Why Spiders Love Your Home

Homes offer spiders everything they need: shelter from the elements, plenty of hiding spots, and a buffet of insects to eat. They sneak in through cracks, open windows, and even on items you bring inside. Once settled, they often set up webs in quiet corners, basements, or attics.

Common House Spiders You Might See

Let's meet some of the most frequent arachnid visitors. Most of these are more afraid of you than you are of them!

harmless House Spiders

Many spiders you find indoors are completely harmless. They just want to catch flies and stay out of your way.

Daddy Long-Legs (Cellar Spiders) - You know these guys! They have tiny bodies and incredibly long, thin legs. They often hang out in corners or basements. Their venom is weak, and their fangs are too small to pierce human skin. They are great at eating other insects, including other spiders.

House Spiders (American House Spiders) -These are the classic "cobweb" makers. They build messy, tangled webs in corners and under furniture. They are usually brownish-gray with some markings. Their bite is not considered dangerous, though it might cause a small, red bump. They are quite shy and prefer to flee.

Jumping Spiders- These fuzzy, compact spiders are active hunters. They have excellent eyesight and will stalk their prey before pouncing. They are often black, brown, or gray, sometimes with iridescent colors. They are harmless to humans and are quite fascinating to watch.

Orb Weaver Spiders- You usually see these outside, spinning beautiful, wheel-shaped webs. Sometimes, they wander indoors, especially near windows or doorways. They come in many colors and patterns. Their bites are rare and usually cause only mild irritation.

Spiders to Be Wary Of

While truly dangerous spider bites are uncommon, it's good to know which spiders can cause more serious reactions.

• Black Widow Spiders- These are the most well-known dangerous spiders in North America. They are shiny black with a distinctive red hourglass shape on their abdomen. They prefer dark, secluded areas like woodpiles, sheds, or undisturbed corners of basements. Their bite can be painful and cause muscle cramps, nausea, and sweating. If you suspect a black widow bite, seek medical attention.

• Brown Recluse Spiders- These spiders are light to dark brown with a violin-shaped marking on their back. They are common in the central and southern United States, though less common in San Jose. They hide in dark, undisturbed places, like closets, attics, and storage boxes. Their bite can cause a painful sore that takes a long time to heal. Medical attention is important for a suspected brown recluse bite.

• Hobo Spiders- These funnel-web spiders are often found in the Pacific Northwest, including parts of California. They are brown and build messy, funnel-shaped webs close to the ground. While their bites were once thought to be quite serious, recent research suggests they are not as dangerous as black widow or brown recluse bites. Still, a bite can be painful and might require medical attention.

How to Keep Spiders Out of Your Home

Preventing spiders from entering your home is easier than getting rid of them once they're inside.

• Seal Entry Points: Check for cracks in your foundation, gaps around windows and doors, and openings where pipes and wires enter your house. Seal these up to block spider access.

• Clean Regularly: Vacuum and dust often, especially in corners, under furniture, and in basements and attics. This destroys webs and removes potential food sources.

• Reduce Clutter: Spiders love to hide in clutter. Keep storage areas tidy and avoid leaving piles of clothes or boxes on the floor.

• Manage Outdoor Lighting: Outdoor lights can attract insects, which in turn attract spiders. Use yellow "bug lights" that are less attractive to insects.

• Trim Vegetation: Keep bushes and plants trimmed away from your home's foundation. This removes pathways for spiders to get inside.
