 Adult Mosquito Treatment Planned for June 24th

The District will perform adult mosquito spray treatments on June 24th.,

2022 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: Granja Vista Wetlands, Eastvale Community Park, and the

Santa Ana River bike trail. Please see attached images for exact spray


The District will be treating this area 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 this

area, and the majority of our efforts focus on preventing mosquito breeding

and killing mosquito larvae before they become flying adults; However, after

surveying the mosquito populations present within these areas, we have

decided that adult mosquito control via truck mounted ground fogger is our

best means to control the current populations detected. Signs were posted on

June 22nd., 2022 within our treatment areas, and 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.
