You can find rat snakes all over North Carolina. They like living up in the mountains and far down in the Coastal Plains. The rat snakes in the mountains look scary because they are almost entirely black, but they are very shy and will speed away from people rather than hang around if anyone comes near them. rat snakes that live down in the plains will have a more olive color that makes it easier for them to blend in with their surroundings. Fear not if you see a rat snake, they are non-venomous. In fact, rat snakes are very helpful to people because they primarily eat rodents and pests.

Ring-Necked Snake

It’s easy to recognize a ring-necked snake. They are usually brown or olive, sometimes they have an almost black base color but they will also have a red, orange, or yellow ring around their necks. Ring-necked snakes live all throughout the state of North Carolina. Their coloring changes depending on where in the state they are living, and ring -necked snakes that are coastal dwellers may not have a full ring around their necks. Homeowners and suburban dwellers may find ring-necked snakes living in their mulch, under flowerbeds or vegetable gardens, under planters, or under piles of leaves or grass clippings. The species is small, generally measuring just 10 to 15 inches, and is non-venomous.

Typically rainbow snakes have a black base color with three long narrow red stripes running down the entire length of the back. They may have yellow or cream bellies and some will also have yellow marking in addition to the red stripes. These snakes are semi-aquatic which means they like to be in or near water. They inhabit the southeastern Coastal Plains in North Carolina and live mostly in the swamps or near brackish rivers. They generally measure 3 to 5 feet in length when fully grown.

Carolina Swamp snakes don’t like people and don’t even like to be on the land that much! They are mostly aquatic and like to stay in shallow water that has a lot of vegetation where they can hide. You may see one of these stunning snakes when you are kayaking or boating in the shallows and swamps. The top of the snake is black or dark olive to make it easier for it to blend into vegetation, but the snake’s belly is a bright scarlet red. They are small and if they do leave the safety of their vegetative cover they only do it at night unless they are startled out of a hiding place. Like many snakes, the Carolina swamp snake is known by a number of names and also may be called the black swamp snake. They are generally are less than 2 feet long and can be very abundant in wetlands. Swamp snakes are only found in the Tidewater region along the coast.

Northern Water Snake

There are four different aquatic snakes (water snakes) that live in North Carolina, and one of them is the northern water snake. The northern water snake lives in ponds and in some of the streams throughout most of the state except in the Coastal Plains in the southern half of North Carolina. Northern Water snakes have a light tan or light brown body and have dark red, red orange, or dark brown markings. One thing that you should know is that Northern Water snakes can be aggressive. They are not venomous, so a bite from one of these snakes won’t seriously injure you. But they can give you a nasty surprise if you are not paying attention when you are fishing, boating, or kayaking in the ponds and rivers in North Carolina. The northern water snake is often confused with the cottonmouth (water moccasin). If you’re confused about the appearance differences between the two, make sure to read our full guide comparing water snakes and cottonmouths.

  • Copperhead
  • Cottonmouth

  • Timber rattlesnake

We’ll detail some of them below, starting with the most common venomous snake in North Carolina, the copperhead.

Copperhead snakes are the most common venomous snake in North Carolina. They are found in all parts of the state. 90% of venomous snake bites in North Carolina each year are from copperhead snakes. These snakes have color patterns that vary from light tan to gray and they have dark markings that run the length of their bodies that are in an hourglass pattern. They’re fairly short and usually fall somewhere between 2-4 feet long. But, they can camouflage themselves very well. While copperhead snakes lack a rattle, they will shake their tails as a warning. In addition, they will generally raise their heads as a warning before striking.

Cottonmouth Snake

The cottonmouth is another very common snake in some parts of North Carolina. It’s sometimes called the water moccasin, so locals may call it a water moccasin instead of a cottonmouth. This snake prefers the water and it’s main habitat in North Carolina is in the Coastal Plains and in the Outer Banks. You may see one of these snakes in the water or near the water. Cottonmouth snakes are mostly black, like many other snakes, but when they open their jaws wide they expose a large off-white mouth. That’s where the name “cottonmouth” comes from.

Timber Rattlesnake

In North Carolina, timber rattlesnakes live primarily high up in the mountains. But there are some living in the Coastal Plains and parts of Piedmont too. Timber Rattlesnakes are about four to five feet long and the snakes that live in the mountains have colors that help them blend into the local environment. They are gray, brown, and black with dark markings that help them conceal themselves in the foliage and trees.

Pygmy Rattlesnake

Pygmy rattlesnakes are small but also a scary sight! They are tiny compared to other rattlesnakes. They’re just about 12 to 24 inches long. In South Carolina, they are usually light gray with dark gray or black large patches on their backs. And even though they are venomous they will try to avoid any kind of confrontation. Pygmy’s prefer to rely on their coloring to camouflage them. However, don’t be fooled by their small size. They can and will bite when threatened or if you try to handle them. In North Carolina, pygmy rattlesnakes live close to metro areas, they can be found in Crowder’s Mountain State Park near Charlotte, for example, and in some counties in the Coastal Plains.
