    Light Brown Apple Moth (LBAM), an invasive pest native to Australia, was confirmed for the first time in California and the continental United States in March 2007.

    The Sonoma County Agricultural Commissioner’s Office is responsible for the detection of noxious pests in the county, and education and outreach to the community and agricultural industry regarding these pests and the quarantine restrictions. We are working directly with agriculture and related industries to help them meet state and/or federal requirements to move their commodities, and to ensure their business is impacted as little as possible.
  • Marin Sonoma mosquito and vector control logo
    This program serves to effectively manage mosquito populations and prevent the spread of vector-borne diseases such as West Nile virus (WNV).  Free services include delivery of mosquitofish and inspections for other pest and rodent populations.
  • This is a proactive program to detect pests before they become established. Traps are monitored throughout the county for the presence of exotic pests of agriculture, such as Mediterranean Fruit Fly, Oriental Fruit Fly, Melon Fruit Fly, Gypsy Moth and Japanese Beetle.

Iberian star thistle has been reduced to a small fraction of its original numbers. Hydrilla, a pest of waterways was found in and eradicated from Spring Lake.
  • This provides protection to the county by regulatory control through quarantines to prevent the introduction of pests that are not known to exist or are of very limited distribution in the county.
  • The Pest Management Program protects local agriculture and the environment by mitigating the spread of insect and vertebrate pests, weeds, and diseases through exclusion, trapping and regulating the movement of agricultural commodities in and out of the county.
  • The Predatory Animal Control Program’s role is to help alleviate problems that are created when wildlife causes damage to agriculture, urban, natural resources or presents a threat to public health or safety. This program also can be utilized to protect many kinds of wildlife including endangered and threatened species from predators.
  • The function of this program is to oversee, monitor and evaluate the use, records, storage and sales of pesticides as required in the California Food and Agricultural Code, the California Code of Regulations and the Business and Professions Code.
