Davis avoids aerial spraying for mosquitoes – for now

The city of Davis has been spared aerial spraying for mosquito control – at least temporarily – after laboratory testing results Thursday showed a decline in the mosquito population and the West Nile virus infection rate, officials said.

Luz Maria Robles, spokeswoman for the Sacramento-Yolo Mosquito and Vector Control District, said monitoring activities will continue, along with ground spraying around parks and neighborhoods where West Nile virus has been detected.

The district had announced Wednesday that aerial spraying in Davis was contemplated due to a significant increase in the mosquito population and the number of mosquitoes infected with West Nile virus.

The Yolo County Public Health Department last week confirmed two human cases of West Nile virus. As of Thursday, the district reported that 143 mosquito samples and 43 dead birds in Yolo County have tested positive for West Nile virus this year.

In Sacramento County, one human case of West Nile virus has been confirmed and six others are under investigation, officials said. In addition, 319 mosquito samples and 337 dead birds have tested positive for the virus so far this year.

For current information about any treatment planned, see the district’s website, www.FIGHTtheBITE.net. Residents can subscribe to receive email notifications for mosquito treatment by ZIP code by going to “Spray Notifications” on the website.
