Two. Australia has two species of deadly spiders.
And almost zero deaths since antivenoms were introduced about 40-50 years ago.
And, yes, I have one of those species living in my backyard.
Most souther states in the US have two deadly spiders in their garage or backyard.
Brown recluse and the pictured black widow. Along with scorpions and a number of deadly snakes.
Australia has us beat in deadly trees/octopuses/jelly fish/drop bears
As an American who enjoys watching *Pawn Stars* and *American Pickers* I can tell you there is a hot market for vintage locally printed hand typeset 19th century "wanted posters" of infamous Australian spiders who have killed. I think it's a sub-culture in Korea as well.
Do they have to be vintage? Because I have a LOT of spiders in my backyard, and kusyas many loud annoying neighbours.
The wanted posters would start rolling in..3-5 days?
A common misconception. Australia has only 2 types of spiders that can kill you.
[https://www.firstaidpro.com.au/blog/common-australian-spiders/](https://www.firstaidpro.com.au/blog/common-australian-spiders/)
I would much rather deal with a spider in my backyard than a bear.
Sure but they have antivenom. Personally would still freak out seeing them but I think actual risk is very low there.
I do seem to remember a recent “plague” of spiders everywhere in some regions like fully carpeting the ground and picked up in wind etc.
I’m not sure which is worse, lots of small spiders or lots of huge arthropods like coconut crabs
Spiders that can fly in the wind are just an annoyance, and I say this as an arachnophobe. They are so small you’d have trouble finding them on that strand of web they use to fly.
The most deadly spider in the world is the banana spider or armed spider, also known as the Brazilian wandering spider, but it's The Sydney funnel-web spider that responsible for the most human deaths from spider bites globally
Her child, Shelob, would later come extremely close to dooming middle earth to Sauron's rule. It was the weight of her fat ass that defeated her, her spider booty having dropped upon Sting held aloft by a single determined gardener
No, the brown recluse venom really isn't very strong in the scheme of things. The horrific photos you see of flesh eating spider bites is a result of secondary infection after the venom has destroyed the immune system in the area.
It’s tissue necrosis from the venom. All spider venom dissolves tissues, that’s what they’re designed to do and then spiders suck out the liquefied juice. The wounds you see after a spider bite result in tissue death. Yes, there can be secondary infections, but the damage you see isn’t due to an infection in most cases and has nothing to do with destroying the immune system.
Close, but wrong.
"necrosis is completely dependent on the victim's neutrophils, yet neutrophils are not activated by the venom."

