Giant House Spiders can reach a leg span of up to 4 inches (10 cm), with their body length averaging between 0.6 to 0.7 inches (15 to 18 mm). Among the largest spider species commonly found in houses, Giant House Spiders are known for their fast speed and large size. Despite their intimidating appearance, they are generally harmless to humans and often contribute to controlling pests in homes by preying on insects. Crawford notes that suspected "wolf spiders" are often just male European house spiders, which tend to roam around more than females do. Although many house spiders weave webs, a few mix things up by actively hunting prey. It's not always easy to tell indoor and outdoor spiders apart, but it might help to study the eyes more than markings or other features.
Harvestmen (Opiliones)
As we’ve already discussed, in the US (and in the UK) most spiders are not venomous. However, to be on the safe side, make sure you wear a pair of thick gardening gloves and long sleeves. If you need to find all (or most) spiders in your home, you should look for telltale signs, such as webs or spider eggs. So, if you have a few harmless spiders in your house, even if they seem to be pretty large, ignoring them can be a reasonable strategy. In the presence of abundant food and the absence of natural predators, the spider population sometimes can grow rapidly. However, spiders usually do not tolerate close proximity to each other, so that’s a limiting factor.
American House Spider Habitats and Habits
This will prevent outdoor living spiders from wandering into your home. If you want to catch a big spider alive, first try to identify the species and make sure it’s harmless. If you’re dealing with a large infestation that you think you can no longer handle, calling a pest control service can put an end to the spider problem.

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. A good place to start looking is our list of top ten pest control companies. The main way to prevent a spider infestation in your home is to make sure they don't have any entry points, like cracks and poorly screened windows or doors.
However, females will sometimes fight when they encounter each other. American House spiders aren’t generally aggressive and have poor vision, preferring to run away rather than engage in confrontation. They only bite humans in self-defense, when grabbed and squeezed, for example, or crushed in clothing or furniture. Desert recluses are brown in color and, as their name implies, are particularly shy. They avoid humans and tend to build their homes in secluded areas like closets and porches. They are also nocturnal, which means they are more active at night.

In addition, some outdoor spiders like orb weavers can make their way indoors and spin intricate webs, creating a spoked, open web to trap insects. Giant house spiders are a very common spider species found in North Carolina. They have a leg span that can reach up to 4 inches, with a brown and hairy body. Their abdomen is patterned with a series of marks, usually lighter than their overall body color.
Hobo Spiders
Maybe not, but ousting spiders from any house is a herculean task. Not only are they stealthy and stubborn, but they've been living with us for a very long time. In fact, many house spiders are now specially adapted to indoor conditions like steady climate, sparse food, and even sparser water. 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.
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. Daddy Longlegs spiders do possess venom sacs, but their venom is very mild and virtually non-toxic to humans.
You’ll often find harvestmen in sheds, garages, basements, and crawl spaces. If you suspect you have been bitten by a brown recluse, ice and elevate the bite while you monitor it. If a bite continues to worsen or you suspect a lesion is forming, consult a doctor for medical care. Don't be too quick to assume that an itchy bump is a spider bite. Spiders would much rather run away from people as opposed to biting them, and spiders are more likely to bite when they feel threatened.
The best bet is to put captured spiders in another manmade structure, like a garage, crawlspace, toolshed, or carport. From spiders the size of dinner plates, to others with inch-long fangs, these mythically-large arachnids roam the earth. Arachnids are handy creatures as they limit the insect population in your home. Therefore, in most cases, the best strategy is to keep the number of spiders under control (instead of completely exterminating them). Double-check everything that’s brought inside from the yard and make sure it’s free of spiders.
The abdomen of the spider is relatively small and lighter, almost yellowish brown and gray, dark brown or black. 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.
"They usually spend their entire life cycle in, on or under their native building." 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.
