Are they in North Carolina?
Yes, North Carolina has two rattlesnake species. Eastern diamondback rattlesnakes are found in the southeastern coastal plain and Sandhills regions, including areas around the Outer Banks, south eastern lowlands, and the Sandhills of south central North Carolina. They inhabit longleaf pine forests, pocosins, and sandy areas. Timber rattlesnakes live in the mountains, foothills, and western regions of North Carolina, particularly in the Blue Ridge and Smoky Mountains, and scattered through central and western counties. Timber rattlesnakes are rare in the coastal plain. Most encounters occur in spring through fall when temperatures are warm. The western mountains have higher concentrations of timber rattlesnakes than the coastal region. Learn more from ourRattlesnake in North Carolinaguide.
How dangerous is it?
A rattlesnake bite in North Carolina is medically serious and requires immediate care, but deaths are extremely rare with prompt treatment. Eastern diamondback bites produce hemotoxic venom that destroys tissue and causes severe swelling. Timber rattlesnake bites also produce hemotoxic venom with similar effects. About 85 percent of bites occur on the lower legs and feet when people step on or near a snake. Symptoms develop rapidly and include pain, swelling, discoloration, and potentially serious complications without treatment. Antivenom is highly effective when given soon after a bite. Healthy adults who receive prompt emergency room care rarely face life threatening complications. North Carolina averages around 50 to 80 snake bites per year, but only a small fraction are from rattlesnakes, and deaths are extremely rare.

How to recognize one
Eastern diamondback rattlesnakes are the largest rattlesnake in North Carolina, heavy bodied, and gray or tan with dark diamond shaped blotches. They have a rattle at the tail tip. Timber rattlesnakes are large, gray or tan with dark chevron or V shaped bands. Both have triangular heads and heat sensing pits along their jaw line. Eastern diamondbacks have light colored edges on their scales. Timber rattlesnakes in mountains may have a reddish or dark coloration. Both species have a distinctive rattle that produces a buzzing sound. Eastern diamondbacks hide in pine forests, scrub, and sandy areas. Timber rattlesnakes hide in rocky forested areas, under logs, in leaf litter, and in rocky ledges on mountain slopes. You can also browseNorth Carolina wildlife.
What to do if you are bitten or stung
Stay calm and remain still. Remove any rings, bracelets, or tight clothing from the bitten hand or arm immediately, as swelling develops quickly. Keep the bitten area below heart level and avoid movement. Do not attempt to kill or capture the snake. Do not apply ice, tourniquets, or try to cut the wound or suck venom. Seek medical attention immediately by calling 911 or driving to the nearest emergency room. In remote areas, know the location of the nearest hospital. This is general information, not medical advice; if you are bitten, call Poison Control at 1-800-222-1222, or 911 if symptoms are severe. Antivenom and supportive medical care are most effective when given quickly. Time is critical for good outcomes. See all of ourwildlife guides.
How to prevent encounters
Wear closed toe boots and long pants when hiking or working in areas where rattlesnakes occur. Watch where you place your hands and feet, especially on rocky slopes and in pine forests. Shake out sleeping bags, clothing, and boots before use. Keep wood piles and debris away from your home. Clear brush and tall grass from around buildings and yards. Do not reach under logs or into rocky crevices. Listen for the rattle, which is your warning to back away. Make noise while hiking so snakes can move away before you reach them. Do not hike alone in remote areas. If you encounter a rattlesnake, back away slowly and give it plenty of space to retreat.
Where in North Carolina and when
Eastern diamondback rattlesnakes in North Carolina are limited to the southeastern coastal plain and Sandhills, including parts of the Outer Banks, southeastern lowlands, and south central counties around the Sandhills region. They prefer longleaf pine forests and pocosins. Timber rattlesnakes live in the mountains, foothills, and western regions, including the Blue Ridge Mountains, Smoky Mountains, and scattered through central North Carolina to the fall line. Seasonally, both species are most active from April through October when temperatures are warm. In winter, they retreat to dens and become dormant. Spring and early summer see the most snake activity. ForNorth Carolina wildlifeinformation, explore our comprehensive guides.
Harmless lookalikes
Bullsnakes, gopher snakes, water snakes, and pine snakes are sometimes mistaken for rattlesnakes in North Carolina. These large, powerful snakes lack a rattle and are completely harmless. When threatened, some flatten their bodies, hiss, and strike, mimicking a rattlesnake and startling people. Racer snakes, kingsnakes, and other harmless species also occur in North Carolina. Pine snakes are large and often feared but are completely beneficial. Most North Carolina snakes are beneficial predators of rodents and insects. The good news is that your first encounter with a snake is far more likely to be a harmless species. Learning the differences helps reduce unnecessary alarm and fear.
