SHELBY COUNTY , TN – The Shelby County Health Department’s Mosquito Control Program routinely traps and tests mosquitoes for the presence of West Nile Virus ( WNV ) as a part of a comprehensive program to limit the spread of the virus through Shelby County .  
   Mosquito Control activities begin in February each year , with the application of larvicides to ditches and standing bodies of water in order to kill mosquito larvae and decrease the adult mosquito population . These treatments are a very effective way of reducing mosquito populations . Please view our
   ArcGIS story map
    that details our mosquito control prevention work throughout the year .
   Additionally , Mosquito Control conducts truck - mounted spraying to control the spread of adult mosquitoes that carry West Nile virus . No mosquitoes positive for West Nile Virus have yet been detected , but in order to proactively control mosquito populations , Mosquito Control will spray in zip codes where West Nile Virus was first detected in mosquitoes in 2022 .
