The Custer County Weed & Pest Board and Custer County Weed & Pest Department are committed to the implementation of an effective integrated Weed & Pest Management Program.
Our goal is to control and monitor local and state noxious weeds and declared pests within Custer County. Custer County Weed and Pest Department is overseen by the County Weed Board which meets at least four times per year. The Director informs the Weed Board on activities of the Weed Department.
