Recent releases from both Shasta and Oroville reservoirs have produced mosquitoes along the Sacramento River near Meridian and above Knights Landing in Sutter County and also along the Feather River near Nicolaus. Mosquito spraying by ground truck and/or specialized ground equipment will occur as needed until the problem has been abated. Spraying may occur any day of the week at either dawn or dusk and last up to 1 hour. Mosquito control pesticides are registered by the Environmental Protection Agency and applied to label directions by the District's trained and certified technicians and contractors. Although these materials pose a low risk to human health, some peolple in the immediate area may prefer to avoid or minimize exposure by staying indoors, keeping their windows closed and turning off window mounted air conditioners, evaporative coolers and whole house fans 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 through Friday.
