Adult Mosquito Treatment Planned for June 25th, 2021

The District will perform adult mosquito spray treatments on June 25th.,

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, Eastvale Community Park, and

Granja Vista Wetlands, located next to the Santa Ana River. 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 June 23rd., 2021 in the areas affected by our spray application.

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.
