Pesticide Applications

Pesticides are used as a last resort after exhausting all other options. When pesticides are used, the least toxic pesticide is chosen from a list of products that have been reviewed and evaluated and an application method is used to decrease non-target exposure.

For notices of pesticide applications in the Boulder city limits and on city-owned Open Space and Mountain Parks (OSMP) lands, select the "Pesticide Applications" links below or call the Pesticide Hotline at 303-441-3400.
