Spraying Update

The Sacramento-Yolo Mosquito and Vector Control District’s primary goal is to protect public health and welfare by managing mosquito populations so they do not present a risk to our community. If mosquito populations pose a significant public nuisance or when emergency control measures are needed to rapidly disrupt or terminate the transmission of disease to humans, the District will respond by continuing to implement its Mosquito and Mosquito-borne Disease Management Plan. As part of this plan, the District may administer Ultra Low Volume (ULV) treatments by using backpack foggers, hand sprayers, truck-mounted foggers or aircraft, in and around areas where virus activity has been detected. Each fogging unit’s output is calibrated to ensure the correct amount of product is applied for each treatment area. All products are registered with the California Environmental Protection Agency (EPA) and are applied by trained and state-certified technicians. Adulticides are chemicals that quickly reduce adult mosquito populations. Larvicides target mosquitoes developing in the water.

The District strives to keep the public updated and informed on all mosquito control treatments to protect public health and welfare from diseases such as West Nile virus among others. Residents are encouraged to sign up to receive email notifications for urban, agricultural or ground treatments occurring in their zip code.


**Any scheduled treatment may be postponed, cancelled or rescheduled due to unfavorable weather conditions and/or other reasons**

Routine Aerial Spraying to Agricultural Areas

  • The District conducts routine aerial applications to a variety of agricultural sources that may be producing mosquitoes. Agricultural areas that may be treated include areas such as rice fields and pastures.

  • IMPORTANT NOTE: At times when agricultural treatments are being conducted close to residential areas, the plane may fly directly above homes. Material is not being deposited below, rather it is targeting a specific location. For additional information relating to this topic, see our Spraying Frequently Asked Questions page.

  • Typical agricultural aerial spraying times are between 8:00pm and midnight.
