Giant House Spiders play a crucial role in regulating insect populations, acting as natural pest controllers in our homes. Their presence contributes to a balanced ecosystem, even within human dwellings. They exhibit a nocturnal lifestyle, actively hunting their prey during the night and retreating to their funnel-shaped webs during the day. Part of the Eratigena genus, these spiders may have a large appearance, but they’re actually quite harmless. They have simple eyesight, only distinguishing between light and shadow. Reactions vary from person to person, but hobo spiders are not considered toxic to humans, according to the University of California's Pest Management Program.
Giant House Spider Facts & Information
Identifying features of the grass spiders are the distinctive dark brown bands running down its cephalothorax, mottled brown abdominal patterns, and spiny, orangey legs. The black house spider is a robust spider with a dark, charcoal-gray abdomen and white speckles. In addition, the spider has a characteristic velvety blackish-gray body and furry legs. Its large, egg-shaped abdomen and color give it the appearance of a tarantula. Identifying common house spiders is a great way to ensure you handle them correctly.
Geographic Range of the giant house spider in the United States and its habitat
The Southern House spider is most common in the Southern United States, with some distribution along the Southern West Coast. However, their presence can be lessened by keeping a clean environment. Clear away any debris around your home, seal any cracks they might use to get in, and vacuum storage spaces. The front row of four eyes are on roughly rectangular, flat “faces”, and are larger than the posterior four located at the highest point of the carapace. There is no effective antivenom, but if you’ve been bitten, you should obtain medical care immediately. If you believe you’ve been bitten by a Black Widow spider, or feel any of these symptoms, get medical help immediately.

Spiders typically don't go out of their way to bite something that they can't eat. A giant house spider may bite a person in self-defense, but its venom is only harmful to those with specific allergies. Aside from their large size and menacing appearance, this species doesn't pose much of a threat to people. Protect your home or business from giant house spiders by learning techniques for identification and control. As its name suggests, the common house spider is the spider most often seen in homes in the United States. They like to build webs in hidden areas of the home, such as attics, basements, sheds, and barns.

We’re not likely to see them unless their webs get disturbed or it’s mating season, which happens to be now. From early August to mid-September, “mature males leave their webs to wander in search of mates and can run like the wind,” Crawford explained. Don’t look now, but a spider the size of your palm may be in your house and this is the time of year it’s most likely to make an appearance. Yes, Giant House Spiders are venomous, but their venom is not harmful to humans. If you suspect you have been bitten by a brown recluse, ice and elevate the bite while you monitor it.
Brown widow spiders are typically found in dark, undisturbed areas of your home like behind furniture, basements, attics, or garages. Though you can certainly vacuum any sacs you find on your own, it’s best to contact a pest control professional, as Yellow Sac Spiders are venomous and caution should be used. Yellow Sac spiders commonly feed on other spiders, as well as agricultural and garden pests and their eggs. Their preferred habitats are in dark spaces in the yard, but they will invade homes in search of warmth during the colder months.

Although spiders and insects are arthropods, insects only have 6 legs and are in the class Insecta. Another difference when identifying spiders is that they have 2 body parts whereas insects have 3 body parts. Mature males have swollen palps that look like boxing gloves at the end of each leg. You may want to bring yourself up to scratch with this UK house spider, because you’ll most likely come across one in your home at some point.
They’re a pale beige to yellow color which can even present a hint of green, while the tips of their legs are dark brown. Signs of an Southern House spider infestation are the presence of adult spiders, their spiderlings, webs and egg sacs. Prevention should concentrate on sealing any entry point cracks in the home, removing ground litter outside the home, and minimizing the spider’s food source. They’re usually yellowish-brown with a dirty white, elongated abdomen with spots. Though most North American homes only house three or four common spiders out of the almost 4,000 known species, spiders are almost universally disliked.
In Fact, House Spiders Can Be Helpful
"Spiders feed on common indoor pests, such as roaches, earwigs, mosquitoes, flies and clothes moths," explains a fact sheet by Bayer CropScience. "They usually spend their entire life cycle in, on or under their native building." The giant house spider was introduced to British Columbia, Canada, around 1900 and has since spread out along the U.S. Independent populations have also been recorded around the Great Lakes in Wisconsin and Michigan.
Usually, harvestmen are small, with their bodies not growing more than 0.28” (7 mm) long. However, they have a characteristic large leg span, sometimes up to 6.3” (160 mm) in length. Usually, noticing a hobo spider in the home causes panic because there are incredibly agile, swift-moving spiders. The cellar spider also goes by common names like vibrating spiders, carpenter spiders, and daddy long-legs spider. However, the name daddy long-legs is also given to other arthropods like harvestmen and crane flies. A good place to start looking is our list of top ten pest control companies.
Shining a light on them may cause an eerie glow from their eyes as the light reflects back. Also, wolf spiders are the only species to carry their tiny baby spiders (spiderlings) on their abdomen. Wolf spiders are a subclass of arachnids belonging to the family named Lycosidae.
Other species include the European black widows (Latrodectus tredecimguttatus), Australian redback black widows (Latrodectus hasseltii), and South African button spiders. You can identify spiders by their eight legs, the color of their abdomen and cephalothorax (head), six or eight eyes, and mouthparts (chelicerae). In addition, some spiders have identifiable markings such as spots, dots, or spiny bodies and legs. Spiders are arthropods that belong to the class of animals named Arachnida and order Araneae. These genera include species such as funnel-web spiders, orb-weaver spiders, sac spiders, wolf spiders, and hunting spiders.
In addition, there are two rows of darker brown spots on the underside of the spider’s abdomen. Although the female black widow spiders can inflict a nasty bite, the bites rarely cause serious complications. Some common effects of a black widow bite are pain, swelling, and cramping. The most famous is the black widow spider that can cause a non-fatal nasty bite. However, venomous spiders can also be brown, black with white spots, or black with a red body.
The giant house spider has been treated as either one species, under the name Eratigena atrica, or as three species, E. As of April 2020[update], the three species view was accepted by the World Spider Catalog. Brown widow spiders are also found in yards under rock piles, wood piles, and other sheltered areas. These brown spiders are common in Arizona, Florida, California, and other southern states. Identifying features of the common American house spider are its bulbous dark brown body with mottled patterns, long creamy-white and tan legs, and a small, brown-colored head.
