Kentucky officials said they will begin spraying for mosquitoes after a bird in the area tested positive for West Nile Virus.

The Lexington-Fayette County Health Department said the spraying will happen in the 40505 and 40511 area codes, near where the bird was found. Spraying will occur from 3 – 6 a.m. on Tuesday, Sept. 14.

The mosquito spray used by the health department only affects adult mosquitoes that are in the air at the time of spraying.
