Where Spiders Hide in Olympia Homes (and How to Spot Them)
</h1>

Image

You walk into the basement for a storage box and spot a web in the corner. A few days later, you see another in the garage and start to wonder: are more spiders hiding nearby?
Spiders are common in Olympia, but they still feel unsettling indoors. They slip into basements, attics, and crawl spaces, capitalizing on our damp climate. Many homeowners do not notice the many hiding spots until webs and sightings increase.
Wonder where spiders go? Learn their favorite hiding places so you know what to look for and when to act.
This guide covers the most common hiding spots for spiders in Olympia homes and guides how to identify them early. You will also learn why spiders move in and how professional spider control protects your home in the long term.

</ul>
<h2 dir=”ltr”>Common spider hiding spots in Olympia homes</h2>
Spiders like dark, quiet areas where people rarely go. Basements, attics, and garages offer shelter and low traffic. Crawl spaces are often damp and frequently harbor other pests, which provide a steady food source for them. These hidden spots let spiders live and hunt without being noticed.
Indoors, check for webs near windows, under furniture, and behind storage boxes. Giant house spiders and common house spiders often move inside in the fall. Hobo spiders favor basements and crawl spaces. Yellow sac spiders rest along ceilings. Cellar spiders spin thin corner webs.
<h2 dir=”ltr”>Dangerous spiders in Thurston County</h2>
Olympia is home to <a href=”https://doh.wa.gov/community-and-environment/pests/spiders”>many spider species</a>. The <a href=”https://www.wildlifetrusts.org/wildlife-explorer/invertebrates/spiders/giant-house-spider”>giant house spider</a> is common in Thurston County. It appears large and fast, but it typically avoids people and helps control other insects.
<a href=”https://extension.oregonstate.edu/families-health/healthy-homes/how-identify-wolf-spider”>Wolf spiders</a> are also common in Washington. They do not spin webs; they hunt on the ground, often in basements or garages. <a href=”https://www.nwf.org/Educational-Resources/Wildlife-Guide/Invertebrates/Common-House-Spider”>Common house spiders</a> create messy corner webs and usually live indoors.
A few spiders need extra caution. <a href=”https://entomology.wsu.edu/outreach/bug-info/black-widow/”>Black widow spiders</a> are uncommon in Washington, but they can sometimes be found in garages, crawl spaces, or woodpiles. They are shiny black with a red hourglass on the underside. Bites can cause severe pain and cramps. Seek <a href=”https://my.clevelandclinic.org/health/diseases/black-widow-spider-bite”>medical attention</a> for strong symptoms.
<a href=”https://mdc.mo.gov/discover-nature/field-guide/brown-recluse-violin-spider”>Brown recluse spiders</a> are not native to Washington. Many people mistake wolf spiders or hobo spiders for them due to their similar size and color. If you are unsure, call a pest control expert for identification and safe treatment. Local <a href=”https://www.pci-pest-control.com/pest-control”>pest control services</a> provide the knowledge and tools to handle spiders quickly and safely.
<h2 dir=”ltr”>Why Olympia homes attract spiders year-round</h2>
Olympia’s cool, wet climate helps spiders thrive. Homes near trees, gardens, and water often see more activity. Woodpiles by the house, garage clutter, and damp crawl spaces make it easy for spiders to move in.
In late summer and fall, <a href=”https://www.pci-pest-control.com/blog/common-house-spiders-lacey-and-how-keep-them-out”>spiders in Lacey</a>, Tumwater, and nearby areas often come inside to find mates. They also follow food. If you have <a href=”https://www.pci-pest-control.com/blog/why-youre-seeing-ants-your-olympia-kitchen-every-june”>ants</a>, flies, <a href=”https://www.pci-pest-control.com/blog/flea-infestations-olympia-homes”>fleas</a>, or bed bugs, expect more spiders. Taking <a href=”https://www.pci-pest-control.com/blog/spider-prevention-olympia”>preventive measures</a>, such as sealing entry points, keeping crawl spaces dry, and storing wood away from the home, makes a significant difference.
