Health department crews are spraying for mosquitoes in parts of East and South Knoxville Thursday night.
Crews are spraying along North Cherry Street and Magnolia Avenue in East Knoxville, and spraying a few neighborhoods near Chapman Highway a second time.
The Health Department says it's trying to stop the spread of West Nile Virus. They have only found the virus in mosquitoes so far. There have been no human cases.
Health officials ask you stay indoors while spraying.
