The Top 10 Deadliest Spiders

Below I have the list of the most dangerous, deadliest, poisonous spiders from around the world.

This list below is the list of the deadliest spiders. If you are looking for a list of the largest and the biggest spiders then check here Top 10 Largest Giant Spiders

  • Banana Spider (Scientific name – Phonenutria nigriventer) – The Banana Spider , with its name may not sound scary to you but it really is. It is very poisonous and ranks for the deadliest spider found in the world. The Banana Spider is found in the Central and South America    

  • Sydney funnelweb (Atrax robustus) – Australia. This is Australia’s deadliest spider which can kill in minutes.

  • Wolf Spider (Scientific name – Lycosa raptorialerythrognatha) – This spider has no connection with a real wolf or it is neither a type of werewolf who can transform into wolf from a spider nor does it look like one. The Wolf Spider has a deadly venom and ranks third in the deadliest spiders found. The Wolf Spider too is found in the same region of the banana spider, in the Central and South America

  • Black Widow (Scientific name – Latrodectus sp.) –  The Black Widow Spider is a very scary spider. It holds its name Black Window as it was believed that the female spider kills the male soon after mating. Anyways, this information is recently been disapproved. It is black in colour. The Black Widow Spider is Widespread all over the World.

  • Violin Spider / Recluse Spider (Scientific name -  Loxesceles recluse)

  • Sac Spider (Scientific name – Cheiracanthium punctorium)

  • Tarantula ( Scientific name – Eurypelma rubropilosum) – The Tarantula even looks very scary and yes, it is too. I guess everyone is familiar to this bred of spider as the tarantula is one of the common venomous spiders found. Tarantulas are found in the Neotropics

  • Tarantula (Scientific name -  Acanthoscurria atrox) – This is another species of the Tarantula which is also poisonous. This too is found in the Neotropics

  • Tarantula (Scientific name -  Lasiodora klugi) – Another poisonous Tarantula, belonging to the same family but a bit different from the rest of them. This spider is found in the Neotropics

  • Tarantula (Scientific name – Pamphobeteus sp.) – This one is a tarantula but is of the other species. This one too is found in the Neotropics

    I would have sworn the deadliest to be the Black widow spider and the Brown recluse spider, how wrong I was. A well researched entry, keep it up.

    No. who told You that?

    The first tarantula is a Brachypelma smithi, the second one is a male Grammostola pulchra (but i’m not sure), the blue one is a Haplopelma lividum (this one lives in Myanmar, and not in the Neotropics), and the last one is a Grammostola rosea. These four species (as well as the other tarantulas) are not deadly.
    The Atrax robustus, Phoneutria nigriventer, Latrodectus hesperus, Loxosceles reclusa or Sicarius hahni are much more dangerous.

    The information in this article is big time bogus. The author has sooo much wrong info it laughable. I challenge anyone reading this article to do a little research and you’ll see just how wrong the info is.

  17. Sadistic Haplo Says...

    On September 13, 2010 at 8:54 pm

    90% of this information is invalid. Yet most of the people believe what it says. I think the author of this article needs to step down from whatever position he has and be forced to do research, opposed to to throwing together an article for the sake of publishing it, and not using any credible information. At points he even mentions that a specific spider(Lasiodora klugi(with an Haplopelma lividum pictured)) is posionous. Disregard anything you have read in this article. It’s all a bunch of garbage put into one heaping compost pile.

  18. Abra Says...

    On September 13, 2010 at 11:17 pm

    One simple search on google would tell you that no tarantula is deadly to a human.

    This is complete BS, and how anyone could believe this vile is beyond me. Wrong information, wrong names.

    The sydney funnelweb will not kill in minutes either, FYI.

    Honestly, how this could even be published in a site called “scienceray” is just disgusting.

    I suggest you, Mr Arrogant, do a bit more research before trying to come of as knowledgeable, because at this very moment, a whole community of arachnid enthusiasts are laughing at your feeble attempt at “playing with the big boys”.

    But I will thank you for providing good entertainment. I haven seen such spiderrelated rubbish since “Arachnophobia”.

    On September 13, 2010 at 11:45 pm

    Not only are tarantulas not deadly, but none of the pictures provided match the species this article claims they are. The number one “deadly” spider on this list is said to be Pamphobeteus, yet the picture is of a Grammostola rosea, the most common tarantula. You can get this “deadly” spider at a petco for less than $20. To the writer of this article, this website itself, and to anyone who believes the crap written in this article, do your research before you post crap like this. This writer did no research at all for this article. For claiming to be a science website, this is a disgrace, but I guess that’s why it’s a .com and not a .org. This article is a laugh and everything in it is crap. To the writer, you fail, you are misinforming people, and you should do research before writing or not write at all. Look for a new career, because this one is getting you nowhere. And to the people reading this, if you want accurate info on the tarantula hobby and see the true nature of tarantulas, please visit DO NOT BELIEVE ANY OF THE CRAP IN THIS ARTICLE THAT IS NOT COMMON SENSE. Looks like the writer put the well known ones like the recluse and widow, and then let his imagination run wild.

