Dorchester County is set to begin its annual Mosquito Control Program with ground spraying efforts starting April 14, 2026. The county is taking proactive measures to protect its residents from the spread of mosquito-borne diseases by initiating pesticide spraying operations, administering larvicide in wet areas, and educating the public on prevention methods.
Ground spraying will occur between the hours of 9 p.m. and 5 a.m., Monday through Friday, excluding holidays. The county encourages residents to familiarize themselves with their local spraying zones by visiting Dorchester County's spray zones website. A bi-weekly spray schedule is available to assist residents in staying informed about spraying operations in their area, accessible at Dorchester County's spray schedule website. Additionally, residents can request ground spraying via an online form available at Dorchester County's request spraying website.
Mosquitoes not only cause discomfort through itchy bites but are also vectors for several serious diseases. In South Carolina, common mosquito-borne diseases include West Nile, Eastern Equine Encephalitis, La Crosse Encephalitis, Saint Louis Encephalitis, Zika, and dog/cat heartworms. The Mosquito Control Program is essential in mitigating the risk of these diseases and maintaining public health.
Residents are encouraged to participate in reducing mosquito breeding sites by eliminating standing water from their properties and maintaining clean gutters and pools.
