Snakes in Louisiana: identification guide and where to start looking

1. What types of snakes live in Louisiana?

Louisiana hosts over 40 snake species, including both venomous and nonvenomous varieties. The most common nonvenomous snakes include rat snakes, garter snakes, and water snakes. Venomous species include the eastern cottonmouth, copperhead, timber rattlesnake, and coral snake. Most snakes you encounter are harmless and help control rodents.

2. Where in Louisiana are you most likely to see snakes?

You have the best odds near water sources: bayous, swamps, rivers, and lakes. Inland forests, pine savannas, and marsh edges also hold high numbers. Many snakes are spotted crossing roads at night, especially after spring rains. For a focused search, check the Atchafalaya Basin or the edges of the Kisatchie National Forest.

3. When is the best season for snake sightings in Louisiana?

Spring and fall offer the best conditions, with temperatures between 60 and 85 degrees Fahrenheit. Snakes are most active in the early morning and late afternoon. After a warm rain, they often bask on roads or trails. Summer heat drives them to seek shade, while winter brings inactivity except on unseasonably warm days.

4. How can you tell a venomous snake from a nonvenomous one?

Focus on head shape (triangular versus oval) and pupil shape (elliptical versus round) from a safe distance. Rattlesnakes have a rattle, cottonmouths show a white mouth lining, and coral snakes have red touching yellow bands. Many lookalike species, such as watersnakes versus cottonmouths, require careful attention to pattern and behavior. Water snakes often have thin necks and swim with their body submerged, while cottonmouths swim with their head raised.

5. What are the most commonly seen nonvenomous snakes in Louisiana?

The gray rat snake is widespread and often climbs trees or enters buildings. The common garter snake appears near water with a striped pattern. The Texas brown snake and rough green snake are also frequent. For identification, note pattern, scale texture, and body shape. The harmless watersnakes (like the banded watersnake) are often mistaken for cottonmouths.

6. Which venomous snakes should you watch for?

The eastern cottonmouth is dark, heavy-bodied, and often found near water. The copperhead has hourglass markings and is most active at night. Timber rattlesnakes have a distinct rattle and broad head. The coral snake has red, yellow, and black bands (red touching yellow). Most bites occur when people accidentally step on or try to handle these snakes. Keep a respectful distance.
