What to look for
In Washington, the venomous species to know are northern Pacific rattlesnakes. The harmless snakes you'll see most in Washington are gopher snakes, garter snakes, racers, and rubber boas, and they're the ones doing useful work eating rodents. But a snake sighting in Washington is rarely the actual problem — it's a signal. Snakes come for food, cover, and a way in, and removing those stops them.
- 1In Washington, the clearest sign is seeing the same snake — or the same size and color — in the same spot more than once.
- 2A shed skin in a undefined garage, crawl space, or garden bed means a snake spent real time there and grew.
- 3S-shaped drag marks in dust, sand, or loose soil around undefined show you a snake's travel route and often lead to the gap it uses.
- 4Mice, rats, or frogs around a undefined home are the food snakes follow — their presence is an invitation.
- 5A musky smell in an enclosed space like a undefined crawl space or shed can mean a snake has been disturbed there, sometimes repeatedly.
- 6Rustling under floors or disturbed insulation in a undefined attic is worth checking — rat snakes climb and follow mice up.
Why it’s worth acting soon
- Waiting in Washington means another day a venomous snake could bite — and most bites happen when someone tries to move or kill it.
- A snake that found a way into a Washington home can find it again until the gap is sealed; the opening doesn't close itself.
- One snake in spring around Washington can become a litter by summer, since several common species give birth to live young.
- The cover and food that drew a snake to a Washington property keep drawing the next one until you change them.