    I have got to wonder as a tarantula enthusiast if the article in question was properly researched.Most of the information there in is garbage shame on you sir!Tarantulas and other arachnids are both useful,and fascinating creatures that have an unearned reputation of being malicious killing machines and the perpetuation of these myths is both foolish and unwarranted.

  21. nhdjoseywales Says...

    On September 15, 2010 at 9:11 am

    This article is horribly inaccurate. Tarantulas are not deadly venomous. Most tarantula species have venom as potent as a wasp. None of the species he listed has ever had a single human fatality linked to it, nor has any other tarantula ever. Period. Thanks for playing, you lost. Not to mention this is an exact copy and paste of an article on several other sites, Wrong on all of them.

    The Brazilian Wondering Spider is the most dangerous spider.

  23. M. Brady Says...

    On November 10, 2010 at 5:26 pm

    LIES!!!! lies lies lies!!!! i agree with nhdjoseywales…. i have a Chilean Rose Hair Tarantula, and thier bite is no worse than a bee sting…. The colbalt blue tarantula is not poisonous but is ver agressive, and the mexican red knee is no worse than the rose hair…. and the \”banana spider\” known as the golden Silk spider is absolutely harmless!! the tarantula is more prone to biting humans that that gentle species!!! YOUR ALL BEING DECIEVED!!!! although i will admit that the Wandering spider, black widow, australian white tail, brown recluse and the sac spider are poisonous, the rest are not!!

    P.S. – if im at the age of 17 and know more about these beautiful and misunderstood creatures than the rest of the populas…. thats sad….

    Daddy longlegs venom may be very deadly but they rarely bit and are a very shy and passive spider. Not sure of this but i think this may be the case. Venom very toxic but not a threat as they rarely ever bite anyone.

  27. anonymous2 Says...

    On December 5, 2010 at 9:49 am

    it wwas thought daddy long legs venom was deadly but their fangs too small to penetrate human skin but this has been disproven on the tv show Mythbusters.

  28. Beth Says...

    On January 12, 2011 at 7:52 pm

    Wow. Bad info here. Tarantulas have never killed a human being. Many much more venomous spiders out there. This article was NOT researched well before it was published.

  29. Mark Says...

    On January 12, 2011 at 9:04 pm

    Wow. Certain folk shouldn’t be permitted anywhere near a scientific publication, should they? Seems to me that somebody who has publicly stated they don’t even like spiders should probably not be trying to articulate facts about them, as has been proven by both articles I have read on the subject here.

  30. Stryke Says...

    On January 14, 2011 at 7:31 pm

    Dude, you’re an idiot.
    Do some research.
    Tarantulas aren’t scary, and their venom is not even remotely close to being “deadly”
    There has never been a documented case in history of a tarantula bite killing a human, even the most potent of them has never killed a human.
    Also, if you’re going to post pictures, try to use ones that aren’t of docile species like the Chilean Rosehair , or the Mexican Red Knee, then maybe, and this is a stretch, MAYBE, you might be close to actually telling a hint of the truth!

  31. Sandie Says...

    On January 16, 2011 at 2:34 am

    I’ve never responded to an article before, but this is so badly written that I had to comment. Does anyone proofread or research facts anymore? I guess not.
    In regards to the banana spider, the writer could’ve at least used the correct picture to identify the species. The picture shown is of the banana spider, aka Golden Silk spider, that native to the USA. It is called the banana spider because their colors resemble a banana. This type of spider is not deadly and does not pose a threat to humans. However, the Brazilian wandering spider is also called a banana spider and it’s considered deadly. The Brazilian wandering spider is brown in color. They are called banana spiders because they hitch a ride with the crates of bananas when imported to other countries. I hope people in the US don’t start killing Golden Silk spiders after reading this article!
    On a side note, the black widow is not also called the “Black Window” spider.
    This so-called “writer” needs to go back to school. What a douchebag…

    Some village lost their idiot. You know absolutely jack s***!!!. Most of these spiders are harmless. Where is the Six eyed desert crab spider (Sicariidae Sicarius hahnii) from South Africa?? Very shy spider but very virulent cytotoxic venom, it is considered to be one of the most venomous spiders in the world. Do some research before you put crap like this on the net! Have a nice day..

    To add to the nonfiction group…the Banana spider is not all.

  35. Lou Says...

    On June 17, 2011 at 7:46 pm

    This is all CRAP! tarantulas are not at ALL deadly. Their not even venemous! It only feels like a bee sting when they bite. This guy needs to do some more research before putting all this crap like this on the internet. I even bet you a lot of people believe this!

  36. thissitewastesyourtime Says...

