and voles.
These are heap piles of earth, soil, debris, or sand. Animals create these holes when searching for food or shelter, and gophers and moles are culpable for digging mounds.
