Understanding Venomous Spiders In Washington State
Though the majority of spiders in Washington are harmless, the state is home to a few species of venomous spiders. While spider bites rarely cause significant medical issues, it is still important to educate yourself on spider identification and proper safety precautions in areas where venomous spiders reside.
Black Widow Spiders
Perhaps the most infamous venomous spider in North America, the black widow spider is present across Washington state. Distinguished by the red hourglass shape on its abdomen, the black widow spider's venom is a powerful neurotoxin.
Though black widow bites rarely kill humans, their bites can cause severe muscle pain, nausea, vomiting, headache and other systemic issues. Seek medical care if bitten by this spider.
Brown Recluse Spiders
Brown recluse spiders are identifiable by the violin-shaped marking on their cephalothorax. Their venom destroys skin tissues leading to painful lesions and tissue death at the bite site. Though uncommon, more serious complications can arise.
Though most prevalent in central and eastern regions of Washington, brown recluse spiders have been spotted statewide. Exercise caution in cluttered, dry areas where these spiders dwell.
Hobo Spider
Another venomous spider making its home across the entire state of Washington is the hobo spider. They have a large abdomen and aggressive predatory behavior. Their venom can destroy red blood cells and skin at the bite site.
See a physician promptly if bitten by this fast moving spider common in dark recesses of homes, garages and wood piles. Avoid provoking these spiders.
Signs Of Spider Bites In Washington
The majority of spider bites only result in mild symptoms limited to redness, irritation and itching near the puncture site. However, venomous spiders can elicit more dangerous reactions including:
Intense Pain At The Bite Location
Crippling muscle cramps, pain and spasms around the bite warrant medical evaluation as these can indicate venomous spider bites in some cases.
Nausea, Vomiting And Headache
Feeling sick, vomiting or headaches after a bite may signal a mild or moderate poisoning from a spider like the black widow if these symptoms emerge alongside
