Authorities Spraying Area Near Marshall Street And E. Black Street After Rock Hill Citizen Contracts West Nile Virus

ROCK HILL, S.C. (News Release) — South Carolina Department of Health and Environmental Control (SCDHEC) recently alerted York County Emergency Management about a confirmed case of West Nile virus in a Rock Hill citizen. Due to the confirmed human case, DHEC recommends increased education and control measures. To help prevent mosquito exposure, eliminate areas of standing water, use insect repellent, keep skin covered, and keep windows and doors closed. To control the current mosquito population in the area, DHEC also recommends spraying for mosquitoes within a 1-mile radius of Marshall Street and East Black Street.

From the roadway, the contractor will use a truck mounted sprayer in the 1-mile radius surrounding these streets starting about 10 PM Tuesday night September 15, and could take approximately 4-5 hours to complete. The contractor will use a product called Aqua-Reslin. While the material is not harmful to people, pets, other insects, and gardens, it’s not recommended to be directly in the path of the spray. Beekeepers within the 1-mile radius are advised to cover hives that night.
