Brown recluse, black widow and other dangerous spiders found in the U.S.



The world’s deadliest spider’ can help save his own victims

Australian funnel webs are known as the world’s deadliest spider. Now one of their own, Colossus, is milked for its huge production of gif, which will be used to create life-saving antidote against the bite of his own kind.

A black widow found in store bought broccoli to a Tennessee woman who claims that her apartment is infested with dozens of brown recluse spiders, these eight-legged animals found just about everywhere.

Read on for a look at some of the most poisonous spiders found in the United States and what the symptoms appear if you are bitten.

The black widow

Known for the small red hourglass on their abdomen, a black widow’s bite is 15 times stronger than a rattlesnake’s, according to National Geographic.

In the man, “bites produce muscle aches, nausea, and a paralysis of the diaphragm, the breathing is difficult,” says the magazine. Black widow bites can be fatal for young children and the elderly.

According to the Center for Disease Control and Prevention (CDC), black widows are found in the U.S., but they are most common in the southern and western part of the country. You can find them in wood, poles, fences and under leaves, but they can also be found in the “living in outdoor toilets where flies are plentiful,” says the CDC.

Brown recluse

Similar to the black widow, brown recluse spiders also have a distinct marking. These spiders are usually found in Middle-or South — have a “dark violin-shaped (or fiddle-shaped marking on its head,” according to the CDC.

Brown recluse spiders are found in dry, sheltered places, such as under a log or rock. Within the houses, but they usually hide in shoes, closets, attics or garages.


“Brown recluse spider cannot bite humans without some form of counter pressure, for example by unintentional contact that traps the spider against the skin,” the CDC reported, adding that the bite marks typically appear as a “white blister” and can produce localized pain, stinging and injuries.

Fun fact: While most spiders have eight eyes, the brown recluse has six.

Yellow sac spider

Often appears as a yellow, white, or greenish colour, yellow sac spiders account for the majority of the human spider bites. In fact, medical professionals sometimes confuse it with a yellow bag spider bite a brown recluse.

Yellow sac spiders, which are nocturnal, are found almost everywhere in the U.S., according to the University of California in Davis. This spider is known for the “sac” it builds, often found “in the corners of the walls and ceilings, or behind shelves and pictures,” says the university, which also reported that “it can also be seen running on walls and ceilings in the night, and can drop to the floor quickly on a silken thread if disturbed.”

Yellow sac spiders are usually indoors and are known to bite without first being provoked.

“Typical symptoms of a bite include an immediate stinging sensation, followed by redness and slight swelling. Sometimes a blister may form at the site of the bite, often breaking, leaving a sore that heals over a period of several weeks”, according to the University of California in Davis.

That said, it is important to note that this particular arachnid is not to inject its venom every time it bites, and is not to pierce everyone’s skin.

Native to south Africa, this species of spider can be found in the United States, in countries such as Georgia, Florida, North Carolina, South Carolina, Texas, Hawaii, and then, according to the University of Florida.

Like other arancids, the brown widow spider can be found on wooden fences, in hollow trees and under building ledges, among other places.

The most brown widow spiders have an orange-colored hourglass on the abdomen.


In some cases, a brown widow bite can be more severe than that of a black widow. However, according to the University of Florida, these spiders are not particularly aggressive — about 15 percent of the brown widow bites are venomless.

Symptoms of a brown widow bite may include muscle pain and cramps, abdominal pain, difficulty in walking and fever, among other symptoms.
