By July 30, 2026No Comments

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.
