Wide-area Mosquito Sprays Planned for Cities of Eastvale and Norco

May contain: neighborhood, outdoors, intersection, road, and city

Due to the detection of West Nile virus (WNV) activity and elevated mosquito abundance, the district will perform adult mosquito spray treatments on August 11th., 2023 to lower the mosquito population affecting recreational and residential areas along the Santa Ana River in the Cities of Eastvale and Norco. The spray application will be conducted between the hours of 3:00 am to 6:00 am at the following locations: the Prado Basin Park Rd. and Kendra Ln. in the City of Eastvale, Santa Ana River between River Rd. bridge, and the Santa Ana River bluff area parallel to Norco Dr., between 5th & Hamner in the City of Norco. Please see attached images for the exact spray route.

The district will be treating these areas with Aqua-Reslin (EPA Reg. 432-796), which is approved for use in mosquito control by the US EPA. We have been working hard to use Integrated Pest Management Practices in these areas, and the majority of our efforts focus on preventing mosquito breeding and killing mosquito larvae before they become flying adults; However, due to an elevated abundance of adult mosquitoes testing positive for WNV within these areas, we have decided that adult mosquito control via truck-mounted ground fogger is our best means to control the current mosquito populations in these areas. Signs were posted on August 9th., 2023 in the areas affected by our spray application. Information regarding the treatment will be posted on our website at www.northwestmvcd.org. If there are any questions or concerns, please contact the district at 951-340-9792
