 NMVCD Treatment for Adult Mosquitoes


The Northwest Mosquito & Vector Control District will perform adult mosquito spray treatments on June 7th, 2019 to lower the mosquito population affecting recreational and residential areas along the Santa Ana River in the City of Eastvale, and the City of Norco. The spray application will be conducted between the hours of 2:00 a.m. to 6:00 a.m. at the following locations: the Riverwalk Park and bike trail located next to the Santa Ana River, Eastvale Community Park, Granja Vista Wetlands, and Silverlakes Sports Complex. 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 trap counts, 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 are being posted on June 5th, 2019 in the areas that will be sprayed to inform 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 the District at 951-340-9792.
