Giant house spiders are often attracted to homes in search of prey or mates. They are drawn to quiet, dark areas where they can build their webs undisturbed. The bite of a giant house spider is comparable to the sting of a bee, but usually no more painful than that. The kind of venom they carry is not dangerous to humans, but it may cause pain and swelling in rare instances. The abdomen of the spider is relatively small and lighter, almost yellowish brown and gray, dark brown or black.
Habitat, Diet, Life Cycle & Bites
Based on collected data, the geographic range for Eratigena duellica includes 3 countries and 2 states in the United States. Eratigena duellica is most often sighted indoors, and during the month of April. The giant house spider is often confused with the similar looking hobo spider (Eratigena agrestis) that is also common in the Pacific Northwest. The hobo spider has very similar markings but is generally smaller than the giant house spider and has shorter legs. The related grass spider (Agelenopsis sp.) is also often confused with the giant house spider. These common house guests are particularly unwelcome because they have a venomous bite that is especially dangerous to kids and pets.

It’s a giant house spider and, boy, does it live up to its name. Big, brown and hairy-legged, it lives, eats and mates inside houses, garages and sheds. Cellar Spiders eat insects and other spiders, but they find ants to be a particularly tasty treat. Like Wolf Spiders, the mother Cellar Spider carries her egg sac around with her, except that she carries it in her jaw rather than attached to her abdomen. Chances are, if you have a house, you have a cellar spider somewhere in the dark corners of your basements, attics, and cellars.
The spider has a pattern on its abdomen, resembling three forward pointing arrows in a lighter color. As its name suggests, the giant house spider, Eratigena atrica, is one of the largest spiders found in Europe and the United States. The species is originally from Europe and was introduced to the Western United States over 100 years ago. It has now developed large populations in the Pacific Northwest and in the Great Lakes area. The giant house spider is the fastest spider in the world with recorded speeds of up to 1.7 ft/s (0.5 m/s).
The pain of agatoxin doesn’t generally last for more than a couple of hours. Each of them goes through the molting phase at least 8-10 times before becoming mature.
Eratigena duellica, the giant house spider, is a species of funnel weaver in the spider family Agelenidae. It is found in Canada, the United States, and Europe.[1][2] The related species Eratigena atrica is also called the giant house spider. The giant house spider is mainly brown with several characteristic markings. The cephalothorax (head) and the legs are a dark, reddish brown with a very dark brown oval shape on its cephalothorax. While they possess venom, it is not potent enough to cause harm. Bites from these spiders are rare and typically only occur when they feel threatened or cornered.
Bites from this creature tend to happen at night or early morning as they’re nocturnal creatures. Eratigena atrica are sometimes found in neglected corners of rooms, on windowsills, and in other enclosed spaces. They build their webs in dark corners of buildings with little interference from other living beings. These sheet-like cobwebs can be so large that they may even connect multiple buildings to each other.
