https://i.imgur.com/GUHwN5A.jpg from a local rural So(uthern)
CA(lifornia) house. Gophers? Deers? Dogs? Squirrels? I doubt it is the
ants even though there are Red Imported Fire and Argentine ants' mounds.

The next door neighbors' lawns don't even have this problem. What is
missing and how to stop these dig ups?

Thank you in advance.
