Aerial spraying for mosquitoes is scheduled Wednesday and Thursday nights in the Arden Arcade and Carmichael areas, a step prompted by the increasing number of birds and mosquito samples that have tested positive for West Nile virus, authorities said.
The Sacramento-Yolo Mosquito and Vector Control District announced the planned aerial treatment Tuesday. The district confirmed that 11 new mosquito samples and nine dead birds have tested positive for the mosquito-borne virus.
The area targeted for aerial treatment covers approximately 15,000 acres north of the American River. The treatment will be made using Trumpet EC, an insecticide registered by the U.S. Environmental Protection Agency and the California EPA for use in mosquito control and routinely used through the United Sates to control mosquitoes, according to a district news release.
The aerial spraying is scheduled from approximately 8 p.m. to midnight each night. Officials said the spraying may be postponed, modified or canceled if conditions are unfavorable.

“Over the past few weeks this has been an area of concern because many birds and mosquito samples have tested positive,” Gary Goodman, district manager, said in a written statement. “We need to take immediate action to reduce the risk of human infection.”
So far this year, 47 mosquito samples and 74 dead birds have tested positive for West Nile virus in Sacramento County, and one dead bird has tested positive in Yolo County, the district reported.
