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.
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.

“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.
