Post Date:10/21/2020 2:26 PM

Northwest Mosquito & Vector Control District will perform adult mosquito spray treatments on October 30th, 2020 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 2:00 am to 6:00 am at the following locations: the Riverwalk Park and bike trail located next to the Santa Ana River, Eastvale Community Park, and Granja Vista Wetlands.
