Public Service Announcement July, 14, 2014
Michael Kimball, Manager of the Sutter-Yuba Mosquito & Vector Control District, reports that West Nile virus activity is continuing to increase in Sutter and Yuba Counties. The District has detected WNV in mosquito collections from east Nicolaus, Rio Oso, Pleasant Grove, Pennington, Hallwood, east Marysville and south of Sutter so far in 2014. Additionally, dead birds collected in Yuba City, Tierra Buena, East Marysville, Olivehurst, Sutter and Robbins have tested positive for the virus. We have had no human or horse cases to date. While WNV activity is high, we are below the unprecedented levels of 2013 for the same time period. Kimball encourages residents to wear long sleeves and pants when outdoors during peak biting activity, which is typically at dusk and dawn. Use a repellent containing the active ingredient DEET, picaridin, oil of lemon eucalyptus or IR3535. These are the EPA approved mosquito repellents to prevent bites. Always follow package instructions for appropriate age and directions for use. Kimball stated that the District will remain diligent and aggressive in its fight against WNV. In an effort to minimize the spread of WNV in the Sutter-Yuba area, the District’s trained and certified technicians and contractors will continue ultra low volume ground fogging in urban and agricultural areas. East Marysville will be fogged on Monday and Thursday evenings until further notice due to high WNV activity. Aerial spraying in agricultural areas will start Tuesday July 15, 2014 and continue Mondays through Thursdays as needed. All insecticide applications are predicated on mosquito abundance, disease activity and favorable weather conditions. Spray schedules and information on insecticides that are being used can be found on the District’s website at www.sutter-yubamvcd.org or by calling the District office at 674-5456 ext. 0 between the hours of 7 AM to 3:30 PM, Monday thru Friday. 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 and evaporative coolers when spraying is taking place in the immediate area.
Detected West Nile virus through 7/18/2014
New area added to Town Routes for 2014
New for 2014, the District will be adding a portion of Yuba City to its regular town spray routes. Over the past couple of seasons, West Nile virus activity has been detected regularly within this area's borders. Reducing the number of mosquitoes in our town areas reduces the chances of a mosquito to human disease transmission. The District will be using the pyrethroid, Permethrin in town areas. Town spraying will commence weekly on Thursday nights at sunset, lasting no longer than 2 1/2 hours. Spraying will continue through the summer until mosquito numbers drop, typically in September. In 2013, 10 human cases of West Nile virus were diagnosed in Sutter County and 9 human cases in Yuba County.
This material is registered by the Environmental Protection Agency for this use and is applied according to label directions by the District’s trained and certified technicians. Although this material poses 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 and evaporative coolers 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.

The Sutter-Yuba Mosquito & Vector Control District reports that four mosquito collections and one bird in Sutter County have tested positive for West Nile virus. Additionally, two mosquito collections and one bird in Yuba County have tested positive for WNV. 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. The first application of the season is scheduled to take place on Thursday, July 3rd. 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 ˝ hours. Agricultural areas will be treated for adult mosquitoes with ground fogging on Tuesday and Wednesday evenings starting in mid-July. Agricultural areas west of Yuba City and north of Marysville may be treated Monday thru Thursday evenings by aircraft as warranted. 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 white Cessna Ag Wagon or white Cessna Skymaster 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. 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 and evaporative coolers 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.
Public Service Announcement Wednesday, June 18, 2014
The Sutter-Yuba Mosquito and Vector Control District has detected the first evidence of West Nile virus in Sutter and Yuba Counties in 2014. An American Crow recently collected in Tierra Buena tested positive for the virus. The District’s surveillance system is in full operation and mosquito control efforts are underway. Residents are asked to report dead birds to the California Department of Public Health website at www.westnile.ca.gov or by phone at 877-968-2473. It is very important to make sure to take the simple precautions that reduce the risk of mosquito bites and becoming infected with West Nile virus. The 4 “D”s is an easy way to remember how to prevent mosquito bites: D – DEET – use DEET, picaridin, oil of lemon eucalyptus or IR3535. These are the EPA approved mosquito repellents to prevent bites. Always follow package instructions for appropriate age and directions for use. D – Dawn and Dusk – avoid going outdoors at dawn and dusk when the mosquitoes that carry WNV are most active. Wear long sleeves and pants if you have to be outdoors when mosquitoes are present. D – Doors and windows – make sure that the screens on your doors and windows are not broken or torn. D – Drain all standing water around the outside of your house – buckets, jar lids, tires and flower pot trays are some common places. You can obtain additional information by contacting the District office at 674-5456 ext. 0 between the hours of 7 AM to 3:30 PM, Monday thru Friday.
