The Sutter-Yuba Mosquito & Vector Control District reports that in an effort to minimize the spread of WNV in the Sutter-Yuba area, District personnel will begin ultra low volume spraying in the Wheatland, Plumas Lake, Olivehurst, Linda, Marysville, south Yuba City, Live Oak, Sutter, Tierra Buena, Meridian and Robbins areas. Spraying will usually take place on Thursday evenings, with Meridian and Robbins being sprayed on Wednesday evenings. The first application of the season is scheduled to take place on Thursday, July 2nd. All pesticide applications are predicated on mosquito abundance, disease activity and favorable weather conditions. Spraying will be performed with pickup mounted foggers every week starting at about sunset and continuing up to 2 ½ hours.
Agricultural areas are being treated for adult mosquitoes weekly with ground fogging on Tuesday and Wednesday evenings. Agricultural areas west of Yuba City, east of Olivehurst/Plumas Lake and north of Marysville may be treated during the evenings by aircraft as necessary. Spraying will be performed weekly starting at sunset and lasting 2 to 3 hours and are dependent on appropriate weather conditions. Aircraft applications will be made with a yellow and blue striped Air Tractor, a white Cessna 232 Skymaster or a white, with red stripe Ag Wagon 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.
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.
