If you just discovered a massive, dark snake stretched out in your garage or slithering through your attic in Mooresville, there is a very high probability you're looking at an Eastern Rat Snake. Commonly known as a Black Rat Snake, these impressive climbers are a frequent sight around local homes. While their sheer size can be incredibly intimidating, rest assured that they are completely non-venomous and generally docile. NC State Extension counts the eastern rat snake among the harmless snakes of North Carolina.
The Eastern Rat Snake is one of the most frequently encountered snakes in North Carolina homes. Because they can grow quite large (often reaching 5 to 6 feet in length), they frequently cause a lot of panic when discovered indoors.
Unlike copperheads, which stick to the ground, black rat snakes are exceptional climbers. Their bread-loaf body shape allows them to wedge between bricks, scale rough siding, and climb trees with ease. If you have a snake in your attic, roof, or upper floors, it is almost certainly a rat snake.
They enter homes for one primary reason: Food. Rat snakes are nature's pest control. If one has taken up residence in your attic, crawlspace, or garage, it is highly likely that you have a rodent problem (mice, rats, or squirrels) or roosting birds that the snake is feeding on. They are simply following the food source inside.
No, black rat snakes are non-venomous and generally harmless to humans and pets. They do not possess venom glands. However, they are wild animals. If they are cornered, picked up, or stepped on, they will bite to defend themselves. While a rat snake bite isn't medically significant (it won't poison you), it can be painful and runs the risk of bacterial infection.
A common defensive behavior of the rat snake is to rapidly shake its tail against dry leaves or flooring, mimicking the sound of a rattlesnake. This is a bluff meant to scare predators away.
Even though they are beneficial for rodent control, nobody wants a 6-foot snake living inside their walls or attic. Our professional snake removal service in Mooresville handles these situations safely and humanely.
This is probably the most common question we get when someone spots a large black snake. The honest answer? It really depends on exactly where the snake has decided to hang out.
If you see a black rat snake out in your yard, garden, or woodline, the absolute best thing you can do is let it be. These snakes are essentially free, full-time pest control. They actively hunt the mice, rats, and voles that would otherwise tear up your landscaping or try to get into your house. A lot of homeowners who decide to just coexist with them notice a huge drop in their outdoor rodent problems.
Sheds and detached garages are a bit of a gray area. Some folks don't mind a snake living in the shed if it keeps the mice out of the lawnmower wiring. But we totally understand if you don't want to step over a six-foot snake to get your rake.
However, when it comes to the inside of your house, attic, or walls, that's where we draw a hard line. Even though they are completely harmless to humans, having a massive snake living in your attic is incredibly stressful. It's not something you should have to just "put up with." That's when professional removal, followed by sealing up how they got in, is the right move.
One of the saddest reasons harmless rat snakes are killed here in North Carolina is simply because people think they're copperheads. It's an easy mistake to make if you don't know what to look for, because young rat snakes look absolutely nothing like the solid black adults.
Baby rat snakes hatch out with a gray body covered in dark brown, irregular blotches. If you glance quickly, that pattern can definitely give you a "copperhead scare." The markings are blotches, though, not the hourglass bands of a copperhead.
Head shape will not settle it. NC State Extension notes that some harmless snakes flatten their heads and flare their jaws, so judge the pattern from a distance instead. By the time a rat snake hits about three feet long, all those baby patterns fade away and it turns solid black.
Other small snakes get mistaken for copperheads too. Our guide on how to identify a baby copperhead compares the common look-alikes.
Finding a rat snake inside your house is rarely just about the snake. It's usually the first big warning sign of a much larger issue: you probably have rodents. Rat snakes don't just wander into attics for the view; they go where the food is.
If we pull a rat snake out of your home, we're immediately going to start looking for the real culprits. Often, homeowners tell us they've been hearing scratching or scurrying sounds in the walls or ceiling right above the bed, especially at night. That's not the snake. That's the mice the snake was hunting.
We also look for small, dark droppings along baseboards or up in the attic insulation, gnaw marks on wiring or wood framing, and little nests made of shredded paper or fiberglass. Sometimes there's even a faint, musty smell in enclosed spaces. When we find these signs, we don't just hand you the snake and leave. We'll talk to you about rodent control and how a solid exclusion and sealing plan can stop both the mice and the snakes from coming back.
It's extremely unlikely. Rat snakes are non-venomous and generally try to flee from larger animals. A large rat snake could bite in self-defense if a curious dog corners it, but the bite would be superficial, similar to a scratch. The main concern is the stress and panic the encounter causes for both the pet and the owner.
Rat snakes are among the best climbers in the snake world. They can scale brick walls, climb trees, and squeeze through gaps as small as a quarter. Common attic entry points include gaps where the soffit meets the roofline, torn gable or attic vents, unscreened plumbing stacks, and gaps around HVAC lines entering the attic.
If the conditions that attracted the first snake remain (rodents, open entry points), yes, another snake could eventually find its way in. That's why we always recommend addressing the root cause rather than just removing the symptom. A thorough property inspection and exclusion service is the most effective long-term solution.