Urban Source Eradication underway
The Sutter-Yuba Mosquito and Vector Control District has been pro-actively eliminating breeding sources of mosquitoes in urban areas. Urban sources are of particular concern as they produce mosquitoes that can transmit West Nile virus. Even a small source of standing water can breed thousands of mosquitoes over a summer. Mosquito Control Technicians have been going door to door in neighborhoods of Sutter and Yuba Counties requesting access to resident’s yards to look for and eliminate or treat these sources. Dressed in uniform, District employees will explain the purpose of their impromptu visit and ask for permission to inspect the yard. We are finding that through a quick visit, our technicians regularly discover breeding sources overlooked by residents. Technicians are only targeting mosquito breeding sources. They are not gathering information or reporting findings to other agencies. This public service is free and provides a direct benefit to the resident and their neighborhoods. The public health threat from West Nile virus has impacted Yuba/Sutter residents since 2003. This inspection is completely voluntary. Residents that are uncomfortable with this service can decline an inspection. In addition to the door to door program, the District also executes an aerial swimming pool surveillance program. The mosquito problems stemming from abandoned and unmaintained swimming pools are troublesome. Technicians with photo evidence of a neglected, green pool need to physically inspect these breeding sources. There is no penalty or charge to owners of problem pools. Inspection and treatment of a pool is quick and non-intrusive. Where photo evidence exists, an inspection is compulsory. Most residents are helpful and compliant, helping to reduce mosquito problems in their neighborhoods because of their cooperation. You can obtain additional information about our urban mosquito breeding elimination program by calling the District office at 674-5456 ext. 0 between the hours of 7 AM to 3:30 PM, Monday thru Friday.
Mosquito Control Matters
Is your swimming pool green?
WE'RE LOOKING FOR YOU!
The District is anticipating another busy year for neglected swimming pools in the Yuba-Sutter region. Algae-filled swimming pools and spas serve as breeding sites for disease transmitting mosquitoes. One dirty swimming pool is capable of breeding thousands of mosquitoes over the season. We will start using a Cessna TU206, fixed wing airplane starting on Monday, June 2nd to spot these green, un-maintained swimming pools in the communities of Live Oak, Sutter, Yuba City, Marysville, Olivehurst, Linda, Plumas Lake and Wheatland. The District identified 290 targets during aerial surveillance last season with 64 requiring treatment for mosquito breeding. The treatment of neglected swimming pools, spas and ornamental ponds will be free of charge to residents. Residents are encouraged to report mosquito breeding sites to the District. Proactive monitoring, early season mosquito control, and public education are critical to reducing disease transmission. Throughout the summer, basic proactive measures should be followed: DRAIN AND DUMP: Mosquitoes lay their eggs and grow in standing water. Empty water from buckets, old tires, flower pots and toys, and change water from pet bowls and bird baths every few days. DUSK AND DAWN: Mosquitoes bite in early morning and evening. Dress yourself in long sleeved shirts and pants. DEET: Use insect repellent with DEET in it. DEET keeps mosquitoes from biting you. Follow the directions carefully. The Sutter-Yuba Mosquito & Vector Control District is a public health agency dedicated to the control of mosquitoes and other vector-borne diseases. The District can be reached at 530-674-5456
Public Health Pesticide Application Notice
The Sutter-Yuba Mosquito and Vector Control District gives notice that it intends to continue to control immature and adult mosquitoes in the District as nescessary to protect the public's health. Applications may be made between January 1 and December 31, 2014. However, the majority of applications occur between May 1 and October 31. Application of pesticides is predicated on mosquito abundance as determined by the District's extensive surveillance system. Actual use varies annually depending on mosquito and vector-borne disease activity. Our District follows an Integrated Mosquito Management (IMM) program that is an ecosystem based strategy. It focuses on long term prevention of mosquitoes through a combination of techniques such as biological control, habitat manipulation and pesticides. Pesticides are used only after monitoring indicates they are needed according to established guidelines. Treatments are made with the goal of eradicating only mosquitoes. Pesticides are selected and applied in a manner that minimizes risk to human health, beneficial and non target organisms, and the environment. These materials are registered by the US Environmental Protection Agency and applied according to label directions by the District's trained and certified technicians. A comprehensive list of pesticides that may be used by the District this season can be viewed by clicking here.
Beginning April 1st, 2014, you can come by our office M-F 7AM to 3:30PM with a suitable container to pick up some fish for your mosquito breeding source. Mosquitofish are perfect for long term control in unmaintained swimming pools and spas, ornamental ponds, and nearby drainage ditches or ponds. You can come by our office M-F 7AM to 3:30PM with a suitable container to pick up some fish for free.
