How Spiders Get Into Your Home (And How to Stop Them)

Spiders are one of the most common household pests—and one of the most misunderstood. While most spiders are harmless and even beneficial in nature, that doesn’t mean you want them crawling through your bedroom or nesting in the corner of your bathroom.

At Specter Pest Control, we hear from homeowners all the time who are surprised by just how many spiders they’re sharing their home with—especially in the cooler months or after a good rain. The good news? Once you understand how spiders get in, you can take real steps to keep them out.

Here’s what every homeowner should know about spider entry points, what attracts them indoors, and how to create a home environment that makes them think twice about sticking around.

Why Spiders Come Indoors in the First Place

Let’s start with one simple truth: Spiders aren’t trying to bother you. They’re typically looking for three things—food, shelter, and moisture—and if your home checks those boxes, it becomes an ideal hiding place.

Common reasons spiders move indoors include:

• Insects to eat (flies, ants, silverfish, etc.)

• Dark, quiet spaces to spin webs or lay eggs

• Temperature changes—especially when it gets cold or wet outside

• High humidity in basements, bathrooms, or garages

So if you’re seeing spiders, there’s a good chance other pest issues are at play too.

How Spiders Get Into Your Home

Spiders are resourceful—and small. That means they can slip through entry points you might never notice. Some of the most common access points include:

• Gaps around doors and windows

• Cracks in siding or foundation

• Torn window screens

• Vents, chimneys, and utility lines

• Gaps under garage doors or crawl space hatches

• Piles of wood or debris stacked against the house

And they don’t need much. A spider can get through an opening as small as 1/16 of an inch.

Signs You Might Have a Spider Problem

While the occasional spider sighting isn’t unusual, more frequent activity could mean a larger infestation. Here are a few signs to watch for:

• Multiple webs in corners, window frames, or ceiling edges

• Egg sacs (small white silk balls) tucked away in hidden areas

• Spiders appearing in multiple rooms of the house

• Sudden increase in flying insects (spiders follow the food)

If you’re spotting spiders often—especially during daylight hours—it may be time for a closer look.

How to Keep Spiders Out of Your Home

Spiders might be sneaky, but keeping them out isn’t impossible. With a mix of good home habits and professional pest control, you can create a home that’s a lot less welcoming to them.

1. Seal Up Entry Points

Walk the perimeter of your home and look for cracks, gaps, or broken seals around doors and windows. Repair screens, use weatherstripping, and apply caulk where needed.

2. Declutter and Clean Regularly

Spiders love quiet, undisturbed areas. Keep closets, garages, attics, and basements clean and clutter-free. Vacuum webs and egg sacs when you find them.

3. Control Other Pests

Spiders go where the food is. A general pest control plan that reduces insect populations will naturally reduce spider interest in your home.

“If we eliminate their food source, spiders won’t want to stick around,” says the Specter team. “That’s why our service includes general pest control—it’s about solving the whole problem, not just part of it.”

4. Manage Moisture

Use dehumidifiers in damp areas and fix any leaks or plumbing issues. Spiders—and their prey—love moisture.

5. Be Mindful of Outdoor Conditions

Keep shrubs and plants trimmed away from your home’s exterior. Avoid stacking wood or storing items against your foundation.
