Ordinance & Policy

The Board of Supervisors has adopted an Integrated Pest Management (IPM) ordinance (No. 3598) and IPM policy that governs and guides the control of pests on property owned, managed, and leased by the County of Marin. The IPM Ordinance and Policy do not apply to private property or other jurisdictions. The IPM Program uses best practices and science to protect the health of the public and the environment, to help manage our sites, minimize loss due to pests, and reduce pesticide use.
