Jumping spiders, wolf spiders, cellar spiders and brown recluse spiders all have at least one thing in common -- they want to be inside your home and even in your bedroom. Most spiders are harmless, but that doesn't mean you want them as roommates. Eradicating spiders from a room starts by preventing migration into the home. Clean up debris around the yard and use yellow vapor lights outdoors to deter insects that spiders feed on.

Things You'll Need

  • Broom
  • Vacuum sweeper
  • Insecticide
  • Mesh screen
  • Tape

Keep firewood and lumber away from the house to eliminate hiding places. Cut back shrubs and vines adjacent to the foundation and clean up leaves and litter. Caulk cracks and crevices in the foundation and around windows and trim. Cover windows with tight-fitting screens to prevent spiders and their food supply, such as flies, ants and cockroaches from entering your home. Install mesh screen over vents and roof gables. Sweep spider webs away from shutters, guttering or tight areas on the exterior of the home. Alternatively, use a high-pressure wash to clean off egg sacs and webs.

Spray an insecticide, such as Carbaryl or synthetic pyrethroids around the perimeter of the foundation to act as a barrier. Spray the garage door entrance, crawl space and door thresholds to prevent migration indoors. The University of California Statewide Integrated Pest Management Program deems spraying spiders directly to be ineffective.The program recommends a professional application of sorptive dusts that contain amorphous silica gel and pyrethrins for indoors. Alternately, use sticky traps in nooks and crannies where spiders live.

Inspect the garage, basement, attic and interior of your home for spiders, webbing or eggs. To avoid bites, carefully remove old boxes, piles of clothing, paper and general clutter. Dispose of old boxes outdoors, then shake out and repackage items in new boxes. Tape boxes shut or use plastic bags with ties to prevent future spider habitation. Move boxes and containers away from walls. Remove clutter under beds and move the bed away from the wall. Take off the bed skirt or dust ruffle to prevent spiders from climbing onto the bed. Put shoes on a shoe rack and keep clothing picked up. Avoid letting items accumulate on the floor.

Crush or capture and release spiders outside after your have sealed up the house. Capture a spider by placing a glass over it and sliding a paper underneath the glass.

Vacuum thoroughly throughout the house by using attachments to reach nooks and crannies where spiders hide. Remove the vacuum bag and empty it into a container outside. Sweep hardwood, ceramic and vinyl floors, as well as ceiling corners. Clean up all evidence of spiders, egg sacs and webbing. Adopt a weekly cleaning regimen to prevent spiders from taking up residence in your home.

Tips & Warnings

  • Prevent spider bites by shaking out clothing and shoes before wearing them.
