SOUTH CAROLINA — As temperatures climb and outdoor activities ramp up, South Carolina health officials are urging residents to take extra precautions against mosquitoes — and the diseases they can spread — as peak season begins.

The South Carolina Department of Public Health (DPH) says the state is home to at least 61 mosquito species, some of which can transmit viruses including West Nile, eastern equine encephalitis, La Crosse encephalitis, and Saint Louis encephalitis, as well as heartworm in pets. West Nile remains the most common threat to humans.

“As we head into the summer months, the risk of mosquito‑borne illnesses should not be overlooked,” said Dr. Chris Evans, DPH State Public Health Entomologist. “When we each take small actions to eliminate breeding areas and prevent bites, we strengthen our defense against mosquito‑borne illnesses and contribute to a safer, healthier summer for everyone in South Carolina.”

Mosquitoes can breed in as little as five days

DPH warns that mosquitoes can develop in any standing water lasting more than five days, making yards, patios, and outdoor living spaces prime breeding grounds if not maintained.

To help residents reduce mosquito populations, the agency recommends following the “7 Ts”: TIP, TOSS, TURN, TIGHTEN, TAKE CARE, TREAT, and TEAM UP — all focused on eliminating standing water and maintaining outdoor spaces.

Officials recommend EPA‑approved repellents

For those spending time outdoors — especially at dawn or dusk — DPH recommends using EPA‑approved mosquito repellents containing DEET, picaridin, IR3535, or oil of lemon eucalyptus. Light‑colored, tightly woven clothing and long sleeves are also encouraged.

DPH expands mosquito surveillance tools

DPH partners with the CDC to monitor mosquito populations statewide, trapping and testing insects for viruses and tracking disease activity in birds, domestic animals, and humans.

The agency recently launched a mosquito‑borne disease dashboard, offering real‑time data on West Nile, malaria, and dengue cases among South Carolina residents. A companion mosquito‑borne disease viewer tracks infections detected in birds, mosquitoes, and certain animals.

Residents can also assist by submitting certain species of dead birds for testing through DPH’s annual surveillance program, which runs from mid‑March through November.
