I'm a home grape grower with just 9 vines around my house that are all less than 3 years old. There is nothing fancy about my "setup"...most of the vines are just intended to grow up my chain link fence. I'm currently struggling with a gopher by one of my vines. I've tried a trap but he somehow manages to either fill the hole without ever tripping it or he simply abandons that tunnel and I find a new mound close by. I just tried a gas "bomb" today and am hoping that finally got the little jerk. If that doesn't work, has anyone had luck with the ultrasonic repellents?
