High river levels inside the levees along the Feather River have produced an abundance of aggressive, daytime biting mosquitoes. As their numbers have crossed an actionable threshold, an aerial mosquito control application has been scheduled for this area on the evening of Wednesday, April 3, 2019. Spraying will be performed starting at or around 6:00 PM and lasting up to 1.5 hours. Treatment is dependent on appropriate weather conditions. Aircraft applications will be made with a white, twin engine Cessna 232 Skymaster or a yellow and blue stripe Air Tractor flying at approximately 300 feet in elevation. The District’s contractor will be applying naled, a material registered by the Environmental Protection Agency and applied according to label directions by the District’s trained and certified contractor. Although this material poses a low risk to human health, some people may prefer to avoid or minimize exposure by remaining out of the area when spraying is taking place. 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.
