Mildred from New Mexico writes with a question I’ve received on several occasions:
I was told that the most effective way to combat gophers is with snakes. Is it possible to introduce garter snakes into my back yard? Have you ever heard of this solution to the gopher problem and do you have an opinion on this matter? Is there a way to “direct” the snakes to the gophers? Where does one obtain a garter snake?
Mildred goes on to say that she isn’t sure that New Mexico’s climate can support garter snakes, but in fact there are eight species of garter snake in that state — New Mexico is actually tied with California for the most garter snake species in the U.S. Now that doesn’t mean that every spot in New Mexico is ideal for garter snakes, nor that Mildred’s back yard is suitable garter snake habitat.
And garter snakes are not the best predators on gophers. While several garter snake species can and do hunt rodents, gophers are more than a little on the large side. A lot of people use “garter snake” to refer to harmless snakes in general, but the common striped snakes we know and love won’t do any good against gophers. What Mildred really wants is a bullsnake or a gopher snake, which specifically target pocket gophers. Bullsnakes and gopher snakes are essentially the same snake: the bullsnake is the large subspecies of gopher snake found east of the Rockies. They’re found all over New Mexico.
