What kind of gophers are giving you problems and what do they do that is the problem.
In this country we have something that digs up the dirt in the hayfields and pastures. They are called, moles, pocket gophers and lots of nasty names. Everyone has different opinions on just what creature is doing it. They dig in pastures too, but that isn't much of a problem. They are one of the reasons I quit putting up hay.
I've been mowing and stopped to go to dinner and come back and they have already had mounds built up in, on and over the hay that I'd cut less than an hour before. I've seen a mole and the cats bring in a short tailed things that looks like a mouse, only bigger. We have striped gophers, but I can't see any harm in them.
My brother brought a hound cross of some sort one time and left him here when he left. He was only good for two things, getting mice and killing hand raised pheasents. Dad finally had enough of him and took the shotgun to the field one day. Funny, I never saw that dog again!
