Adult Mosquito Treatment Planned for May 28th, 2021

Northwest Mosquito and Vector Control District will perform adult mosquito spray treatments on May 28th., 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 May 26th., 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.
