  • Jefferson County Weed and Pest Management


    The Jefferson County Weed and Pest Management program helps the public by developing integrated management plans to control mountain pine beetle and noxious weeds. The program, which includes working with the Jefferson County Open Space Natural Resources section, coordinates with other governmental agencies to achieve regional pest control.

    This site includes information to help identify, control and prevent mountain pine beetle and noxious weed infestations. Our goal is to educate the public about weed and pest problems and offer solutions.

    Purge Your Spurge

    Myrtle spurge, a List A noxious weed must be eliminated anytime it is found.  It had been planted as an ornamental until 2003 when it was added to the state's List A Eradication list.  It is spreading into natural areas where it takes over and crowds out any other plant.  Please refer to our fact sheet for more info.
