If you’ve ever walked into your basement or garage and spotted long, skinny-legged spiders hanging in messy webs, chances are you’ve met the cellar spider.
Sometimes called “daddy longlegs,” these critters are a common sight in Kansas City homes, especially in dark, damp spaces. While they aren’t dangerous, having them around can make a basement feel less welcoming.
The good news? With a little know-how, you can keep your cellar spider population under control.
TLDR: Cellar spiders are harmless but often unwanted in basements and garages. They thrive in damp, cluttered areas where other insects are present. Keep them out by reducing moisture, sealing entry points, vacuuming webs, and limiting other pests. If they keep coming back, professional eco-friendly pest control can provide long-term relief.
What Are Cellar Spiders?
Cellar spiders are light brown or gray in color, with thin legs that make them look much larger than they actually are. They spin irregular, tangled webs in out-of-the-way corners, often high up in basements, crawl spaces, or garages.
It’s worth noting that not all “daddy longlegs” are cellar spiders; harvestmen (which don’t spin webs at all) are often confused with them. Cellar spiders prefer cool, damp environments, which is why basements and storage areas are some of their favorite hiding places.
Are Cellar Spiders Dangerous?
Despite their spooky appearance, cellar spiders are harmless to humans and pets. In fact, they can actually help control other pests in your home by trapping small insects in their webs.
There’s even a popular myth that cellar spiders are “the most venomous spider in the world,” but their fangs are too small to bite people. That simply isn’t true. The reality is, they pose no threat to you or your family; they’re just unwelcome houseguests when their webs start taking over your basement corners.
Why Do I Have Cellar Spiders in My Home?
If you’ve noticed more cellar spiders than usual, it’s usually a sign that your home is offering them exactly what they want. These spiders are attracted to three main things:
- Moisture – Basements, crawl spaces, and garages often stay damp, making them ideal hiding spots.
- Food – Cellar spiders eat other insects, so if you’ve got a bug problem, you’ll likely see more spiders too.
- Shelter – They love cluttered spaces, where boxes, furniture, and storage bins create dark corners for webs.
Understanding what’s drawing them in is the first step to keeping them out.
How to Get Rid of Cellar Spiders Naturally
The good news is, you don’t need harsh chemicals to tackle cellar spiders. A few simple habits go a long way:
- Reduce clutter – The fewer hiding places you give them, the fewer webs you’ll see.
- Vacuum regularly – Remove webs, egg sacs, and spiders all in one go.
- Seal entry points – Caulk cracks, gaps, and openings around windows and doors.
- Control moisture – A dehumidifier in the basement can make the space less inviting.
- Limit other pests – Since spiders go where the food is, tackling other bugs will reduce their numbers too.
Consistency is key. These steps don’t just get rid of cellar spiders. They help prevent them from coming back.
When to Use Professional Spider Control
Most homeowners can handle the occasional spider with regular cleaning and prevention. But if you’re dealing with heavy webbing, repeated infestations, or suspect you’ve got other pest issues feeding the problem, it may be time to call in the professionals.
A spider control service can identify the root cause, treat spiders at the source, and set up long-term prevention.
