Identifying Black Rat Snakes

Black rat snakes are a species of non-venomous snakes that can be found in many parts of North America. They are often mistaken for other venomous species, such as the copperhead or rattlesnake, due to their similar coloration. However, there are several key physical characteristics that can help identify black rat snakes.

Physical Characteristics

Black rat snakes are typically black or dark brown in color with white or gray underbellies. They can grow to be quite large, with adults reaching lengths of up to six feet. One unique feature of the black rat snake is its keeled scales, which give it a rough texture.

Young black rat snakes have a distinct pattern of gray or brown blotches on their back which they lose as they mature. In addition, black rat snakes have round pupils and no heat-sensing pits on their faces, which are common features of venomous snakes.


Black rat snakes are generally docile and non-aggressive towards humans, but they can become defensive if they feel threatened. When frightened, they may emit a foul-smelling musk or coil up into a defensive posture. However, they are not known to bite unless provoked.

Black rat snakes are excellent climbers and are often found in trees or on fence posts. They are also excellent swimmers and can be found near bodies of water such as ponds or streams.

Identification Tips

When trying to identify a black rat snake, it’s important to consider its physical characteristics and behavior. Look for the keeled scales, lack of heat-sensing pits, and round pupils. If you spot a large, black or dark brown snake with a white or gray underbelly, it may very well be a black rat snake. If in doubt, it’s best to seek the advice of a professional.

Venomous or Non-Venomous?

One of the most common misconceptions about black rat snakes is that they are venomous. However, this is not the case. These snakes are non-venomous, which means their bite is not poisonous to humans. They are not considered dangerous, and their bite is not fatal.

Black rat snakes do have saliva, which contains enzymes that help digest their prey. These enzymes can cause mild irritation or inflammation when in contact with human skin, but it is not harmful or life-threatening. In fact, black rat snakes are considered beneficial to humans, as they help control rodent populations and are harmless to humans.

It is important to note that while black rat snakes are not venomous, other species of snakes can be. It is always important to exercise caution and respect when encountering any snake in the wild, and to avoid handling or approaching them, especially if you are not familiar with snake identification and safety.

Black Rat Snake Behavior

Black rat snakes are typically solitary creatures that prefer wooded areas, fields, and farmlands where they can hunt for small prey. They are active during the day and can often be found basking in sunny areas or climbing trees.

When threatened, black rat snakes will try to flee, but if cornered, they may also hiss, shake their tail, and even strike, although they are not venomous. However, they should still be treated with caution as a bite can result in injury and infection.

One interesting behavior of black rat snakes is their habit of eating other snakes, including venomous species such as copperheads. This is an important ecological role as it helps control the population of venomous snakes in the area.

Overall, it is essential to respect the natural behaviors and habitats of black rat snakes to avoid negative interactions and promote coexistence.

Black Rat Snake Bites

Despite their non-venomous nature, black rat snake bites can still be painful and may cause swelling or irritation. If you are bitten by a black rat snake, it is important to stay calm and seek prompt medical attention. In rare cases, individuals may experience an allergic reaction or other complications.

To minimize the risk of a black rat snake bite, avoid handling or provoking the snake in any way. If you encounter a black rat snake in the wild, give it plenty of space and observe it from a distance.

Should a black rat snake does bite you, clean the wound with soap and water and apply a sterile bandage. If you experience any signs of an allergic reaction, including difficulty breathing or swelling in the face, seek immediate medical attention.
