Frequently Asked Questions

Behavior, Diet & Habits

Understanding House Spiders

Appearance

  • Size: Female common house spiders measure 5 to 8 mm in length, while males measure only 4 mm.

  • Color: Common house spiders are typically brown or gray in color, with darker chevron markings along their bodies.

  • Body: A house spider’s body is divided into the cephalothorax and the abdomen. Like scorpions, mites and ticks, house spiders are wingless.

  • Eyes: Eight, single-lens eyes

Habitat

Common house spiders are abundant in dark or musty areas, such as basements, crawlspaces, attics, and closets.

Funnel Shaped Webs

House spider webs are irregularly shaped and can be located in various places within a home, including windows, ceiling corners and above or beneath fixtures.

Webs are designed as trapping mechanisms and are funnel-shaped, with the narrow end acting as a den for the arachnid. Any contact made with the web produces vibrations throughout the strand, signaling to the common house spider that prey is present. Although common house spiders feed primarily on insects, they may also consume larger spiders, scorpions, rodents and small reptiles.

Cobwebs

The presence of common house spiders is typically characterized by the formation of cobwebs. These silken thread structures can be found throughout infested homes. This abundance of empty webs is caused by the common house spider's propensity to spin webs in various locations until it finds the most suitable place to catch prey.

Signs of a House Spider

Signs of house spider infestations include the spider and their webs.
