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. Domestic House spiders are all over North America, as far north as Maritime Canada and as far south as Louisiana. To help avoid Brown Recluse Spiders, don’t leave clothing or shoes on the floor. If you find even one Brown Recluse, contact an exterminator as soon as possible, since this is usually an indication of an infestation. There is no effective antivenom, but if you’ve been bitten, you should obtain medical care immediately.
Common House Spiders – Everything You Need To Know
In hopes of clearing house spiders' name, here are eight interesting facts that might persuade you to put down the shoe, pick up a magnifying glass and give peace a chance. They can easily camouflage near the ceilings of cellars and basements. Cellar spiders can bounce in their webs, which is a defense mechanism they display when threatened or scared. Their ability to leap quickly is the main way these small spiders take down prey. These spiders are typically seen with black bodies and patches of white. Jumping spiders are not considered especially dangerous to humans, especially since they tend to prefer to flee rather than attack.
Grand Canyon Black Tarantula (Aphonopelma marxi)
The brown, biting spiders have a tan to medium brown body with a recognizable violin-shaped marking on their cephalothorax. The black house spider is also related to the gray house spider (Badumna longinqua). This species is slightly smaller and has a pale gray body and legs.
American House Spider Habitats and Habits
The black house spider is identified by its dark gray to black oval abdomen covered in tiny white markings. Also, the spider has a huge leg span of 1.1” (28 mm), making it appear larger. Identifying common house spiders is a great way to ensure you handle them correctly. Although most spiders in homes don’t bite and are not dangerous, there are a few exceptions.

Common House Spiders (With Pictures) – Identification Guide
Their abdomens, however, have v-shaped chevron stripes, and lack their cousin’s distinct longitudinal dark stripes along the head. Domestic House spiders are not a particularly aggressive species, preferring to retreat when confronted. In a home, this can include garages, sheds, barns, basements, and crawlspaces. They’re very solitary spiders, only socializing during copulation. The main sign of a Wolf spider infestation is actually sighting them.
Wolf spiders are furry brown spiders with distinctive black bands on their abdomens. Identifying features of wolf spiders are their eight eyes arranged in three rows, banded furry legs, and a flattened head. The medium-sized brown spiders grow 0.4” to 1.4” (10 – 35 mm) in size.
Jumping spider
Wolf Spiders are usually found on the ground and under stones in a variety of habitats, from woods, fields, and gardens to beaches or even riverbank gravel beds. Looking like something out of a classic horror movie, the orb weaver spider’s web is a circular creation resembling the spoke of a wheel. You typically see them slung between garden plants and in forests. Once unfairly categorized as dangerous, the hobo spider has been since removed from the CDC’s list of poisonous species. Spiders are relatively easy pests to get rid of, says Emma Grace Crumbley, entomologist for Mosquito Squad. Bug experts explain the spiders that like to creep indoors and whether or not their bites can harm you.
The orb-weaver spider measures 0.35” to 0.70” (9 – 18 mm) in length. All spiders have bodies divided into two segments—a cephalothorax (a fused head and thorax) and an abdomen. 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.
American House Spider (Parasteatoda tepidariorum)
The female tarantulas are almost entirely black, while the males are dark brown with some orange or red markings on their abdomens. The Arizona brown spider is a venomous species of recluse spider commonly found in the Grand Canyon State. Also called the desert brown spider, the small light to brown arachnid has a dark violin-shaped marking on its cephalothorax. The brown spider’s body measures 0.35” (9 mm) long, and its leg span is 1” (25 m).
While the Southern House spider’s size can be intimidating, their bite is relatively harmless, and they’re even kept frequently as pets by arachnid enthusiasts. Their bodies are slightly different as well, with longer legs on the males and large, bulbous bodies on the females. Surprisingly, most people living in infested homes, even when the invasion is heavy, don’t report spider bites. In 2001, more than 2,000 Brown Recluse Spiders were found a in a Kansas home, yet the residents had never been bitten, despite living there for years.

Instead, they use their front legs as antennae and hunt small insects. Although technically not classed as a true spider, harvestmen have many of the characteristics of spiders. 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. Pepper Moran is a pest control expert with over five years experience in educating homeowners on affordable and earth-friendly ways to protect their homes from pests. Understanding more about the types and species of spiders you’re dealing with can help with getting rid of them in your home and preventing them from returning.
However, the males look completely different, with slender brown-tan bodies and silvery markings. The most common and largest Arizona spiders are tarantulas, often found in arid desert environments. Common Arizona spiders you can find indoors include brown recluses, black widows, Southern house spiders, and wolf spiders. Brown recluse spiders are a species of venomous house spiders commonly found indoors.
Pictures and descriptions will help to identify the most commonly found Arizona spiders, from tiny cellar spiders to large tarantulas. Besides seeing a spider scurrying across the floor, you can sometimes identify spiders by their web shape. For example, some Arizona spiders have messy, tangled webs, whereas others have irregular, loosely constructed webs.
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. For example, common house spiders and American wolf spiders look similar, but you can tell them apart by the arrangement of their eyes. Another identifying feature of common house spiders is their webs.
When possible, Crumbley advocates for catching spiders and releasing them back outdoors. “The hobo spider can inflict a painful bite that results in localized red swelling and some pain, but no necrotic lesion,” Potzler says. Usually, symptoms will get better within 24 hours with OTC painkillers and ice. Usually, noticing a hobo spider in the home causes panic because there are incredibly agile, swift-moving spiders.
