Why Are There So Many Spiders in My House in Spokane?

Spokane homeowners often see spiders indoors because the city’s seasonal climate and local environment provide abundant shelter and food. Common reasons include:

  • Cold or wet weather driving spiders indoors in fall and winter

     

  • Abundant insect populations, which attract spiders

     

  • Cluttered or undisturbed areas like basements, attics, and garages

     

  • Entry points such as cracks in windows, doors, and foundations

     

While spiders are generally harmless, a large indoor population can be concerning. Proper home maintenance and targeted pest control can significantly reduce spider activity.

Why Spiders Enter Homes in Spokane

1. Seasonal Behavior

Spiders are most active indoors during:

  • Fall & Winter: seeking warmth and shelter from cold Spokane winters

     

  • Spring & Summer: some species may wander indoors while hunting

     

2. Food Sources

Spiders feed on insects. High insect activity around:

  • Gardens and lawns

     

  • Outdoor lights

     

  • Wood piles and debris

     

…often translates into higher spider presence inside the home.

3. Shelter and Clutter

Spiders like quiet, undisturbed spaces:

  • Basements

     

  • Garages and sheds

     

  • Attics and crawlspaces

     

  • Under furniture or boxes

     

Keeping these areas clean and organized helps deter indoor spiders.

4. Entry Points

Common ways spiders enter homes:

  • Cracks around windows and doors

     

  • Gaps in foundation or siding

     

  • Vents, screens, or utility openings

     

Sealing these points can prevent most spider intrusions.

Common Spider Types in Spokane Homes

    • House spiders: small, non-aggressive, usually harmless

    • Hobo spiders: occasionally bite, mostly outdoor but can enter homes

    • Jumping spiders: harmless, often seen near windows

    • Black widows: rare indoors but dangerous if encountered

Why DIY Spider Control Often Fails

  • Sprays may kill visible spiders but not eggs

     

  • Sticky traps capture only a small portion

     

  • Spiders continue to enter through unsealed entry points

     

Professional spider control focuses on both immediate removal and long-term prevention.

How to Reduce Spiders in Your Spokane Home

  • Seal cracks and gaps around doors, windows, and foundation

  • Reduce clutter in basements, attics, and storage areas

  • Remove outdoor debris and woodpiles near your home

  • Install proper door sweeps and screens

  • Use preventative exterior pest treatments to reduce insects spiders feed on

When to Call a Professional

  • Spider numbers are high despite DIY efforts

     

  • You see dangerous species like black widows
