Southern House Spider Vs Brown Recluse

Southern House Spider Vs Brown Recluse. Any spider you discover in your house is referred to as a house spider. In reality, your house probably contains dozens, if not hundreds, of spider species!

The majority of house spiders (and others) are innocuous to people and may be used as indoor insect controllers. Yet, it’s crucial to understand the distinction between a common house spider and the somewhat-risky Brown Recluse.

Southern House Spider vs. Brown Recluse

Because of their color and form, people often mistake the Southern house spider for a brown recluse. The Brown Recluse, on the other hand, has a prominent violin mark and is considerably bigger in size than the Southern House Spider.

It may seem difficult at first to tell the difference between house spiders and brown recluses, but a few simple rules can guide you along the way.

Please keep in mind, however, that unless you are certain of the species, you should never touch any spider or other potentially dangerous animal. If there’s any question, leave the animal alone or contact a professional for help.

Even though the brown recluse is small, it’s still terrifying. Due to its powerful venom and a vast natural range that spans multiple US states, the spider is a well-known safety concern in the United States. States are divided into groups. One of numerous species that are frequently misidentified as recluses is the common house spider (Achaearanea tepidariorum).

Brown Recluses are the male Southern House Spiders. Brown recluse spiders are frequently mistaken for the southern house spider, specifically the male southern house spider.

The male has a physique that resembles that of a brown recluse, owing to its bulk and size. Their behaviors, on the other hand, are very different. The southern house spider and their behaviors, which differ from the brown recluse spider, will be discussed in depth by Eagle Pest Services.

One of the few spiders in the United States that can cause a severe danger to humans is the brown recluse spider, as seen above.

Fiddleback or violin spiders are two names for these spiders. In some cases, their bite may cause painful and deadly sores that may be fatal to individuals. Several homeowners are concerned whenever they come across a spider that they believe might be a brown recluse.



This tip isn’t likely to be useful to you unless you’re close enough to examine for a violin pattern! Yet, when comparing a brown recluse to a house spider or any other species, taking a detailed look at their eyes is the ideal and most certain method to identify it. To do so, you’ll need some magnification!

Brown recluse spiders have just six eyes, as opposed to the typical eight of most spider species. Most spiders have eight eyes arranged in two rows of four, but they have three pairs of eyes, which is unusual.

In addition, identifying a brown recluse versus the majority of other species is difficult since they are one of just a few species with six eyes. This assists you discern the difference between house spider and a brown recluse.

Although each spider species has its own set of characteristics, they all seem to be similar. If homeowners try to identify the kind of spiders they have on their own, it may be difficult for them to do so. Moreover, most people would rather not get that close to these arachnids in order to determine what type they are.

Thankfully, you don’t have to go through this alone. If you want to get rid of spiders, contact a pest management professional instead of attempting it yourself.

These pros have the expertise and training to determine whether you have a southern house spider, brown recluse, wolf spider, or any other sort of spider difficulty on your property. They can provide you with all of your spider and insect control needs.


The bodies and legs of adult brown recluse spiders are roughly the size of a quarter. Their limbs are long and slender, and their skin is usually brown to black in color.

Male southern house spiders have long, slender legs and are likewise light brown. Household pests, such as flies and other insects, are also common prey for both types of spiders.

The brown recluse has shorter legs and is generally smaller than southern house spiders. Their markings and eyes are also distinctive.

A black, slender stripe on the backs of male southern house spiders may be present. In the meantime, the brown recluse has a violin-shaped marking. On adult spiders, this violin- or fiddle-shaped marking is more apparent, whereas on a juvenile brown recluse, it is less apparent.

The next step is to look for the typical violin-shaped pattern on thecephalothorax, or the part of the body where the brown recluse’s legs attach, if you’ve checked and it lives in your region.

As it approaches the spider’s abdomen, a brown recluse spider has a larger patch that widens towards the eyes. On the cephalothorax, a house spider has a uniform color.

While a brown recluse spider does not have a violin-shaped pattern, other spider species do have markings that are similar to the “violin” marking, and it is crucial to note that the “violin” marking alone is not an accurate way of identifying a brown recluse spider.

Brown recluses have distinctive patterns that emphasize their deadly potential to scare away would-be predators, much as the black widow spider, poison dart frog, and other venomous animals.

This mark on the recluse’s head is a violin-shaped patch of black pigmentation just behind the eyes, located on the top of the head.

The violin marking is significantly darker than the surrounding tissue, and the recluse’s corpse is brown. The home spider, on the other hand, has no such distinct markings.

