Managing Noxious Weeds

The procedure to control noxious weeds depends on the species of weed, the habitat, the surrounding environment, and the availability of equipment, materials and personnel. Eradication and restoration require that weeds be killed. Their very nature make that difficult, for they are invaders by nature and do not succumb to control except at great cost.


Learn how to help lessen the spread of noxious weeds in Idaho.
  • Avoid driving in noxious weed infested areas. Seeds can become stuck in tire treads or mud on the vehicle and be carried to unaffected areas.
  • Don't transport flowering plants that you cannot identify.
  • If you find a small number of isolated noxious weeds that have no flowers or seeds, pull the weeds and leave them where you found them to dry out.
  • If you find noxious weeds and they have flowers or seeds, pull them, place them in a plastic bag or container to avoid spreading seeds, and either burn them or dispose of them in a sanitary landfill.
  • Report newly-found noxious weeds to the county weed superintendent or county extension office. If you need help in identifying new weed, visit the Identifying Noxious Weeds page.
