the beer bottles and the vibration stakes will work for a little bit, but once they get accostomed to it they will be back. The only true fire way to get rid of them is with traps. then once you kill them off others will move in. It will be an uphill battle. you have to hit them hard and stay on them. Also when you purchase trap also purchase traps for pocket gophers. I actually had both in my yard and I wondered why I couldnt trap a few of them. Finally my wifes chihuahua's dug one up so I could get a look at one...... I also made a pvc contraption that would dump bleach and amonia down into thier runs. When the two are mixed it puts off a harsh gas. It seemed to work for a few weeks but once they came back it seemed like they tunneled in more areas. So I dont think it was that effective. I wish you the best,I waged war on them for years and I never got rid of them.
