Fire ants have spread northward from their original range in the Deep South and now pose a real concern for residents and visitors across North Carolina.
Are they in North Carolina?
Yes, imported fire ants are established throughout North Carolina. These invasive insects from South America have expanded their range northward over the past several decades and now live in all regions of the state, from the coastal plains through the piedmont to the foothills. Fire ants thrive in North Carolina's warm months and survive winter in protected nests and warmer microclimates. The state's humid subtropical climate in the coastal and southern regions is particularly favorable for fire ant colonies. Populations are densest in the southern portions of the state, including areas around Charlotte, Greensboro, and along the coast. Northern parts of North Carolina experience harder freezes that limit fire ant populations, but established colonies persist even in the state's northern regions. If you live or work in North Carolina, learning to recognize fire ants and following prevention strategies is important. Visit ourFire Ant guide for North Carolinafor detailed information.

How dangerous is it?
Fire ant stings are painful and medically significant for many people. The sting injects venom that causes immediate burning pain, described as feeling like a match head being held against the skin. Within 24 hours, a small raised bump or pustule develops at each sting site. For most healthy adults, fire ant stings cause local pain and itching that resolves within a few hours. However, the sting can be more serious for people with allergies to insect venom. Severe allergic reactions, though uncommon, can include facial swelling, throat tightness, difficulty breathing, or anaphylaxis. Blisters may form if you scratch the sting, increasing risk of infection. Children and elderly people sometimes experience more severe reactions than healthy adults. Death from fire ant stings is extremely rare in the United States, even in regions with high populations. With prompt medical care, even severe allergic reactions are treatable. For people without allergies, fire ant stings are painful but not medically dangerous. This is general information, not medical advice; if you are stung, call Poison Control at 1-800-222-1222, or 911 if symptoms are severe.
How to recognize one
Fire ants are small insects, typically one-eighth to one-quarter inch long. They range in color from reddish-brown to dark red, with abdomens darker than the rest of the body. Each fire ant has a two-part waist structure, though this requires close inspection to see clearly. Fire ant colonies are recognizable by their distinctive mounds built in soil, which typically stand from a few inches to over a foot tall. These mounds have a hard-packed, dome-shaped appearance and are harder and more compact than mounds built by other ant species. Fire ants are highly aggressive when their nest is disturbed and will swarm onto anything they perceive as a threat. A single fire ant is small and not particularly intimidating, but the organized mass attack of a colony makes fire ants distinctive. They do not fly but move rapidly on the ground. If you watch an ant mound and see hundreds of ants boiling out when disturbed, you are likely looking at a fire ant nest. Other North Carolina ant species, such as carpenter ants and native species, do not exhibit this aggressive swarming behavior. Learning this identification is valuable for preventing encounters on trails and in yards.
What to do if you are stung
If fire ants attack you, the immediate priority is to leave the nest as quickly as possible. Brush ants off your skin with your hands or a stick to remove them, then move to a safe distance away from the mound. Do not panic or jump around, as sudden movement can trigger more ants to attack. Remove any tight clothing like socks or waistbands that may trap ants. Wash the affected area with soap and water immediately. Do not scratch the sting, even though it will itch intensely, as scratching can lead to infection. Most fire ant stings require no medical treatment. A cool compress applied to the area can reduce discomfort. Over-the-counter antihistamines or hydrocortisone cream may help with itching. If you develop signs of infection, such as increased warmth, redness, or pus, contact a doctor or pharmacist for guidance. For people with severe allergies to insect stings, any signs of facial swelling, throat tightness, or difficulty breathing require immediate emergency care. This is general information, not medical advice; if you are stung, call Poison Control at 1-800-222-1222, or 911 if symptoms are severe. Do not attempt home treatments like cutting, sucking, or applying ice without professional guidance.
How to prevent encounters
Since fire ants live throughout North Carolina, taking precautions when outdoors is wise. Wear closed-toe shoes and long pants tucked into your socks when hiking, camping, or working in grass and natural areas. Inspect your clothing and check for ants before entering your home or vehicle. Be cautious when sitting on the ground; use a blanket or chair instead. Before sitting on logs, firewood piles, or outdoor furniture, look for ant mounds and signs of ant activity. Never intentionally disturb an ant mound, and teach children that ant mounds should never be disturbed. When camping or picnicking, place your tent and seating away from moist areas and vegetation where fire ants often build colonies. Store food in sealed containers. If you are working in a yard or garden, wear protective footwear and check regularly for new mounds. Remove fire ant mounds from your property by contacting a professional pest control service or following guidance from the North Carolina Cooperative Extension. Check ourwildlife guidesfor additional information about outdoor safety. After spending time outdoors, check your feet and legs for ants or bites before entering your home.
Where in North Carolina and when
Fire ants are established throughout North Carolina from the coast to the mountains. They are most numerous in the southern and coastal regions, particularly around Wilmington, Fayetteville, and other areas in the Coastal Plain. The Piedmont region, including areas around Charlotte and Greensboro, also has significant fire ant populations. Even in the mountains and the northern parts of the state, fire ants establish colonies, though populations may be smaller and less visible during harsh winters. Fire ants are active and visible during warm months from late spring through early fall. Peak activity occurs in summer, June through August, when temperatures are warmest. In winter, fire ants retreat deep into their nests and are rarely seen, but the colonies survive in the protected soil. After a mild winter, populations can expand rapidly in spring. Spring rains create ideal conditions for fire ants to spread and build new mounds. If you see a mound in North Carolina, it could be active at any time from April through November. Understanding seasonal timing helps you know when to be most cautious. Learn more about fire ants on ourNorth Carolina wildlife page.
Harmless lookalikes
If you see small reddish ants in North Carolina, they are far more likely to be harmless native species than fire ants. The state is home to several native ants that can be confused with fire ants at a glance. Pharaoh ants are tiny, pale yellow or tan ants common in buildings and around moisture. They are much smaller than fire ants and lack aggressive behavior. Pavement ants are dark brown or black and frequently seen marching along sidewalks, driveways, and building foundations. They do not sting. Carpenter ants are much larger, entirely black, and known for damaging wood in homes. They do not swarm aggressively like fire ants. Native red ants found in gardens and open areas do not sting and do not build the hard dome mounds characteristic of fire ants. Acrobat ants are small and may be confused with fire ants but do not exhibit the aggressive mound-defending behavior. Most ants you encounter in a North Carolina yard or field are native species without a sting. If you observe hundreds of ants pouring out of a mound when disturbed, you have likely found a fire ant nest. Visit ourfire ant guidefor detailed comparison images and descriptions.
Frequently Asked Questions
