North America is home to about 3,400 species of spiders. Spiders are arachnids, and they’re related to scorpions, mites, and ticks. Unfortunately, spiders can and do make their way into our homes. Thankfully, the most common types of house spiders are harmless to humans, but there are exceptions.

American House Spider (Parasteatoda tepidariorum)

The American House Spider is a comb-footed spider, a common type known for its webs. They’re part of a group known as cobweb spiders, usually building the webs in places like basements, closets, and crawl spaces. 

  • Color: Brown, tan, or greyish with darker brown patterns
  • Size: small to medium (about the size of a nickel including the legs)
  • Features: rounded abdomen

Typically harmless, these spiders create messy webs that look unsightly.

Long-Bodied Cellar Spider (Pholcus phalangioides)

Sometimes referred to as daddy longlegs, the long-bodied cellar spider is actually not the same thing as a true daddy longlegs, which is a harvestman arachnid with just one body section and two eyes, according to The Burke Museum. Spiders, like the long-bodied cellar spider, have two body sections and usually eight eyes.

The long-bodied cellar spider builds webs, often in basements, cellars, crawl spaces, garages, and other dark spaces. 

  • Color: light brownish-tan, beige, or grey
  • Size: small, round body
  • Features: long, skinny legs

The cellar spider is not venomous. 

Brown Recluse (Loxosceles reclusa)

The brown recluse is part of the brown spider family. According to the Department of Entomology at Penn State, the brown recluse is established in 15 states and can be found across the country in climates that range from the high humidity of Florida to the arid desert regions of Arizona and the cooler temperatures of the Midwest. You can find them indoors in basements, attics, crawl spaces, between walls, in furniture, and even in clothing. They’re often carried into the home via boxes and bags. 

  • Color: brown or greyish
  • Size: oval body, about 1/3” long 
  • Features: three pairs of eyes plus dark, violin-shaped marking on body

The brown recluse’s venom has a cytotoxin that can affect the tissue at the bite site. Medical treatment is needed, as dangerous reactions from the venom can occur. These may include but are not limited to chills, fever, rash, pain, and nausea. Children are more sensitive to spider bites than healthy adults and may suffer life-threatening reactions, reports the University of Rochester Medical Center.

Sac Spiders (Families ClubionidaeMiturgidae, and Corinnidae)

Sac spiders don’t make webs. It's typical to discover these spiders near the ceiling or high along the wall. The sac spider is active year-round, usually at night. 

  • Color: light-colored, yellow, beige
  • Size: oval body, about 1/2” long 
  • Features: two rows of eight small eyes

Harmless to most individuals, sac spider bites can produce swelling and slight soreness at the site. Anyone with spider bite allergies or sensitivities may experience a reaction that could need treatment.

Jumping Spiders (Family Salticidae)

Jumping spiders tend to hunt for prey during the day. You may spot them on the inside of a window, screen door, along a wall, or any surface exposed to daylight. They move in quick jumps.

  • Color: brown, black, tan, grey, beige
  • Size: compact, almost an inch long 
  • Features: dense hairs, front legs that are longer than the others

The jumping spider’s bite is similar to a bee sting, but usually harmless. Children or anyone allergic to spider bites may experience a reaction, which can differ from person to person.

Wolf Spiders (Family Lycosidae)

Wolf spiders are larger than many of the other common household spiders. They may enter your home through foundation cracks, windows, or come in through an attached garage. Considered a hunting spider, they eat insects and even can make good pets. 

  • Color: brown, black, tan, greyish-beige
  • Size: large, bodies longer than an inch 
  • Features: elongated body with hairy-looking legs

Harmless to humans, brown-colored wolf spiders sometimes are mistaken for the brown recluse. However, anyone allergic to spider bites may suffer a reaction that could require medical treatment.

Hobo Spider/Funnelweaver (Tegenaria agrestis)

The hobo spider is considered an aggressive spider that builds funnel-like webs. They’re also known as funnelweavers and commonly mistaken for brown recluse and wolf spiders because of their brownish color. You may find them in dark areas of the basement or hiding under the fireplace wood pile. 

  • Color: brown, tan
  • Size: oblong body about 1/2” long
  • Features: solid color with no markings

Funnelweavers or hobo spiders are not dangerous, but some people may experience irritation at the site of a bite. As with other spider bites, children can experience a stronger reaction than an adult.

Removing House Spiders

Even though most common house spiders don’t pose a threat to humans, you may not want them sharing your home. If you have an invasion problem, there are plenty of ways to get rid of spiders. If you’d rather not fight them on the front lines, you can find help from a local spider extermination service.
