I have a 2 part question-what’s digging up my yard? And how do I get rid of them? I have dealt with gophers for years - these are NOT gophers. Throw up mounds as large as a gopher mounds, but not crescent shaped and no obvious plug. They have just below the surface elevated runs between mounds, like a mole, but these critters must be huge! Some mounds as much as 12 inches across and 5-6 inches high. What is digging and how to I exterminate them.
