Top 10 Dangerous Spiders in the world!

Updated on June 8, 2015

The Hobo Spider

10) The Hobo Spider

No the hobo spider is not a homeless spider and is really no matter to joke about. This aggressive house spider is a European native brought to the United States in the 1980's. The only good thing that I can really say about these little devils is they only attack when provoked. (In other words they wont mess with you if you don't mess with them) A bite from such a little creature will leave you throbbing in pain.

* Fun Fact: An initial study of the hobo spider venom reported their venom to be a medical threat that would produce necrotic lesions. Subsequent research has dispelled this.


Sac Spider

9) Sac Spider

The Sac Spider is one spider by all means people should stay away from. This spider is the most active spider to date when it comes to biting humans. And one bite from this spider will leave you scarred for life potentially as the bite of a Sac Spider has the same effect as a Brown Recluse spider just less severe. Bites from this spider usually tend to get better within a few hours to 1-2 days.

Look at those Fangs on this Goliath Birdeater

8) Goliath Birdeater

The Goliath Birdeater lives up to its name. As the spider is one of the biggest if not the biggest in the world and a part of the tarantula family. If not by length then definitely by sheer mass this is the biggest spider in the world. The Birdeater actually does eat birds when they fly into the super strong web of the spider. When threatened, these spiders rub their abdomen with their hind legs and release hairs that are a severe irritant to the skin. These hairs can be harmful to humans, and the species is considered by some to have the most harmful tarantula urticating hair of all. But to go along with nasty irritating hairs they also pack a nasty bite full of venom. Though the venom is harmless to humans, could you imagine getting bit?

7) Wolf Spider

The Wolf Spider is a hunter, I say this because when they spot there prey they will chase after it a short distance or even hide it out and wait for something to walk past its nest. But just with those two characteristics you can already determine that this spider is aggressive. Wolf Spiders will bite you but only inject venom when continuously provoked. These spiders tend to roam a lot and not sit in one spot for to long and occasionally they will burrow making a trap door to hunt pray. Though these spiders are commonly mistaken for grass spiders, they can be clearly identified by looking at they're eyes. They have 6 small eyes and 2 larger eyes. One other creepy thing about these spiders is they carry they're egg sacks everywhere they go. Once the eggs hatch the babies latch on to the back half of the mama Wolf Spider and stay there until mature enough to leave.

* Fun Fact: The Wolf Spider is the official spider of South Carolina.

6) Redback Spider

The Redback Spider is another dangerous venomous spider located mostly in Australia. The Redback is one of the few spider species that can be seriously harmful to humans, and its preferred habitat has led it to being responsible for the large majority of serious spider bites in Australia. If bit by this spider be ready for pain streaking up and down the effected limb, sweating, vomiting, nausea, headache, and agitation. An anti-venom has been around since the early 1950's. But if bit and not treated the results could be life threatening. Male Spiders and Females can be told apart as female spiders are much bigger then the male. The female has a all black body with a red hourglass shape on it back and an orange and red strip on its front. While the male is about two times smaller then the female.

* Fun Fact: Daddy long leg spiders are known to prey on redback spiders and when great numbers of long legged spiders are around the redbacks are nowhere to be found.

Redback Spiders are creepy looking!

Mouse spiders are muscular looking

5) Mouse Spider

The Mouse Spider seems like a harmless spider with a name like that. But this is another spider that has a powerful bite. Its said that a bite from these large fangs that come from a even larger base cause excruciating pain with the initial bite. Something to be noted is that Mouse Spiders only bite humans and over half the bites are all dry bites. ( Non Venomous)

* Fun Fact: Mouse Spiders are trapdoor spiders, and commonly confused with funnel spiders.

4) Funnel Web Spider

Funnel Web Spiders are of some of the most dangerous spiders. Though they tend to only live for one year dying once cold weather hits. Some have been able to survive two years, but most males die off after mating a few times. It is said that all funnel web spiders are dangerous. A key thing to keep i mind is that the male spiders venom is five times more dangerous then the females due to a chemical called "Robustoxin". Female spiders lack this chemical even though they are bigger they tend to stay in they're burrows guarding they're egg sack.

* Fun Fact: There is actually a relative of funnel web spiders which is a tarantula.

Funnel Web Spiders live in they're funnels!

3) Brazilian Wandering Spider

A spider that looks aggressive in almost every picture on the web as it kicks its front legs up and flashes its bright red fangs. These spiders are absolutely bold as they crawl and run on the jungle floors at night. Though these spiders did not evolve enough to cause significant damage to adults, they can however inflict damage on smaller children. The main thing that makes this spiders so dangerous is day light. Yup, day light is what drives these jungle monsters into hiding, hiding in places such as homes, cloths, boots, and anywhere else light doesn't get to.

* Fun Fact: In 2014 a family in London photographed a living Bazilian Wandering Spider in a box of bananas delivered to they're home.

Black Widow Spiders

2) Black Widow

Black widows are spiders identified by the colored, hourglass-shaped mark on their abdomens. They are found in temperate regions around the world.(Meaning places that are warmer) This spider is so high on the list due to its bite. The venom from a black widow is said to be 15 times stronger then a rattlesnakes in humans, bites produce muscle aches, nausea, and a paralysis of the diaphragm. Luckily fatalities are rare,but when a small child, the elderly, or the sick are effected by the venom. Things tend to take the wrong turn. These spiders are rather to themselves and only bite when provoked by a human. This could include sticking you hand into your old shoe,closet,and any dark area for them to lurk. So stay clear and watch out for these guys.

Some Brown Recluse spiders grow to be over 1 inch long!

1) Brown Recluse

Out of all the spiders in the top ten listing, this is the one to fear the most. The brown recluse spider is not at all aggressive. They tend to live secluded lives always hiding in the shadows. This includes clothing,shoes,folded towels, and many more dark areas you wouldn't look. Bites only occur when a piece of clothing is put on and a recluse is lingering with-in. You may not feel the bite at first. But severe pain is to follow and eventually your skin and tissue around the bite wound up to ten inches around will deteriorate. Not only does that sound horrific but also disgusting. Could you imagine walking around with a 10 in crater of flesh missing.
