Larimer County Weed Control District processing requests for herbicide no spray zones

Landowners who prefer not to have an herbicide applied on county rights-of-way adjacent to their property can apply for a “no spray zone” by calling the Larimer County Weed District at 970-498-5768 or apply online at

State statute mandates that all road rights-of-way be managed for noxious weeds. This is especially important because roadsides are one of the most common ways noxious weeds are introduced into areas and spread onto adjacent lands.

Larimer County Weed Control District offers services including recommendations on weed management and range and pasture restoration, herbicide sprayer rentals, herbicide sales, informational brochures and weed identification. The Larimer County Forestry Program includes expert advice on hazardous and diseased tree removal, forest pest identification, help with mountain pine beetle, spruce ips, Dutch elm disease and fire-wise planning. Site visits to help with plant identification and management recommendations are available. Call 970-498-5768 for weed issues or 970-498-5765 for forestry concerns.
