Found a Dead Snake in Your Yard? What to Do
A dead snake gets a different reaction than most of what I write about — usually more startle than grief. Washington's own wildlife agency has real, specific facts on this that make the honest answer more reassuring than most people expect, especially here in Pierce and Thurston County.
What Snakes Actually Live Here
Washington is home to 12 native snake species, per the state's own Department of Fish and Wildlife. In the Puget Sound lowlands specifically, the common ones are the northwestern gartersnake, the common gartersnake, the terrestrial gartersnake, and the northern rubber boa — all genuinely harmless. One species worth mentioning for local color: the gopher snake (bullsnake) was historically found on south Puget Sound prairies in the late 1800s, but WDFW notes it hasn't been verified present in western Washington since, and is considered possibly extirpated from this side of the state. If you're picturing a big, thick snake, what you actually found was very likely a gartersnake or rubber boa.
The One Venomous Snake — and Why It's Not Really a Pierce/Thurston Concern
WDFW is direct: of the roughly dozen snake species in Washington, only the western rattlesnake is capable of a venomous bite, "which it seldom does." And here's the real, reassuring regional fact — WDFW's own range data places the western rattlesnake east of the Cascade Mountains, in the drier Columbia Basin, Okanogan, and Blue Mountain regions. The westernmost confirmed record is about a mile west of Dog Mountain in Skamania County, in the Columbia River Gorge — nowhere near the Puget Sound lowlands. That's not a guarantee a rattlesnake could never turn up here, but it's a real, sourced fact that this area sits well outside its documented range.
How to Tell a Rattlesnake From a Harmless Snake
WDFW points to a few real, visual cues: a rattle at the tip of the tail (the only Washington snake with one), a broad triangular head noticeably wider than the neck, and a dark, diamond-blotched pattern with a black-and-white bordered edge. Worth being honest about the limits here — a young rattlesnake's rattle can be a single silent "button" segment, and some harmless snakes flatten their heads defensively when threatened, which can blur these cues in the moment. WDFW's own consistent advice is simpler than trying to identify a snake up close: observe from a distance and leave it alone, rather than relying on a close-range ID to decide whether it's safe to approach.
Is the "Reflex Bite After Death" Thing Actually Real?
Yes — this one is genuinely documented, not internet exaggeration. A peer-reviewed review confirms the bite reflex in recently killed or even decapitated venomous snakes can remain intact for a period after death, with one cited case of a rattlesnake head still capable of biting weeks after being separated from the body. The same review is honest that actual medically confirmed cases are rare relative to how often the warning gets repeated. Given that Pierce and Thurston County fall outside the rattlesnake's documented range, this is more of a general safety fact than a locally urgent one — but it's still a real reason not to handle any dead snake you can't positively identify as harmless.
What Washington Law Says
Snakes are wildlife under Washington's own statutory definition, which means the same rule that applies to deer or any other found-dead wildlife technically applies here too: notify WDFW or the Washington State Patrol by phone before removing a dead snake from your property. Washington's general dead animal disposal rule also appears to apply based on its own broad definition of "dead animal" — burial at least three feet deep, at least 100 feet from any well or water source, handled within 72 hours.
What to Actually Do
- If you're not confident it's a harmless species, don't handle it — a reflex bite from a freshly dead venomous snake is a real, documented phenomenon
- Look for a rattle, a triangular head, and diamond-blotched pattern as real (if imperfect) warning signs
- Call WDFW or WSP before removing it, since Washington law requires notification before removing wildlife found dead on your property
- Remember: this area sits well outside the western rattlesnake's documented range, so a gartersnake or rubber boa is by far the more likely find here
Frequently Asked Questions
Are there venomous snakes in Pierce or Thurston County? Washington's only venomous snake, the western rattlesnake, has no documented range in the Puget Sound lowlands — its confirmed range is east of the Cascades.
Can a dead snake still bite you? Yes — this is a real, peer-reviewed documented phenomenon in recently killed venomous snakes, though actual confirmed cases are uncommon.
How can I tell if a snake is venomous? A rattle, triangular head, and diamond-blotched pattern are real cues, but WDFW's own advice is to observe from a distance rather than rely on close-range identification.
Do I need to call anyone before removing a dead snake from my yard? Washington law technically requires notifying WDFW or WSP before removing any wildlife found dead on your property, snakes included.
