Snakes in Washington: Identification Guide
Identify Washington snakes with our guide. Learn about venomous and non-venomous species, plus find snake-themed t-shirts for fans.
The Short Answer: Washington is home to 12 snake species, but only one is venomous: the Northern Pacific Rattlesnake. Most snakes you encounter are harmless and benefit the ecosystem by controlling rodent populations. Learn to identify them and stay safe.
What are the most common snakes in Washington?
Washington has a diverse snake population, with the garter snake being the most frequently seen. Common non-venomous species include the Northwestern Garter Snake, Common Garter Snake, and Western Terrestrial Garter Snake. The only venomous snake is the Northern Pacific Rattlesnake, found in dry, rocky areas east of the Cascades.
Which snakes in Washington are venomous?
The Northern Pacific Rattlesnake (Crotalus oreganus) is the only venomous snake in Washington. It has a broad, triangular head, vertical pupils, and a rattle at the tail tip. Its venom is hemotoxic, but bites are rare. If you encounter one, give it space and leave it alone.
How can you identify a garter snake vs. a rattlesnake?
Garter snakes are slender with stripes running lengthwise, while rattlesnakes are heavier-bodied with a diamond-shaped pattern. Garter snakes have round pupils and a narrow head; rattlesnakes have elliptical pupils and a wide head. Garter snakes lack a rattle and typically flee rather than defend.
What should you do if you see a snake in Washington?
Stay calm and back away slowly. Do not attempt to handle or kill the snake, as most bites occur when people try to capture or harm them. If you're in rattlesnake habitat, watch your step and avoid putting hands or feet into unseen areas.
