Mosquito spraying comes to an end for 2014

All of the District's regular fogging, both by air and ground based fogging truck, has ended for the 2014 season. Mosquito abundance data shows a dramatic drop in mosquito numbers halting the spray program. Some limited spraying still could occur in response to a localized mosquito problem or detected disease activity.

Detected West Nile virus through 9/19/2014

  • Mosquito Control Matters

  • Is your swimming pool green?


    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, 2015. 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.
