At least 61 different species of mosquitoes exist in South Carolina. The two-winged insects — whose name means "little
fly" — are closely related to flies like gnats and no-see-ums.
Mosquitoes are a pest that can cause itchy bites, but they can also cause more serious health issues like spreading diseases.
The most common diseases that could potentially be carried by mosquitoes in South Carolina include: West Nile,
Eastern Equine Encephalitis,
La Crosse encephalitis, Saint Louis encephalitis virus, and dog/cat heartworm.
DHEC works in partnership with the U.S. Centers for Disease Control and Prevention to monitor mosquito populations for diseases
that can be spread to humans. The agency also provides information to help individuals and communities take action to reduce
mosquito populations in their area and prevent bites.
Mosquito control programs are managed at the local community level. Click here to find a listing of local mosquito control programs. In
light of the 2015 flood, DHEC has been urging local governments to review, update or create local ordinances designed to
help their mosquito control programs reduce or treat standing water that can provide breeding sites for mosquitoes.
Protect Yourself from Mosquito Bites

Keep mosquitoes outside: Use air conditioning or make sure that you repair and use window/door screens.
