City of Columbia to spray for adult mosquitoes through the remainder of the season

June 3, 2024

In an effort to control the mosquito population and reduce the risk of mosquito-borne illness, the City of Columbia will be spraying for adult mosquitoes through the remainder of the season, as recommended. Spraying is usually conducted between midnight and dawn; however, it is possible for spraying to be conducted earlier depending on conditions. Residents allergic to the products permethrin, deltamethrin, or tau-fluvalinate should notify Vector Control staff by calling 803-545-4229 or emailing [email protected]. All beekeepers should call or email Code Enforcement to notify staff of their hives.

Residents are urged to take these preventive measures to reduce the threat of mosquitoes:

  • Use, according to the label instructions, EPA registered insect repellents that contain DEET, Picaridin, IR3535 or oil of lemon eucalyptus
  • Clear drainage ditches of debris and weeds
  • Empty and turn over outdoor containers holding water
  • Eliminate overgrown grass, weeds, and shrubbery
  • Pack tree holes with sand
  • Clean clogged roof gutters
  • Keep boats overturned, drained or covered (covers should not collect water)
  • Stock ornamental ponds and water gardens with top-feeding minnows
  • Properly maintain swimming pools
  • Change the water in pet dishes, birdbaths and plant containers at least once a week
  • Make sure there are screens on rain barrels and use the water as soon as possible.
