Facts

  • Common: While several species of spiders frequently enter homes, none invade manmade buildings with the same persistence as the common house spider.
  • Webs: They spin thin, tangled cobwebs in out-of-the-way spaces, like corners, attics, and basements, and can be found living alongside humans at all times of the year.

Food

What Do House Spiders Eat?
House spiders use their webs to catch common insect pests like:

Biology

Lifespan
After reaching maturity, common house spiders typically live one year.

Life Cycle
After mating, the male sacrifices himself as a meal to his partner to ensure she produces healthy spiderlings. Females lay hundreds of eggs at a time and are capable of producing thousands of offspring over the course of their lives.

Detection

  • Sight: May notice adult spiders during any time of the year.
  • Webs: Look for an abundance of tangled webs in a single area.
  • Eggs: Be alert for papery brown egg sacs.

Problems Caused by House Spiders

Unsightly
These spiders produce a lot of webbing, and tangles of dusty, abandoned cobwebs give off the appearance of uncleanliness.

Nuisance
Common house spiders do not attack humans, but their presence unnerves people with arachnophobia.

Signs of Infestation

Common house spiders are active all year long and do not make much effort to conceal their presence.

Signs of infestation include:

  • Brown egg sacs found in webs.
  • Adults congregating in areas with plentiful food.
  • Spotting a lot of webbing throughout buildings.

Prevention Tips

While it may not be possible to entirely prevent the presence of house spiders, taking steps to eliminate potential food sources and points of entry helps reduce the likelihood of infestations.

Sanitation
Insects which common house spiders regularly feed on, such as flies and ants, can be excluded from the home by keeping regular sanitation schedules.

Exclusion
Potential entryways, such as damaged weather stripping around doors and windows, exposed vents, and gaps in siding, should be covered or repaired to reduce the chance of spiders coming inside.

Tips for Removal from Home

  • Vacuum: A vacuum, duster, or broom is often sufficient to remove the spiders and their cobwebs.
  • Catch & Release: Caught spiders can be released outside in a sheltered location.
  • Consult the Experts: Additionally, individuals can call on the help of professional pest control services to eliminate common house spiders from homes.
