The giant house spider feeds primarily on other arthropods, which it hunts at night when they are active. They also tend to feed on flies, moths, and crickets, but some suspect they sometimes eat small birds in the wild too. 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.
How do I get rid of giant house spiders?
They can enter a home on clothing or plants, but are unlikely to establish themselves once in your home. Though an initial study in the late 80s seemed to indicate that their bite was highly venomous, subsequent attempts to reproduce the results failed to produce necrotic lesions. Domestic House spiders rarely produce enough individuals to develop an infestation. One of their possible benefits is that it can out-compete its relative the Hobo Spider, which is venomous.

Giant House Spiders vs. Hobo Spiders
They build webs with a funnel-like hole in the center, where they sit and wait for prey. The giant house spider is not an active climber and indoors can be found on the floor or trapped in sinks and bathtubs where it has ventured in search of water. They prefer to avoid contact with humans and hide during the day, meaning they are most often seen at night.
Common US Spider Families
Normally, bites from the giant house spider involve pain equal to a bee sting. The pain is usually localized and lasts for a matter of hours, or at worse less than 1-2 days. Sealing potential entry points may not affect house spiders, since they don't sneak in from outside, but it could limit incursions by other spiders. And if it also prevents insects from getting inside, it may indirectly reduce your house spiders by limiting their food supply. Various myths suggest house spiders are repelled by osage orange, horse chestnuts, or even copper pennies, but Crawford is doubtful. If you still can't stand house spiders, it is possible to keep them in check without losing your cool.
Eratigena Atrica – Giant House Spider
This venomous brown spider can inflict a painful bite like a bee sting but is not as severe as a black widow bite. Adult male marbled orb-weavers look different from the females because they have an oval, cream-colored abdomen with dark orange and brown zig-zag patterns. Black widows are identified by their shiny black body and distinctive red markings on the underside of the abdomen. The male species can have a black body with red dots and white bands across their bodies. It is important to identify the correct species of spider to tell harmless house spiders apart from ones that bite. The good news is that most spiders you find in your home or garage won’t do any more harm than give you a fright.
If a bite continues to worsen or you suspect a lesion is forming, consult a doctor for medical care. Brown recluse spiders are found most often in the midwestern and southern United States. These spiders are naturally found outdoors in areas where hiding places are readily available, such as debris piles, bark, raked leaves, between or under stones, and within wood piles.
Need help with Giant House Spider control?
Aside from its large size and threatening appearance, this spider does not pose much of a threat to people. Always contact a professional spider exterminator for help with giant house spiders. They are often found in garages or basements, as well as outdoors, in firewood, or in gaps between bricks or stones.
Brown Spiders
The best way to avoid an infestation is by reducing clutter in unused areas of the home, in order to minimize possible hiding places. If spiderwebs are visible, use caution before approaching the area, and if you suspect Black Widow spiders, call a specialist immediately. In a home, this can include garages, sheds, barns, basements, and crawlspaces. Wolf spiders are common throughout all the U.S., but are particularly ubiquitous in Texas, California, and Missouri. They usually invade homes—windows, doors, garages, basements and houseplants—during the fall, in search of warmth.
Some of the most frightening spiders are tarantulas in the Theraphosidae family. A giant house spider is not very difficult to identify, even though there are several very similar species of house spider. Giant house spiders normally remain inside their web during the day since they are actively waiting to pounce on a prey spider or insect that comes close to its web after dark. They can be seen in gardens, backyards, basements, attics, barns, sheds, and any other type of man-made structure. If you want to make sure your house spiders are pulling their weight, check in and under their webs to see what they've been eating.
Bites from this creature tend to happen at night or early morning as they’re nocturnal creatures. The giant house spider is commonly found living in warmer climates where they can (reluctantly) live outside, and prefer to live inside houses and buildings. Giant house spiders are hitchhikers and often make their way into a home by hiding in boxes or belongings. The pests may also come inside through wall cracks and gaps under doors.
The difference in appearance between the adult male and female spiders is that the females are large and have a grayish appearance rather than black. Another distinguishing characteristic of the bold or daring jumper includes fuzzy white hairs covering its black legs. The black and white jumping spider measures 0.25” to 0.75” (6 – 20 mm), and the males are somewhat smaller. Grass spiders are usually found in lawns, parks, and other grassy areas. They have a venomous bite that is fatal for insects but relatively harmless for humans. Because they are another type of beneficial arachnid, it is best to avoid killing them.
Cellar spiders are commonly found in attics, basements, crawl spaces, and undisturbed corners of rooms. You’ll often find the black house spider lurking in wall crevices, crawl spaces, behind baseboards, and window frames. Though Yellow Sac Spiders are venomous, and their venom can cause small lesions in humans.
Common house spiders usually feed on small insects and household pests such as flies, mosquitoes, ants and wasps. They can randomly attack grasshoppers, butterflies, cockroaches or other spiders depending on their size. If the prey is too agile, the spider will try shooting web at it from a distance before pulling the thread toward itself.
It first appeared at U.S. shipping ports in the 1600s, and is now found across most of North America as well as Europe and western Asia. It ranges from 6 to 12 millimeters in length, with a reddish-brown "head" (the cephalothorax) and a pale, speckled abdomen. It builds funnel-shaped webs, and is known to prey on pest insects inside homes. Inside houses, the funnel-webs of giant house spiders are often found in corners on the ground as well as on the ceiling or hidden behind furniture. Since they don’t like to be disturbed by humans, they are most commonly seen in basements or darker areas of houses. Despite this fact, most people cringe at the sight of a common house spider.
If you do get bitten by one, stay calm because it can bite quite hard. Wash the area with soap and water, which will help the wound heal quickly and stop infection from setting in. They may get inside lofts if their entry point is something like a wall cavity or underneath garage doors. It is more likely that they will get into warm warehouses but can also survive in domestic houses if enough heat can be retained during colder periods in winter by opening windows. Actually seeing these spiders in unacceptable numbers is the most obvious sign of an infestation. Normally, these spiders are seen in late summer through early fall when the males emerge from their normal shelters to look for females with which to mate.
