Why do I have small holes in my yard and how can I prevent them from appearing?

Small holes in your yard are likely caused by burrowing animals such as moles, voles, or gophers. To prevent these holes from appearing, you can try using repellents, installing barriers, or setting traps to deter these animals from digging in your yard. Regular maintenance and keeping your yard clean can also help prevent burrowing animals from making a home in your yard.
