Arkansas, known for its diverse wildlife and picturesque landscapes, is home to several species of venomous snakes. While encountering these reptiles can be a cause for concern, understanding their habits, habitats, and identifying features can help residents and visitors coexist safely with these fascinating creatures. In this article, we will explore the venomous snakes found in Arkansas and provide valuable information to promote awareness and safety.
1. Copperhead (Agkistrodon contortrix)

The Copperhead snake is one of the most commonly encountered venomous snakes in Arkansas. They are known for their distinctive copper-colored heads and hourglass-shaped patterns on their bodies.
Typically found in forested areas, these snakes are most active during warmer months. While Copperheads possess venom, their bites are rarely fatal to humans, but medical attention should always be sought.
2. Western Diamondback Rattlesnake (Crotalus atrox)

The Western Diamondback Rattlesnake, although more commonly associated with western regions, can also be found in the southwestern parts of Arkansas. Known for their characteristic diamond-shaped patterns and rattles on their tails, these venomous snakes prefer dry and rocky habitats.
They have a venomous bite, which can be life-threatening if left untreated. Caution should be exercised when encountering these snakes, and professional snake handlers should be contacted for removal if found near residential areas.
3. Timber Rattlesnake (Crotalus horridus)

The Timber Rattlesnake is a venomous pit viper species that inhabits forests and rocky areas in Arkansas. These snakes can grow to impressive lengths and are known for their distinctive dark crossbands on a lighter background.
Timber Rattlesnakes possess potent venom and, if provoked, may exhibit defensive behavior by shaking their tails to produce a rattling sound. These snakes should be admired from a safe distance, and professional assistance should be sought for their removal if they pose a risk to humans or pets.
4. Cottonmouth/Water Moccasin (Agkistrodon piscivorus)

The Cottonmouth, often referred to as the Water Moccasin, is a venomous snake found in various aquatic habitats throughout Arkansas. These snakes are dark in coloration, with a thick body and a distinctive white mouth, which gives them their name.
While generally non-aggressive, Cottonmouths will defend themselves when threatened. Avoiding their territory and being cautious around bodies of water can reduce the likelihood of encounters.
Safety Precautions
To coexist safely with venomous snakes in Arkansas, it is crucial to follow some essential safety precautions:
Educate yourself
Familiarize yourself with the different venomous snake species in Arkansas, their habitats, and their behaviors.
Keep your distance
Never attempt to handle or provoke a venomous snake. Maintain a safe distance and allow them to move away on their own.
Wear appropriate footwear
When hiking or walking in snake-prone areas, wear sturdy boots or closed-toe shoes to reduce the risk of snakebites.
Clear your surroundings
Keep your yard tidy by removing potential snake-hiding spots, such as tall grass, piles of debris, and woodpiles.
Seek professional assistance
If you encounter a venomous snake in your vicinity, contact local authorities or professional snake removal services for safe removal.
Interestingly, the safety precautions and awareness needed in Arkansas are not too dissimilar from those required in other states with venomous snakes, such as Colorado, where residents and visitors must also be vigilant and informed.
