Common House Spider

Head to the ER ASAP if you suspect you’ve been bitten to get immediate treatment. Other names for the brown recluse spider include brown fiddler, violin spider, or fiddleback spider. Although the violin markings on its head are an identifiable feature, other harmless spiders also have similar markings. However, a unique characteristic of the brown spider is that it has six, not eight, eyes like most spiders. The large brown southern house spider has an oval abdomen with a velvety appearance, a shiny brown cephalothorax, and long furry legs. The cellar spider is a harmless, brown spider with a small rounded abdomen and long thin tan-colored legs.

There are also false widows, which look similar to a black widow but are completely harmless. Determine which common house spiders are in your home with this guide. American grass spiders are a type of brown funnel weaver spider with an elongated, oval brown body. Identifying features of the grass spiders are the distinctive dark brown bands running down its cephalothorax, mottled brown abdominal patterns, and spiny, orangey legs. Jumping spiders are identified by their black, tan, or gray bodies with orangish or white markings.

However, it's important to remember that spiders eat insects, including flies and mosquitoes, and they could be keeping these out of the homes they're inhabiting. Spotting a spider in your immediate vicinity can be a little intense, especially if you have a major fear of the creepy crawlers. And with different species come different levels of concern—which makes learning how to identify the critters important.

This small yellow spider has an identifiable egg-shaped abdomen with a pointed end and dark brown markings on its face and the tips of its legs. The small yellow house spider can measure 0.19” to 0.35” (5 – 9 mm) with a leg span up to 1” (25 mm). Many jumping spiders have red or white markings on their abdomens and can be confused for black widows.

A female common house spider can produce several egg sacs in a year. They are very small, papery, brown sacs that hang from the web and can have more than 400 spider eggs inside. The southern house spider is a large dark brown to black spider with a large oval head and elongated fuzzy brown abdomen. Up close, pictures of this house spider show it has dark brown spiny legs and two prominent eyes on top of its head.

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. Since spiders are often found trapped in sinks or tubs, many people assume that's how they got inside. But modern drains feature sediment traps that would prevent spiders from passing, Crawford points out.

Brown widow spiders are typically found in dark, undisturbed areas of your home like behind furniture, basements, attics, or garages. 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. Not everyone who's afraid of spiders hates them, leading many people to try non-lethal eviction.

Can Common House Spiders Bite?

Interior insect monitors are glue traps that can be a valuable tool used to identify and reduce the number of interior hunter spiders in your home. Place them up against the wall or behind dark, damp areas where spiders hide. While bites are rare, they can occur, typically feeling like a small pinch. Though not dangerous, bites can cause pain, swelling, itching, and redness for a few days. When possible, Crumbley advocates for catching spiders and releasing them back outdoors.

Perhaps the most common strategy involves trapping a spider in a cup and releasing it outside, where it can presumably return to its natural lifestyle. This is a noble sentiment (and often requires quick reflexes), but as Crawford explains, it may not achieve the desired result if the arachnid is a true house spider. "They usually spend their entire life cycle in, on or under their native building." Funnel weavers, including the hobo spider, are part of the family Agelenidae and are most noticeable in the fall when their dew-covered webs are visible in the morning hours.

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. Before getting into house spiders that have venomous bites, it's important to understand that more often than not, spiders are not aggressive and do not bite. "In my experience, the majority of household spiders are harmless and prefer to keep to themselves," says Mohamed Samir, pest control senior technician with Bugwise Pest Control. When people find common house spiders, they often destroy the web and kill the spider.

While Russell says these spiders “may bite in defense,” it shouldn’t cause any issues for you. You’ll often find harvestmen in sheds, garages, basements, and crawl spaces. Jumping spiders are usually found near windows and doors as they hunt for small insects to consume. The juvenile spiders hatch within a span of 7 to 10 days after which they gradually disperse.

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. For example, the common house spider and black widow spin cobwebs or tangled webs. 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. Despite this fact, most people cringe at the sight of a common house spider.
