Protecting California's agricultural industry, natural resources,
and the health and safety of residents and workers

The Pesticide Use Enforcement Program protects the public, pesticide applicators, field workers, and the environment through education and the enforcement of state and federal laws and regulations.

Department Biologists:

• 
  
• provide information and training to workers, growers, applicators and homeowners on the safe use of pesticides;

• monitor pesticide applications at both urban and agricultural sites to ensure they are performed in a safe and effective manner, and that worker safety requirements are followed;
  
  
• inspect application equipment, pesticide storage sites, employee training documents and business pesticide use records;
  
  
• investigate complaints and pesticide-related illnesses

The Pest Exclusion Program provides the first line of defense for California's agricultural industry and environment from the introduction of exotic insects, weeds and plant diseases that "hitchhike" in from other states and countries. Incoming shipments of plants and produce arrive at various locations in the County including San Francisco International Airport and wholesale nurseries where they are inspected for harmful pest and diseases. Shipments of agricultural commodities destined to other states and countries are inspected and certified for compliance with quarantine requirements.

This proactive program is designed to detect pests before they become established. Insect traps are placed throughout the County to catch exotic pests such as medfly, gypsy moth and Japanese beetle. Early detection and eradication of harmful pests protects California's agricultural industry, home gardens, parks and natural resources and reduces the need for pesticides.

The Agricultural Commissioner provides administrative support for the San Mateo County Weed Management Area (WMA). The WMA is a regional coalition of agencies, private landowners, the agricultural industry, and environmental organizations concerned about the proliferation of invasive plant species in the County. The WMA promotes and coordinates efforts to prevent the introduction, establishment and spread of noxious weeds.

A Biologist is available Monday through Friday in the afternoon at the main office (728 Heller Street, Redwood City) to assist homeowners and pest control businesses with the identification of landscape, home and structural insect pests, weeds and plant diseases. Effective control methods are recommended with an emphasis on integrated pest management.

The Department maintains a referral list of licensed pest control companies that will provide animal trapping services for county homeowners experiencing problems with skunks, raccoons and opossums. Information on other methods of wildlife damage control is also provided to homeowners.
