"Ticks and mosquitoes are common across North Carolina, but the diseases they spread can be serious. As the weather warms up and North Carolinians enjoy the outdoors more frequently, we encourage everyone to stay safe by wearing protective clothing, using EPA-approved repellents and always checking for ticks after spending time outside.”
-Emily Herring, NCDHHS Public Health Veterinarian