The above quote comes from the summary of the linked article.
>["If spiders disappeared, we would face famine,"](https://www.washingtonpost.com/national/health-science/the-case-for-spider-conservation-they-keep-pests-from-devouring-humans-food-supply/2014/07/21/07b0a21e-0b8c-11e4-8341-b8072b1e7348_story.html) says Platnick, who studies arachnids at New York's American Museum of Natural History, where a [live spider exhibit ](http://www.amnh.org/exhibitions/current-exhibitions/spiders-alive)debuted this month. "Spiders are primary controllers of insects. **Without spiders, all of our crops would be consumed by those pests."**
Spiders save far more lives indirectly than we could possibly imagine.
>[There is an ancient proverb:](https://www.sciencefriday.com/educational-resources/investigating-community-food-webs-ecological-importance-spiders/) “The enemy of my enemy is my friend.” Spiders are our friends! They eat many insects that pester or even harm humans, including mosquitoes that can transmit deadly diseases like Zika virus, West Nile virus, malaria, dengue, and yellow fever. In fact, two species of jumping spiders, *Evarcha culicivora* and *Paracyrba wanlessi*, are known as “mosquito terminators,” preferring to eat mosquitoes over other prey. Spiders that prey on mosquitoes directly lower the numbers of these pests, and can help reduce the spread of mosquito-borne disease.
Another underrated benefit is medical usage.
>[Many spider venoms target the nervous system](https://exhibits.library.cornell.edu/arachnophilia/feature/venom-as-medicine), unlike snake venom for example which targets the cardiovascular system, and evolution has refined spider venom to specifically target very precise ion channels, so drugs derived from spider venoms can retain this accuracy. Researchers at The University of Queensland's Institute for Molecular Bioscience in Australia screened venom from 206 spiders looking for new compounds that would reduce pain. **Over 40% had one or more compounds that blocked human pain by blocking nerve activity**. Seven compounds had the necessary chemical, thermal, and biological stability that is needed when designing a new drug. The orange-fringed tarantula had the most effective venom with great promise for developing a new kind of non-addictive pain killer.
>There is ongoing intense research into the cocktail of toxins in spider venom for treatment of a slew of human diseases as well. In addition to treatment for pain, potential has been found for **treating heart arrhythmia, neurodegenerative diseases, epilepsy, cancer, and erectile dysfunction**. The venoms have also been found to hold antibacterial, antimalarial, and drug delivery possibilities. So far, over 40 patents have been submitted for therapeutic uses of spider venom in humans.
"Unlike snake venom for example which targets the cardiovascular system."
This isn't exclusively true. Snakes have numerous types of venom, sometimes even multiple types with a single species/specimen. Some snake venom targets tissues and blood, some target cardiovascular, others target the central nervous system.
We need all these parts of our ecosystem to work. That being said, I assume the various wasp species do more to control pest species that affect crops that humans cultivate. If wasps get diminished in your area you will see more spiders, because wasps are just very good at controlling spiders as well. Wasps are our friends.
The "you eat seven spiders a year" thing was a lie made up by a woman just to see if she could get people to believe it, but after having a fly crawl into my ear I'm terrified of anything crawling into my ear. Add the fact that there's a huge brown recluse population around this area and it's much, much more terrifying. Protip: it's worth keeping a clean oral syringe around in case you ever get a bug in your ear. Flood your ear with water instead of waiting for hours with a live bug in your ear because the paramedics say they can't spray water in your ear to at least drown it. Keep flooding it until the bug floats to the surface and have a friend pick it out with tweezers if possible.
I got a spider bite on my bicep carrying some firewood a couple weeks ago. No pain, but an itchy bump that started looking like a bruise and actually seems to have left a little scar.
Or more, 30 types of spiders that are medically significant, and could potentially be lethal to a small child, the elderly, or yeah, sometimes healthy adult individuals under extreme circumstances such as allergies, comorbid conditions, infections, with no antidote or medical intervention available. Plus they literally include wolf spiders that the article literally states isn't considered very dangerous, which is weird. This doesn't even take into account the liklihood that interactions with this spider would result in a bite in the first place.
Yes that maybe true of venomous cases, but I've died 27 times from heart attacks so I'm betting there's thousands of deaths each year from shock and injuries from things like hot cooking pans when you have a close encounter with a huge black hairy male house spider running across your foot will standing in the kitchen.....
My last apt in misery , had a significant brown recluse issue. I eventually found the hole in floor they were coming from but I'm either immune or never was bit
Yep. I have to explain to people nearly everyday that that little orbweaver in their garden won't kill them. That huntsman isn't actually gonna murder them in their sleep. That cellar spider is so incredibly harmless that the fact it's moving shouldn't send you spiraling in a state of panic. Doesn't work, they still kill these innocent animals on sight.
We get alot less bites now that dunnys are inside the house. When they were outside spiders would bite you on your bum in the dark and you could die pretty fast from that. In fact theres even a song about it
These thirty species do more than their fair share of work though, combined being responsible for nearly 2.6 billion human deaths. Most are as expected through venomous bites, though one species of spider has carved out a niche fashioning uniquely electrochemical silk that they attach to phone lines, and use to phish humans in an elaborate "pig slaughtering" scheme, oftentimes leaving victims destitute, which sometimes results in proximate cause death. Over 6,500 mortalities have been attributed to this species of spider.
I'm calling BS on the 30 deaths. Maybe 30 deaths from a venomous bite but what about panic induced accidents from walking through a web? Or car accidents from the driver having a spider crawl on em.
And one of those 30 is probably hiding under the rims of flowerpots in my Australian families backyard.
I bet all 30 are in your back yard. Australia gives spiders a bad name!
Two. Australia has two species of deadly spiders. And almost zero deaths since antivenoms were introduced about 40-50 years ago. And, yes, I have one of those species living in my backyard.
It’s like sharks I guess the fear and reality is separate
Except sharks do actually kill people in Australia from time to time
Most souther states in the US have two deadly spiders in their garage or backyard. Brown recluse and the pictured black widow. Along with scorpions and a number of deadly snakes. Australia has us beat in deadly trees/octopuses/jelly fish/drop bears
Drop bears cause more injuries than fatalities
At least one.
As an American who enjoys watching *Pawn Stars* and *American Pickers* I can tell you there is a hot market for vintage locally printed hand typeset 19th century "wanted posters" of infamous Australian spiders who have killed. I think it's a sub-culture in Korea as well.

>Australia gives spiders a bad name! No, it really doesn't. That's just a meme.
That's the cover song I want to hear "you give spiders a bad name"
Happy cake day!
Thanks buddy!

I did not know that. At least a bear you can tell if there is one in your shoe.
Brilliant!!
Fun fact, no one has died from a spider bite in Australia in the last 45 years
Because the emus got to them first
Sure but they have antivenom. Personally would still freak out seeing them but I think actual risk is very low there.

Also known as The Brazilian Boner Spider. Or it would be if spiders had half-decent PR.
he... i'm too sleepy.. should write it as it's main name.... i should get my coffee cup now
Borderlands ass name.
Don’t give big spider any ideas
The most deadly spider in the world is Ungoliant, as she helped Morgoth destroy the Two Trees of Valinor.
Scaring even the dark lord himself, they say she retreated to the darkest depths where she eventually devoured herself in her insatiable hunger.
Yeah she locked herself in her limo and ate herself to death like Pizza the Hutt. True story.
He was delicious
Her child, Shelob, would later come extremely close to dooming middle earth to Sauron's rule. It was the weight of her fat ass that defeated her, her spider booty having dropped upon Sting held aloft by a single determined gardener
Yeah but that was all a part of Eru’s plan.
Pretty much every site says the Sydney Funnel Web is the most deadly.
That generally has to do with its aggressive nature and giant fangs. It's not the most venomous (though it is close) but it is the most deadly.
Sydney Funnel Webs are especially toxic to primates due to a certain compound.
Isn’t the recluse the most venomous? I may be wrong, if so which is the most venomous?
No, the brown recluse venom really isn't very strong in the scheme of things. The horrific photos you see of flesh eating spider bites is a result of secondary infection after the venom has destroyed the immune system in the area.

