Due to elevated mosquito abundance, Northwest Mosquito and Vector Control District (NWMVCD) will be conducting a wide-area adult mosquito control application on July 3rd, 2024. The spray application will be conducted between the hours of 3:00 a.m. to 6:00 a.m. at the following location: the City of Eastvale along the bike trail located next to the Santa Ana River. Please see attached images for exact spray route. 

NWMVCD will be treating this area with Aqua-Reslin (EPA Reg.#432-796) on July 3rd, 2024. This control product has been approved for use in mosquito control by the US EPA.  We’ve dedicated significant efforts towards implementing Integrated Vector Management efforts within this area. Our primary focus of control is to target the immature mosquito in the larval stage of its life cycle before it matures into a flying adult. Signs will be posted on July 1st, 2024, within the neighborhood to notify the public of our activities.  Information regarding the treatment will be posted on our website at If there are any questions or concerns, please contact NWMVCD at 951-340-9792.
