Most people hate spiders. They hide in dark corners, creep around, and make webs that get all over your face. If you found a big spider crawling over your shoulder right now, be honest, you’d probably jump out of your seat in fear. Their four pairs of eyes, eight legs, and general ugly appearance makes them freaky creatures. However, when you add venom in the mix, it only makes them that much more terrifying. If you’re an arachnophobe, get ready to squirm. Here are 25 Most Venomous Spiders That Actually Exist.
Noble False Widow
One of the more feared spiders found in England, the Noble False Widow spider is the most venomous of three types of false widow spiders. Its bite causes pain, swelling, nausea, and if it becomes infected, it can lead to gangrene.
Six Eyed Sand Spider
While the Six Eyed Sand Spider is very shy, it’s also known to be incredibly venomous. Because it does not go near humans, there have been few cases of it biting a person. However, in one known case, a man lost his arm from necrosis. If bitten by a Six Eyed Sand Spider, most assume it’ll end in a fatality because there’s no antivenom.
Native to New Zealand, the Katipo spider is endangered. Only the female is capable of biting a person, but their bite isn’t thought to be lethal but rather unpleasant. By “unpleasant” we include symptoms like abdominal cramping, sweating, fever, and shaking.
Brown Recluse Spider
Brown Recluse Spiders are considered the most venomous spider in the United States. If bitten, victims could experience fever, convulsions, itching, nausea, and muscle pain. In extreme cases, they could also experience necrosis (death of skin tissue).
Hobo Spiders were originally thought to cause horrible lesions if a human was bitten, but recent studies have dispelled this notion. While they are not considered medically threatening, their venom can cause, redness, swelling, and twitching for several hours.
Despite their intimidating appearance, tarantula venom only creates a painful bite and the hairs on their legs can cause skin irritation. Unless someone happens to be allergic, it’s not harmful to humans.
The Cupboard Spider isn’t known to be dangerous to humans. For most people, their reactions to venom are similar to a wasp sting. However, there have been a few cases where more serious symptoms were recorded.
The Redback Spider’s bite is not only painful, but will also lead to certain death if not treated immediately. An anti-venom was created in 1956. 250 people a year receive this anti-venom.
Black House Spiders
A Black House Spider’s bite is poisonous but not deadly. However, it can cause severe pain, swelling, nausea, and vomiting, among other horrible symptoms.
Black Widow Spider
Black Widow Spider’s venom is about 15 times as toxic as the prairie rattlesnake. However, only the female can harm humans. The females usually have a red hourglass on their abdomen.
Yellow Sac Spider
The Yellow Sac Spider’s bite may cause severe pain with symptoms like fever, muscle cramps, and nausea, but rarely does it become a severe medical condition.
Recently discovered in Sri Lanka, the Poecilotheria Rajaei spider is a type of tarantula. It has enough venom to kill mice, lizards, and small birds.
Sydney Funnel Web Spider
Native to Australia, the Sydney Funnel Web Spider can kill you within fifteen minutes of its bite. Luckily, there is an anti-venom…if treated quickly enough.
Trapdoor Spiders are often mistaken for Funnel Web Spiders, but they rarely bite and if they do, it’s low risk to humans. It can, however, be quite painful.
Brown Widow Spider
In most cases, the Brown Widow Spider’s bite only causes minor problems but occasionally they can be serious, including muscle spasms, headache, and nausea.
Most male and female Mouse Spiders have very large fangs and are also aggressive. Fortunately, only certain species have been found to cause serious symptoms.
Chilean Recluse Spider
While death resulting from their bites is very uncommon, the Chilean Recluse Spider can cause serious symptoms such as skin irritation and death of skin cells.
With a name like “Wolf Spider,” it would make sense for people to be afraid of it. However, its bite isn’t deadly and only causes minor irritation. However, some victims may be allergic and will need to seek medical attention.
Northern Tree Funnel Spider
A relative of the Australian Funnel Web Spider, the Northern Tree Funnel Spider is just as deadly and dangerous. Unlike their relatives, they live mostly in trees and wooded areas.
Red Widow Spider
Found primarily in Florida, the Red Widow Spider can cause spasms in humans if bitten. Luckily, there aren’t many recorded bites as they don’t often come into contact with humans.
Tiger Wandering Spider
The Tiger Wandering Spider is similar to the Brazillian Wandering Spider. It has a complex neurotoxic venom and is known to cause severe pain among other symptoms upon biting.
Corner Funnel Weaver Spider
While rare, a bite from a Croner Funnel Weaver Spider has had cases of severe headaches and vomiting.
Found in Africa, the Baboon Spider is very similar to a tarantula. A bite from a Baboon Spider could lead to vomiting, difficulty walking, and shock.
Lynx Spiders are known to have a jumping mechanism and are also one of the few spiders that can actually spit their venom. While they aren’t deadly to humans, their venom can cause localized swelling up to 10 inches (25 cm) in diameter.
Yes, we said they can spit their venom. *shiver*
Brazilian Wandering Spider
When Guinness Book of World Records claims the Brazillian Wandering Spider, also known as the Banana Spider, is the most venomous spider in the world, you definitely don’t want to mess with them. Fortunately, they’re only found in tropical climates in the Caribbean and South America.
