Upcoming Control Treatment for Adult Mosquitoes 

Northwest Mosquito and Vector Control District will perform adult mosquito spray treatments on Monday, July 20, 2026, to reduce mosquito populations in designated recreational areas within the City of Corona. The treatment is being conducted in response to elevated adult mosquito abundance in these areas.  

The spray application will be conducted between the hours of 3:00 a.m. to 6:00 a.m. at the following locations:  

  • Village Park, 860 Village Loop Dr., Corona, CA 92879  
  • Fairview Park, 1604 Fairview Dr., Corona, CA 92880 

These areas will be treated with Aqua-Reslin, a U.S. Environmental Protection Agency-registered insecticide (EPA Reg. No. 432-796), using truck-mounted Ultra-Low Volume (ULV) sprayers to control adult mosquitoes.  

Please see maps below for details on treatment areas.
