Although feral nutria (Myocastor coypus) have been present in California since the mid-1940's, they are quite scarce and at present are causing little or no agricultural damage. Present state regulations and pest detection activities will probably prevent them from becoming a serious economic pest. Should control ever become necessary, studies in other areas indicate that shooting, trapping, and baiting with zinc phosphide should be effective.
