Watch: Spider Talk – Fact or Fiction from our team at Interstate Pest Management. In this episode of Tech Talks, we explore spider myths, local legends, and the truth behind our eight‑legged neighbors in the Pacific Northwest. Below, we’ve expanded on what we discussed — adding expert context and homeowner tips to help you feel confident living alongside (or a little apart from) the spiders that share our region.
Common Spiders in the Pacific Northwest
The Pacific Northwest is a haven for spiders, thanks to our mild, damp climate and lush landscapes. Before we settle some common myths, let’s get to know some of the species that most often share our homes and gardens across Portland, Vancouver, and Longview.
“Most spiders aren’t here to scare you — they’re here to eat what would otherwise bug you.”
Sheetweb Spiders spin expansive horizontal webs across shrubs — little dew‑covered hammocks that gleam after rainfall. They’re among nature’s best pest controllers, quietly reducing insect populations around gardens and landscaping.
Crab Spiders show off remarkable camouflage skills. Common in Willamette Valley gardens, they blend into flowers so well that even experienced pest pros can mistake them for petals.
Orb‑Weaving Spiders are the architects of those classic circular webs that seem to appear overnight near porch lights. They almost never live indoors, but their webs can be unsightly if they’re decorating your front door.
Jumping Spiders bring unexpected charm. Small, shiny, and occasionally curious enough to observe humans back, they’re agile hunters that keep smaller insects in check.
Indoor Spiders such as ground spiders and long‑legged sac spiders prefer the shelter of basements, trim boards, and ceiling corners. Most are fast, shy, and gone before you even realize what you saw. The infamous funnel web (hobo) spiders often mistaken for dangerous invaders, fall into this group too.
Fact or Fiction: Separating Northwest Spider Myths
Here in the Northwest, spiders are often at the center of local legends and late‑night stories. Let’s set the record straight by separating a few common myths from what we actually see in homes across Washington and Oregon.
“The more you understand about spiders, the less scary they become — and the easier they are to live with.”
Myth: Brown Recluse Spiders Live in Washington or Oregon.
Reality: Not true. Brown recluse spiders do not naturally occur here — those big brown ones you’ve seen are likely harmless cousins like hobo or giant house spiders.
Myth: Hobo Spiders Are Aggressive.
Reality: False. Their venom isn’t medically significant, and they don’t go hunting for humans. They bite only if threatened — not for fun.
Myth: There Are No Dangerous Spiders in the Pacific Northwest.
Reality: Mostly true — but with one small red hourglass‑shaped exception.
Black widow spiders
can be found occasionally, particularly in southern Oregon. They’re rare, shy, and seldom cause serious problems.
Myth: Daddy Longlegs Are the Most Venomous Spiders in the World.
Reality: Completely false.
Opiliones —
also known as harvestmen or “daddy longlegs” — aren’t spiders at all and lack venom and silk glands entirely.
Myth: A Spider Flushed Down the Toilet Will Return for Revenge.
Reality: We get this question more often than you’d think! But don’t worry — scientifically, the answer is no.
