Officials Urge Public to Stay Alert and Report Sightings
COLUMBIA, S.C. – South Carolina has confirmed its first sightings of the invasive spotted lanternfly (Lycorma delicatula), a destructive pest that threatens grapes, hops, stone fruits, and hardwood trees. Clemson University’s Department of Plant Industry (DPI) recently detected the insect in Greenville and Seneca.
Originally from Asia, the spotted lanternfly has now spread to more than 18 states, including neighboring North Carolina, Georgia, and Tennessee. While it poses no threat to people or pets, the insect could deal serious damage to South Carolina’s agriculture and forestry industries.
Why It Matters:
“This pest could have serious economic and ecological impacts,” said Steven Long of Clemson DPI. “Early detection is key. We’re asking the public to help us stop the spread.”
What to Look For:
-
Nymphs: Black with white spots, later turning red
-
Adults: About 1 inch long with gray wings and bright red underwings
-
Egg Masses: Appear like wet gray putty or dried mud on trees, bricks, cars, or equipment
-
Honeydew: Sticky residue that encourages mold and attracts other pests
The lanternfly spreads easily by laying eggs on vehicles and outdoor equipment, hitchhiking from one area to another. Officials encourage residents to inspect cars, trailers, firewood, and furniture, especially after traveling.

Coordinated Response
State and federal agencies are working together to contain the pest through surveys, treatment efforts, and public education. “We’ve fought other invasives before, and teamwork will be essential here too,” said Stephen Cole of Clemson Regulatory Services.
