Please continue reading to learn more about common indoor house spiders. The truth is, you may not know if it's a spider bite unless you saw or caught the spider. Symptoms of red, swelling, and itchy skin are common to many insect bites. If your symptoms worsen or you have a bodywide reaction, contact your healthcare provider.

It's rare to have a life-threatening or fatal reaction from a spider bite, but you may need diagnosis and treatment. Even though a wound left behind by a brown recluse can look pretty serious, brown recluse spiders are much less likely to cause significant injury than black widows. In the United States, black widow spiders, females in particular, are considered the most dangerous. While males may be hard to distinguish from other spiders, females have a unique hourglass shape in a red-orange color on their underside. If you have severe symptoms following a black widow bite, your doctor will administer an antivenin intravenously.
Spider Bite Pictures: Appearance and Emergency Signs
Many people mistakenly believe that long-bodied cellar spiders have venom that would be lethal to humans. However, their venom is not potent and they have no ability to pierce human skin with their jaws, making these spiders harmless pest-eaters. If you have noticed dirty cobwebs in the corners of your walls, they could have been left by a common house spider. These dust-covered cobwebs can easily be vacuumed up or swept down without fear of coming in contact with a spider. Common house spiders choose web locations at random and will readily abandon their web to build one elsewhere if their chosen spot does not result in a meal. Also called the black-footed spider, yellow sac spiders can inflict a painful venomous bite.

Although this small brown spider only measures 0.08” to 0.39” (2 – 10 mm), it has an enormous leg span of 2” (50 mm). In addition, the small spider has six eyes arranged in groups of three. The black house spider is identified by its dark gray to black oval abdomen covered in tiny white markings.
That being said, their bites are not as common as you may think, and they are often harmless. While these pests have venom to subdue their prey, their prey is usually much smaller than people so bites often have little to no effect on us. For most spider species, people are simply too large to be seriously affected. According to the Burke Museum, there are about 50,000 different species of spiders, and of those, only 25 have venom that may cause illness to humans. Widow spiders are not one of the most common types of house spiders, but are the species most people worry about. If you see a spider in your home, it is likely not a widow spider, but it's still a good idea to know what to look for and how to avoid disrupting them.
Black widow spiders are found primarily in the southern and western areas of the U.S., the CDC says. They tend to live in manmade structures, Gangloff-Kaufmann says, like a shed, in the garage or underneath a bench. They're also known to live in outdoor toilets where flies gather, the CDC says. To prevent spider bites while indoors, try to avoid storing items in cool, dark spaces, like under the bed. You can try to avoid spider bites by doing your best to not cross paths with spiders.
Treatment for a nonvenomous spider bite
You will want to get emergency help if you have life threatening symptoms, the bite gets worse, or you have an allergic reaction. Bites from black widow, brown recluse and hobo spiders are more serious. They may cause trouble breathing, a severe headache and painful muscle cramps that require immediate medical care. Even so, deaths from a brown recluse and black widow spider bite are rare. The good news is that most house spider bites are not dangerous.
Though Yellow Sac Spiders are venomous, and their venom can cause small lesions in humans. They may be very painful to begin with, and then develop redness, itching or swelling. Other symptoms may include fever, malaise, muscle cramps, and nausea.
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. Jumping spiders are diurnal, and particularly abundant in grassland and prairie environments, where they prey on small insects. They can enter a home on clothing or plants, but are unlikely to establish themselves once in your home. Hobo spider toxicity is a contested subject among arachnologists. 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. Hobo spiders can often be confused with the Domestic House spider, as they are very similar looking, with the same dark orange or brown coloration, and pale mark on their breastplate.
They tend to stick to secluded, dark areas, like within leaf litter or rock piles. If they go indoors, they might hide in closets, corners or shoes, the CDC says. Some spider venom is toxic to people, however, and can definitely be dangerous.
It moves erratically and actually jumps as a method of moving between locations. You’re likely to find it outside in gardens and near other vegetation. Treatment works best if administered within 24 hours of the bite. Prompt treatment is essential, especially in children and older adults. The Southern House spider is most common in the Southern United States, with some distribution along the Southern West Coast. However, their presence can be lessened by keeping a clean environment.
A fast runner (up to 10 mph), some can grow to over 2 inches long. In severe cases, the bite can result in dead tissue or death. Most tarantula bites in the United States are from pet tarantulas.
To aid with healing, apply an antibiotic ointment three times a day. Spider venom acts differently in humans than bites from a mosquito or flea or a sting from a hornet or bee. Rarely, a bite from a widow spider or recluse spider is deadly, particularly in small children. Seek medical attention immediately if you experience any of these symptoms.
However, the furry house spiders are relatively timid and tend to avoid contact with humans. The black house spider is a robust spider with a dark, charcoal-gray abdomen and white speckles. In addition, the spider has a characteristic velvety blackish-gray body and furry legs.
If provoked, they will bite, and their venom is toxic to humans. The males and juvenile females are smaller, not as black and shiny, and lack a prominent hourglass shape. 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. Harvestmen are easily recognizable by their small round bodies and eight exceedingly long legs.
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. 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. For some people, a small white blister appears soon after the bite, the tissue may become hard, and develop a red, white or blue lesion. In extreme cases, the surrounding tissue can become gangrenous, leaving an open wound as large as a human hand, which can take eight weeks or longer to fully recover. The best way to avoid an infestation is by reducing clutter in unused areas of the home, in order to minimize possible hiding places.
