Many holes in the grass area in my lawn. About an inch wide and about 4 to 6 inches deep. What to do to stop this digging?

[ How can I stop the pest that is digging holes in my lawn?

Hi, VanWunderlich!

Do you have any idea, what might be digging holes in your yard, please?

Thanks!

Are these tunnel openings? You may be looking at a gopher.
