I bought this annoying beeping underground stake and some pellets at my local home depot, they moved to the complete other end of the street (and i am on a corner also).

Just ordered traps called gophernator - neighbor has some and has caught quite a few in the past few weeks. Company is out of California called trapline. We have gophers and they have taken down a 6' rose and large Mexican bird of paradise this week. My plants will be revenged!
