We’ve all heard the nursery rhyme, “Itsy Bitsy Spider,” perhaps so much so that we know its tune and words by heart.
But chances are, if you live in Oregon or Washington, you know that our spiders aren’t always so itsy bitsy, nor are they fun to have around.
While spiders offer a number of benefits to the environment, it’s easy to worry about some of the more dangerous black spiders in Washington State.
In this guide, we’ll introduce you to the species that are friend and foe, and teach you what you can do to keep your home spider-free.
The Most Common Black Spiders in Washington State
Washington State is home to a diverse range of spiders, most of which are harmless and even beneficial.
Due to the region’s mild, often wet climate, most arachnids find Washington to be an ideal, inviting home. Basements, sheds, and garages become prime real estate during the fall months when spiders seek shelter indoors as the temperatures outside drop.
Thankfully, brown recluse spiders, one of the most feared species of spiders, do not live in Washington State, despite being associated incorrectly with many mysterious spider bites. This is your first piece of good news!
However, there are two spiders of medical significance that call this region home:
The Black Widow Spider
Found primarily in eastern Washington, though small populations exist in the west, female black widows are shiny black with the signature red hourglass marking on their abdomen.
They prefer dark, undisturbed spaces like woodpiles, basements, and crawl spaces.
The Yellow Sac Spider
As you’ve guessed from the name alone, yellow sac spiders are not black, though they’re important to note for their medical significance.
Unlike black widows, yellow sac spiders are pale yellow or greenish and much smaller, typically about half an inch long. They’re often found along walls and ceilings or hiding in bedding and clothing.
Are Black Spiders Dangerous?
The majority of spiders are not aggressive and bite only when trapped or threatened, but it’s always good to know the risks of the two most prominent spiders in Washington:
Black Widow Spider Bites
Though rare, black widows can deliver a venomous bite that may cause symptoms such as muscle pain, cramping, and increased blood pressure.
According to the National Poison Data System, about 2,600 black widow spider bites are reported annually, though fatalities are exceedingly rare.
Yellow Sac Spider Bites
Again, though not black, these spiders are quick movers and known to bite when pinned against the skin, often while in clothing or bedding. Their bites can cause redness and minor swelling, though they’re not as dangerous as black widows.
If you’re not sure what type of spider you’ve encountered or concerned about a bite, it’s always wise to consult a professional or seek medical advice.
How to Prevent Spiders in Your Home
Though spiders do play an important role in the ecosystem (goodbye, pesky bugs in the garden!), they’re not exactly the housemates you want lounging around in your bed or closet.
Here’s how you can keep black spiders in Washington State outside where they belong:
- Declutter: Your garage, attic, and basement to remove spider-friendly hiding spots.
- Seal Cracks: Close things up around windows, doors, and walls to prevent entry.
- Vacuum Regularly: Pay special attention to the spots around window frames, corners, and baseboards to remove their webs or eggs.
- Shake It Out: Always shake clothing, shoes, or bedding that’s been stored or unused.
- Keep Exterior Woodpiles and Shrubs Away: Keep these tucked away from your house to reduce hiding and entry opportunities.
