Common House Spiders: How They Get In, Where They Hide, and How to Keep Them Out

If you’ve ever spotted a spider crawling across your living room wall or weaving a web in the corner of your garage, chances are it’s a common house spider. While these spiders aren’t usually dangerous, they’re certainly unwelcome guests. Knowing how house spiders get into your home, where they like to hide, what they eat, and how to prevent and treat infestations will help you keep your home comfortable and pest-free.

How Do Common House Spiders Get Into Homes?

House spiders are sneaky and can slip inside through the smallest openings. The most common entry points include:

• Cracks and gaps in doors, windows, or your home’s foundation

• Torn or loose window screens

• Utility openings around plumbing, vents, or cables

• Open garage doors and poorly sealed attics

Once inside, spiders look for two things: shelter and food. If your home has plenty of hiding spots and insects, it’s the perfect place for them to settle.

Where Do House Spiders Like to Hide?

House spiders prefer quiet, dark areas where they won’t be disturbed. Some of the most common hiding spots in Rialto and Fontana homes include:

• Basements, garages, and attics

• Closets, under beds, and inside storage boxes

• Behind or underneath furniture and appliances

• Ceiling corners, window frames, and around porch lights

They’re patient hunters, setting up webs in these hidden areas to trap insects while staying out of sight.

What Do Common House Spiders Eat?

House spiders survive on a steady diet of insects. Their meals often include:

• Flies, gnats, and fruit flies

• Ants and small crawling bugs

• Moths, mosquitoes, and other flying insects

If you’ve noticed an increase in spider activity, it could mean your home has a healthy insect population that’s drawing them in.

How to Prevent House Spiders from Moving In

The best defense against house spiders is making your home less attractive to them. Here are a few prevention tips:

1. Seal cracks and gaps – Use caulk around windows, doors, and your home’s foundation.

2. Install and repair screens – Keep bugs (and spiders) from coming in through torn screens.

3. Reduce clutter – Organize storage areas and avoid stacking cardboard boxes where spiders like to hide.

4. Vacuum regularly – Remove webs, egg sacs, and insects that attract spiders.

5. Limit outdoor lighting – Bright lights attract flying insects, which in turn bring spiders closer to your home.

Treating a Spider Problem

DIY methods like knocking down webs and sealing gaps can help, but once house spiders establish themselves, they can be tough to eliminate completely. Sprays may kill a few, but they don’t address the root of the problem—other insects living in your home or yard.
