The District will perform adult mosquito spray treatments on April 22nd., 2021 to lower the mosquito population affecting recreational and residential areas along the Santa Ana River in the City of Eastvale. The spray application will be conducted between the hours of 3:00 am to 6:00 am at the following locations: the Riverwalk bike trail located next to the Santa Ana River, and Granja Vista Wetlands. Please see attached images for 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 elevated abundance of adult mosquitoes, 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 April 22nd., 2021 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.
