West Nile aerial spraying starts tonight in areas south of downtown Sacramento

Areas south of downtown Sacramento will undergo an aerial mosquito spray treatment on Monday and Tuesday after numerous bird and mosquito samples in the area tested positive for West Nile Virus.

The sprays will be conducted by the Sacramento-Yolo Mosquito and Vector Control District, which monitors mosquito conditions throughout the year.

The spraying will last from 8 p.m. to midnight and cover nearly 17,000 acres from Broadway on the north down to Meadowview Road on the south and from Interstate 5 on the west to Power Inn Road on the east.

The spray treatment will be done with Trumpet, an insecticide registered for use in mosquito control by the U.S. and California Environmental Protection Agencies. According to the district website, the sprayings do not pose a risk to human or pet health, but residents should close doors and windows and remain inside as much as possible during the aerial treatment. The mosquito-killing particles break down quickly in sunlight and will not build up over time or seep into

In recent weeks, the district has seen increasing levels of West Nile Virus infection among birds and mosquitoes in the area, spurring concern about the possibility of human infection.

“With the 4th of July holiday, we know many residents will be spending time outdoors and enjoying the fireworks at dusk, a time when mosquitoes will be actively biting,” said District Manager Gary Goodman. “It’s critical that we act now to reduce the number of infected mosquitoes and decrease the risk of human transmission.”

Public information officer Luz Maria Rodriguez said District scientists are not sure why southern Sacramento neighborhoods have become a hotspot for West Nile Virus activity this year. Last year, Rodriguez said, the district did not need to conduct any urban aerial sprays.
