An aerial mosquito control application has been scheduled for agricultural areas west of Yuba City on the evening of Monday, June 27, 2022. Spraying will be performed starting at sunset and lasting 2 to 3 hours. All treatments are dependent on appropriate weather conditions, and visibility due to smoke. Aircraft applications will be made with a white with red stripe, Ag Wagon, white, twin engine Cessna 232 Skymaster or a yellow and blue stripe Air Tractor flying at approximately 300 feet in elevation. The spray program will be discontinued in the fall when there is a significant drop in the mosquito population and disease activity. Over the mosquito season, the District will be using a combination of insecticides including Pyrethrins, Pyrethroids and Naled. These materials are registered by the Environmental Protection Agency and applied according to label directions by the District’s trained and certified technicians and contractors. Although these materials pose a low risk to human health, some people may prefer to avoid or minimize exposure by staying indoors, keeping their windows closed and turning off their window –mounted air conditioners, evaporative coolers and whole house fans when spraying is taking place in the immediate area. You can obtain additional information about spray operations by calling the District office at 674-5456 ext. 0 between the hours of 7 AM to 3:30 PM, Monday thru Friday. West Nile virus is transmitted to humans through the bite of an infected mosquito. Residents are strongly encouraged to limit outdoor activities during peak mosquito feeding times at dawn and dusk. When outside and mosquitoes are biting, wear long sleeves and long pants and apply a mosquito repellent. Keep mosquitoes outside of your home by making sure that door and window screens are in good repair.
