Ongoing West Nile Virus Activity Prompts Aerial Spraying for Elk Grove, Pocket and Neighborhoods South of Fruitridge Rd.

July 20, 2018
–Spraying is scheduled for Monday and Tuesday next week
Elk Grove, Ca— The Sacramento-Yolo Mosquito and Vector Control District announced today that aerial spraying for mosquitoes that carry the potentially fatal West Nile virus is scheduled for two consecutive nights on Monday, July 23rd and Tuesday, July 24th from approximately 8:00 pm to midnight.  “After careful consideration and evaluation of surveillance results, we are moving forward with our plans for aerial spraying,” said Gary Goodman, District Manager.  Over the past few weeks the District has been closely monitoring the areas of Elk Grove, Pocket and neighborhoods south of Fruitridge Road due to many birds and mosquito samples testing positive for the virus.  Laboratory surveillance results obtained this morning confirmed that 23 more mosquito samples within the area of concern tested positive for the disease. “It is imperative that we act quickly to reduce the risk of human West Nile virus transmission and protect public health, especially since the hottest weeks of summer are upon us and populations of mosquitoes are very high increasing the risk to residents,” indicated Goodman. 
Approximately 41,000 acres will be treated, which covers Elk Grove, Pocket, and neighborhoods south of Fruitridge Road. Please refer to the map for more specific locations or visit  Aerial treatments will be made using Trumpet EC, an insecticide registered by the US Environmental Protection Agency (EPA) and California EPA for use in mosquito control and routinely used throughout the United States to control mosquitoes.  While attempts are made to notify the public, the District may postpone, modify or cancel a scheduled application due to unfavorable conditions.
