West Nile spraying will continue Thursday

By From page A1 | August 07, 2014

West Nile virus has claimed the lives of a 74-year-old Sacramento County woman and a Shasta County resident, health officials report. Aerial spraying to combat the virus will continue Thursday night over the cities of Davis and Woodland.

The Sacramento-Yolo Mosquito & Vector Control District uses a low-toxicity insecticide to kill mosquitoes that carry the virus. Spraying is planned between 8 p.m. and midnight, around the time mosquitoes are most active.

“Once we know the adults are infected and flying, aerial spraying is the only way to reduce them significantly and quickly,” said Luz Rodriguez, the district’s spokeswoman.

The insecticide Trumpet will be dispersed at ultra-low volumes over the cities. It poses minimal risk to humans and the environment, and people do not need to stay inside or close their windows, Rodriguez said.

Aerial spraying will take place over two areas. The Davis block is approximately 20,000 acres bounded by County Road 29 on the north down to Levee road on the south, and from County Road 98 on the west to County Road 105 on the east.

The Woodland block is about 12,000 acres from Churchill Downs Avenue on the north to County Road 25A on the south and from County Road 97 on the west to County Road 102 on the east.

The district has treated hot spots in and around Davis and Woodland with ground applications, she said, but a steady increase in the number of infected mosquitoes prompted more serious measures.

“Every season is different; this just seems to be a very intense year statewide,” Rodriguez said.

No human cases of West Nile virus have been reported in Yolo County. A total of 132 mosquito samples, 30 dead birds and one sentinel chicken have tested positive for West Nile in Yolo County to date.
