Mosquito Control Efforts and Standing Water

The Marin/Sonoma Mosquito and Vector Control District is concerned about the risk of mosquito breeding in unmaintained swimming pools, ponds, compromised septic systems, containers, debris and depressions that can hold water (including voids created by foundation removal).

District staff is working to identify current and potential sources of mosquito production on properties impacted by the fires. The District says water sources producing mosquitoes will be treated to control mosquito populations and minimize the potential for mosquito-borne disease transmission.

Information regarding the District’s programs, operations, materials used for mosquito control, and identification of adult and larval mosquitoes can be obtained online. The District encourages residents impacted by the fires to visit the District’s website and call the District at 1-800-231-3236 if there are questions or for additional information.
