Have you been noticing more spiders in your house lately? You’re not the only one.

Many homeowners in California deal with this same issue, especially during certain times of the year. Whether it’s daddy long legs in the bathroom or a black widow in the garage, it usually means your home has what spiders are looking for.

Let’s go over the most common reasons spiders might be moving in and what you can do to stop them.

Key Takeaways

  • Spiders become more active during late summer when they look for quiet, warm places like inside your home.
  • Spider infestations grow when your home also has other pests like fleas, cockroaches, or bed bugs for them to eat.
  • Cluttered rooms, damp areas, crawl spaces, and outdoor lights all create perfect hiding spots for different spider species.
  • Pest control experts can offer a free quote to help homeowners with spider control using proven treatments.

Spiders Get Active During Mating Season

Spiders are most active in late summer. That’s when many spider species go looking for mates and safe places to lay eggs. Inside your home is warm and quiet—exactly what they want.

How to fix it: Seal up cracks, crevices, and other entry points using caulk or weatherproof tape. Pay close attention to crawl spaces, vents, and pipes going into your home.

Other Bugs Are Attracting Them

If you’ve got cockroaches, fleas, or bed bugs, spiders will follow. These pests are food sources for arachnids. So if you have one infestation, you could end up with a growing spider population, too.

How to fix it: Schedule pest control services to get rid of any other bugs in your home. This cuts off the spider’s food supply and helps keep spiders away.

Basements, Attics, and Crawl Spaces Are Spider Favorites

These parts of your home are quiet and dark—perfect for spiders. They’re also full of hiding spots and cobwebs, especially if you haven’t cleaned in a while.

How to fix it: Vacuum regularly and remove old boxes or clutter. A pest control professional can treat these areas to stop the spread of spiders and other pests.

Plants and Wood Close to the House

Spiders often start outside, especially around woodpiles, bushes, or ivy that touches your home. If you’re seeing spider webs near your porch or windows, that could be why.

How to fix it: Trim back plants and keep wood at least 20 feet away. Use preventative measures like sealing gaps and spraying around the foundation.

Clutter Inside the House

Spiders like to hide in closets, boxes, under furniture, and in other quiet areas. These hiding spots help them stay out of sight while they build webs or hunt for bugs.

How to fix it: Keep your home organized. Use plastic bins instead of cardboard. Don’t forget to check closets and under beds regularly for signs of spiders.

Damp Areas Attract Bugs (and Spiders)

Basements, bathrooms, and laundry rooms can be damp. This brings in other bugs, which attract spiders. Over time, this can turn into a bigger pest problem.

How to fix it: Fix any leaks and use a fan or dehumidifier to keep these areas dry. Good airflow makes your home less inviting for bugs and the spiders that eat them.

Outdoor Lights Can Draw Spiders In

Bright lights bring in flying bugs at night. Spiders hang out nearby so they can catch them. If you see spider webs near porch lights, this could be the reason.

How to fix it: Use yellow light bulbs or motion-sensor lights. Move lights away from doors and windows if possible.

Small Cracks and Gaps in the House

Spiders can get inside through tiny holes in walls, around windows, or through the garage. Some of these spots may also let in termites or other bugs.

How to fix it: Seal cracks around the outside of your house. A pest control expert can inspect problem spots and help protect your home from multiple pests.
