The County says mosquito control is the biggest part of its vector program. During summer it responds to mosquito complaints, and inspectors visit the site, locate the source and help residents take preventive action. It monitors mosquito activity in 22 of the most populated zones using light traps and rain gauges, sprays for adult mosquitoes at night in the areas its data shows are most in need, and works with the SC Department of Public Health to test mosquito samples and dead birds for disease. The County does not provide backyard spraying.

Its listed services are residential yard and property inspection for county citizens, ULV fogging treatment, and public education. Residents can request a mosquito survey of their property with the County's Mosquito Issue Request Form, and can report beehives, organic gardens or household members with respiratory sensitivities on a separate awareness form so Vector Control can factor them into planning. The County posts its fogging schedule by subdivision on its Vector Control page; the late-September and early-October 2026 runs were listed for 4 a.m. to 7 a.m.

The City of Columbia's own prevention list asks residents to clean clogged roof gutters, empty and turn over outdoor containers that hold water, and change the water in pet dishes, birdbaths and plant containers at least once a week. If mosquito pressure continues after that, an independent licensed pest-control company can propose recurring yard treatment. Columbia SC Pest Pros connects homeowners with independent professionals; see mosquito control information for questions to ask before hiring.