    On June 28, 2011 at 9:01 pm

    FALSE INFORMATION! A simple search anywhere besides this site will immediately indicate how far off this is. Especially for tarantulas. The first tarantula species shown here (brachypelma smithi aka Mexican red knee) is well known for being one of the most gentle of spiders!

  37. Rob Says...

    On June 29, 2011 at 11:47 am

    People really do not listen to any of this guy’s articles he really does not have a clue in ANY of them, I have a very large collection of reptiles and arachnids (Scorpions and spiders) and actually own a lot of what is in this collection of drivel, they are very very few tarantulas that are poisonous and the ones that are dont do us humble humans much harm!

    feels good to correct people without a clue.

  38. Spiderfanatic Says...

    On September 2, 2011 at 5:10 pm

    A tarantula is a type of spider, it is not a species, It merely means a hairy spider. Not only that but they are not all venomous.
    Most of the facts on here are actually incorrect, this is the sort of nonsense causes room and fear that needn\’t be spread. Tarantulas such as the red knee pictured in your post make great pets the only damage they can do is throw hairs at you, they are harmless and are just like cactus spines and are mainly itchy. Spreading such lies are harmful to those such as breeders and fanatics, such lie would put people off of buying the interesting companions thus making breeders useless. so stop.

    Daddy longlegs deadly? Lol no. Their fangs can penetrate human skin and their venom does nothing to us.

    How stupid do you have to be to post an article about spiders without even so much as googling them? Honestly dear, please put your helmet back on and go on outside, the short bus is waiting for you. Seriously, chilean rose hair tarantulas, deadly? They’re neither deadly nor even all that vicious in general. Next time, at the very least, do some research. You just look like a moron.

  44. Callum Evans Says...

    On March 20, 2012 at 4:04 pm

    That’s all lies! Tarantula bites are no more painful than a wasp sting and probably the most deadliest spider is by far the Brazilian Wandering Spider! I have a G.rosea and it’s harmless and the Banana Spider is harmless as well, it’s an orb weaver fgs!

    On May 15, 2012 at 11:06 am

    Wow… Well, pretty much everyone else bashed this article already and I was so looking so forward to it! Well, why stop now? The first photo (labeled Phoneutria nigriventer) shows a completely unrelated Nephila clavipes from the Southeastern USA. If I am wrong, then it is another Nephila species and all of these are completely harmless. Phoneutrias are indeed rather toxic, but still kill far fewer people than cats. Just saying..

    Pic 2 shows god knows what, but at least it looks related to a funnel web and yes, Atrax robustus is arguably the world’s most dangerous spider to humans. That being said, they still kill far fewer people than cats. Just saying..

    Pic 3 shows a wolf spider of some sort, but the Latin name is some made up combination of parts of real names. They are called wolf spiders becuase they wander and hunt for food (the species in the photo is an exception and lives in burrows!). They occur worldwide, even as far North as Greenland and as far South as Tierra del Fuego and none are none to be dangerous to man.

    Pic 4 shows us the Northern Widow (Latrodectus variolus) and actually contains a fact! The male usually leaves safely after mating. The many species are found worldwide in mostly warm climates, though there are two in Canada and a few in Europe (not sure about the temperate South). Despite living in heavily populated areas in some parts of the world, fatalities from widow bites are extremely low and most deaths are actually caused by the use of the antivenom. In other words, you have higher odds of dying from the cure than the bite!

    Pic 5 shows us one of the Loxosceles species, possibly even L. reclusa. These Brown Recluses do have strong venom, and cause some tissue damage (unusual for spiders) almost like a tiny rattlesnake bite. They occur throughout the Southern and Central USA as well as Mexico, Central America and South America. Don’t play with them and they won’t bite you. They are still less dangerous than bees (or cats, just sayin’).

    Pic 6 shows us something I can’t quite identify, but definitely not a Cheiracanthium! Actual Cheiracanthiums (mostly mildei and inclusum) are widespread as they travel in cargo crates and in rare cases can cause painful bites and swelling, though not actually dangerous!

    Pics 7-10 show us four different species of tarantula, none of which are even remotely dangerous (in the only death attributed to a tarantula, the victim died of a bacterial infection at the bite site and even this is dubious as to wether the spider can take the credit, so to speak!). The photos are all incorrectly identified (they are in order, Brachypelma smithi (Mexican Red Knee), possibly Grammostola pulchra (Brazilian Black), Haplopelma lividum (Burmese Cobalt Blue) and Grammostola spatulata or rosea depending on your age (Chilean Rose Hair). Three of these are even very calm and handleable species and of the four Latin names, the first is another creative invention and the other three are also handleable! Please note that this site also has an article on a snake with a human head and hair, so kindly disregard the BS articles!!
    @ M. Brody – The Australian White Tail does not possess a strong venom at all.. The few rare incidents with this spider involve bacterial infections!
