However, they do tend to become more swollen and red than your general household spider bite, he says. Black widow spiders are tough to identify, as well.

The brown recluse also known as the fiddleback spider or violin spider is one of the most venomous spiders in America, but they are limited to very specific geographic regions—if you don't live in one of these places, it's highly unlikely you need to worry about this type of bite, Vetter says. Check out this map to see if you're in the danger zone. And despite what you may have heard, even where brown recluses are present, they rarely bite, he adds.
To identify a brown recluse, look for six eyes arranged in pairs. Although getting close enough to see the eye pattern on a spider sounds, frankly, terrifying. Brown recluse bites do happen though, and when they do, they are often described by "sharp burning pain," Arnold explains.
Within several hours, the bite area becomes discolored and forms an ulcer that can takes several weeks to heal. In addition to the wound, individuals can also develop fevers, muscle aches, and in rare cases, severe anemia as a result of the venom. Start by treating any bite at home with cold compresses and an antibiotic cream, but if you start to show severe symptoms, including a lot of swelling, increased pain, fever, spreading rash or other sign of infection, get medical attention immediately, he adds.

The hobo spider is actually a pretty common venomous house spider in the U. Forest Service. Male widows, like most spider species, are much smaller and generally less dangerous than the females.
Widows tend to be non-aggressive, but this spider will bite if its web is disturbed or if it feels threatened, especially after laying eggs. The more dangerous female is a dark colored spider with a red hourglass shape on the underside of its abdomen. While the bite feels like a pinprick and at first may go unnoticed or seem rather minor, the black widow spider's venom is reported to be 15 times stronger than that of a rattlesnake. Early on there may be slight swelling and faint red marks.
Within a few hours, though, intense pain and stiffness begin. Other signs and spider bite symptoms include: chills, fever, muscle cramps, and gastrointestinal symptoms such as nausea, vomiting and severe abdominal pain. Typically, black widow bites are less common, but more severe than brown recluse bites. That said, no one in the United States has died from a black widow spider bite in more than 10 years.
The brown recluse spider, also known as the violin spider, is most commonly found in the south-central, mid-western and southern states of the United States.
Most encounters with this spider occur from moving boxes or rooting about in closets, attics, garages or under beds where they may have nested. Brown recluse spiders typically take up residence in dry, warm and dark environments such as basements, woodpiles and closets. These spiders are brown in color with a characteristic dark violin-shaped or fiddle-shaped marking on its head.
Whereas most spiders have eight eyes, brown recluses have six equal-sized eyes. Among these are widow spiders, with about 30 species, and recluse spiders, with more than species worldwide. Typically, a spider bite looks like any other bug bite — a red, inflamed, sometimes itchy or painful bump on your skin — and may even go unnoticed. Harmless spider bites usually don't produce any other symptoms.
Bites from some spiders, such as widow spiders and recluse spiders, might cause serious signs and symptoms. Severe spider bite symptoms occur as a result of the venom that the spider injects. Symptom severity depends on the type of spider, the amount of venom injected and how sensitive your body is to the venom. Risk factors for spider bites include living in areas where spiders live and disturbing their natural habitat.
Widow spiders and recluse spiders like warm climates and dark, dry places. Widow spiders can be found throughout the United States, except Alaska, and are more common in the rural South. They're also found in Europe. They are more active in the warmer months and prefer to live in:. Recluse spiders are found most commonly in the southern half of the United States and in South America, where they are known as brown spiders. These spiders are so named because they like to hide away in undisturbed areas.