The house spider’s markings seem as flecks or an amorphous black patch of pigment, while the two spiders have a similar body color. According to the NC State University Cooperative Extension, house spiders have black rings on their eight limbs, whereas recluses have uniform coloring.

Brown Recluse spiders keep a low profile around the home, as the name suggests. Spiders are most likely the common household variety if you’re finding them all over.

The majority of house spiders will be tiny and brown. If you can’t find the violin marking on the back, it’s a Brown Recluse.



The bite variations between them should also be taken into account. Humans are seldom bitten by male southern house spiders. Most people, on the other hand, do not have a serious reaction when they do.

Whether it is uncomfortable right away or gradually becomes discomfort, brown recluse spider bites are usually unpleasant. Their venom can also destroy a person’s skin, and their bites often result in painful blisters. This might lead to severe medical disorders in the victim, as well as difficulty sleeping and a fever.


Another good way to compare the differences between house spiders and brown recluses is their overall behavior, especially if you’re not sure about the markings or you can’t bring yourself to get that close to the spider.

Although both spiders spin webs, they do so in distinct locations. You can tell the difference between a house spider and a brown recluse by where the web is located.

Web spiders create their webs haphazardly scattered out from the entrance in a disorganized pattern, with spiders constructing them inside tight spaces. Spider webs are used by house spiders to catch prey and they prefer to stay in or around their crevice.

Brown recluses come out at night to hunt after spending the day hiding under furniture or in closets. Brown recluse webs spin their entire out of sight, and they don’t use them to capture prey, therefore you won’t be able to see them.

The brown recluse spider and the house spider have different preferences for web-building sites. In high places, web spiders build theridiid webs, which are three-dimensional rather than flat nets.

Brown recluses prefer to build their webs in isolated locations behind and below bigger objects, as the name suggests. In basements, inside woodpiles, and in other protected areas, they are often found beneath equipment and furniture.

It’s very unlikely that you’ll encounter a brown recluse web. The mass of lingering “cob webs” along the ceilings of your home and garage is often dominated by spider webbing.

The fact that the southern house spider will build its web in high places, and often in the gaps and seams of homes, garages, and sheds is one of the most prominent behavioral characteristics that separate it from a brown recluse spider.

The brown recluse spider favours to dwell in dark areas. Outside in plants and vegetation, the southern house spider will also spin webs. Their webs are similar to fishing nets in appearance.

The southern house spider webs, on the other hand, are fluffy and entangled their prey, unlike most webs that capture prey via its sticky surface. The southern house spider will retreat during the day in the center of their webs, which has a funnel.

Southern house spiders will store their eggs in her funnel and wait for them to hatch. If the circumstances stay suitable, females might lay up to 200 eggs and may breed all year.

House spiders can live up to eight years and their spiderlings stay together when they are born. They are considered social because they aid and feed one another until they reach adulthood.


Degrees of Toxicity

The amount of danger posed by recluse spiders compared to house spiders is one of the most significant differences for humans. According to the University of Florida IFAS Extension, isolated cases of people dying from spider bite attacks are not a major health risk for humans.

The bite of a brown recluse is significantly more severe. Although the majority of brown recluse spider bites do not cause serious harm to the sufferer, some instances have become life-threatening, especially in children, the elderly, and individuals with compromised immune systems.

While a negative reaction by the victim’s physiology is apparent in visible skin damage surrounding the wound, bites aren’t always instantly painful. Before painful skin damage from venom exposure develops, the bitten region might become itchy or irritated.

Their habitat:

Windowsills, underneath furniture, and hanging out in corners are all common places for house spiders. Brown Recluse spiders favor hiding in more isolated spaces.


Male and female southern house spiders have a striking difference in appearance. Females range in length from half to three-quarters of an inch.

Females have dark patches on their bodies and are charcoal gray in color. When they are pregnant or have recently eaten, their bodies may seem rounded or swollen at the end.

Male southern house spiders, on the other hand, are smaller and slimmer than their female counterparts. They range in length from a quarter of an inch to a little less than a half-inch. They have two appendages in the front that they use to smell and taste, as well as long slender legs. An extra set of legs might appear to be these appendages.

Male southern house spiders have brown stripes behind their eyes and are amber or khaki in color. The males of these spiders have a look and color that are similar to brown recluse spiders, despite the fact that they do not pose a harmful bite. As a result, they’re frequently mistaken for them.

Brown Recluse Range

Seeing if brown recluses even live in your region is the simplest technique to determine the distinction between house spiders and brown recluses before diving into close examinations.

The brown recluse spider’s range is limited, whereas the southern house spider and other spider species have a much larger range.
