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.


Might be skunks. They can scrape up chunks of law looking for grubs.

I guess that the skunks out west might have different habits than the
ones from around here -- ours tend to dig single holes and most are
nearly conical and a few inches deep. The photo seems, to me at least,
to show long distributions of the sod. This would suggest something
burrowing. Hard to tell since the picture is at a bad angle. Taking a
long sharp knife to the sod between two humps would probably reveal
something or other...

Skunks would have been my first guess too. They dig up grubs. Maybe
neighbors lawn was treated for grubs.
