When I called Western Exterminators, they told me quite honestly that pocket gophers are hard to eliminate. Their standard service is to set poison bait in the gopher tunnels, wait a week, and then return to set bait again. They couldn't offer a guarantee. Nevertheless, I was having no luck on my own, so I agreed to the standard service. When I returned home from work on the day of the first visit, I saw several landscape flags in my lawn that indicated the places where they had inserted bait into the gopher tunnels. I also saw dirt flying through the grass as the gophers began to dig anew. Oh well, I thought: they said that this might not work. Maybe they'll eat the bait next time. The following week, Western Exterminators returned for round two. That was four weeks ago and guess what? No evidence of gophers! I appreciate that Western Exterminators was honest with me about the challenges of gopher infestation. Sure, I feel bad for the little buggers, but I don't miss raking piles of heavy clay soil out of my lawn and landscaping. I certainly recommend Western Exterminators to my friends, neighbors, and readers of Angie's List.
