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.

That looks like classic Badger damage to me!

Do you have Badgers there?

Nope. Never saw any unless they are hidden! Wait, do badgers exist in
Southern California?
