Gophers moved on to a friend's acreage when the land behind was scarified for a golf course. They had to go somewhere. He got a weasel and turned it loose. Those things kill just to kill but it either killed the gophers or they moved out. When my son was 5 I taught him how to snare a gopher with a string around the hole. It was hilarious after he caught one. He was afraid of strangling it so there he was running across the prairie with a gopher running ahead of him still on his "leash". It suddenly dropped dead, or so my son thought. He was inconsolable. I'd tied a slip know so I released it and told my son we'd stand over here, away from the gopher. One eye opened then suddenly it was up and scampering back to it's hole much to my son's relief.
