Gophers?

Gophers are ground burrowing rodents that can become a big nuisance, especially if you've invested any time or money into beautifying your properties with valuable landscaping and/or plants. Being herbivores, they'll eat a wide variety of plants, roots, bark, stems, fruits, and vegetables. These guys won't give a second thought before turning your efforts into their personal all-you-can-eat salad bar.
A sure sign of a gopher presence is their trademark mounds of upturned earth. Generally considered an eyesore, these piles of dirt can serve as a warning sign of imminent danger to nearby plant life.
Many Phoenix area communities have large grassy community common areas. Over time, gophers' digging and eating can slowly transform these spaces into pock-ridden terrains.
So, before the feast commences give a call to the Gopher Guys and we'll give 'em the boot.
