Habitats

Any corner inside or outside is suitable for house spiders to construct their webs. These spiders are more common in garages, crawl spaces and basements as these areas are less disturbed and tend to harbor more insects.

Tips for Control

  • Regular removal of spider webs is the best way to limit these spiders.

  • Sealing up cracks around windows and doors helps prevent their entry.

  • Switch exterior lights to the yellow "bug light” bulbs, which attract fewer flying insects on which spiders feed.

  • Treatments to exterior spider nesting sites can help reduce the numbers of spiders when combined with an overall pest management program.