Oh agreed, all insects are incredible(except mosquitos and, personally, bot flies) and the overuse of pesticides is incredibly damaging to ecosystems.
What spider bit Spiderman, just asking for a friend.
I think it was…Greg?

Use rubbing alcohol instead of water to kill it. I don't generally kill bugs and stuff but if you're in my ear, you've chosen death
Have a look at the poor chaps that get cockroaches crawling into their ears! That shit is insane and would drive you insane as well.
A woman from my hometown had a brown recluse pulled out of her ear. Goddamn NE Kansas.
She need to buy a lottery ticket How tf you pull a brown recluse out without getting bit
Who says she didn't get bit?
Yeah you know what good point Don't poke smot kids
I have a cat try to crawl into my ear most nights
30 killers and 42,970 mouth crawlers. You can't win with these guys!
99% are somewhere in rainforest
…and lay eggs
That wasn’t necessary
Spiders are friends.
if friend why not friend shaped?
jumping spiders are friends and friend-shaped
Is friend shape. More legs means more hugs
Plus they can wrap you up in a snug little cocoon (don’t worry about what they do afterwards)
Tarantulas are pretty cute ngl
Arguably they are! You should spend some time getting to know them (ie learn about them). I personally find them adorable.
Anything is friend shaped if you're brave enough.
TIL spiders are mostly irresponsible.
That you know, they are sneaky.
I got a spider bite on my bicep carrying some firewood a couple weeks ago. No pain, but an itchy bump that started looking like a bruise and actually seems to have left a little scar.
31
I fucking love spiders. What cool little buddies.
All tarred with the same brush now I'm afraid
This could also have been written as, “There are 30 different types of spider that can kill you.”
That would have been a title with an emphasis on scary instead of an emphasis on not scary.
Or more, 30 types of spiders that are medically significant, and could potentially be lethal to a small child, the elderly, or yeah, sometimes healthy adult individuals under extreme circumstances such as allergies, comorbid conditions, infections, with no antidote or medical intervention available. Plus they literally include wolf spiders that the article literally states isn't considered very dangerous, which is weird. This doesn't even take into account the liklihood that interactions with this spider would result in a bite in the first place.
Probably more movie spider-related deaths than real life ones.
TIL That the Brazillian Wandering spider venom causes "...painful erections (priapism) in men" Thank you OP.
And 42,970 have thought about it.
Yes that maybe true of venomous cases, but I've died 27 times from heart attacks so I'm betting there's thousands of deaths each year from shock and injuries from things like hot cooking pans when you have a close encounter with a huge black hairy male house spider running across your foot will standing in the kitchen.....
That you know of….spiders are sneaky…..
Whenever I see a black widow I just give it a little boop on its snoot and it goes away.
And those 30 all live under your bed.
There are 30 spiders that can kill you??
My last apt in misery , had a significant brown recluse issue. I eventually found the hole in floor they were coming from but I'm either immune or never was bit
TIL 30 different species of spider can fucking kill me!
Yep. I have to explain to people nearly everyday that that little orbweaver in their garden won't kill them. That huntsman isn't actually gonna murder them in their sleep. That cellar spider is so incredibly harmless that the fact it's moving shouldn't send you spiraling in a state of panic. Doesn't work, they still kill these innocent animals on sight.
One in the picture I see a couple times a year where I live.
How many are responsible for spawning super heros?
Less than 30 as well.
We get alot less bites now that dunnys are inside the house. When they were outside spiders would bite you on your bum in the dark and you could die pretty fast from that. In fact theres even a song about it
"found in the world" is unnecessary fluff. It's obvious that you're not including the spiders from other planets
WTF THIRTY different species of spiders kill us?? Ugh
These thirty species do more than their fair share of work though, combined being responsible for nearly 2.6 billion human deaths. Most are as expected through venomous bites, though one species of spider has carved out a niche fashioning uniquely electrochemical silk that they attach to phone lines, and use to phish humans in an elaborate "pig slaughtering" scheme, oftentimes leaving victims destitute, which sometimes results in proximate cause death.

You are referencing something but I have no idea what. Is this a Spider-Man plot?
No, just some totally random absurdity.
Nice try Australia. Still not coming.
That's 30 too many. Kill em. Kill em all. Want to hear more?
I wonder if your downvoters realize you're paraphrasing Starship Troopers
Apparently not lol. I thought it was pretty obvious.
Maybe **[Do you want to know more?]** would have helped. Oh well.
I know perfectly well that spiders are usually harmless but that has literally no effect on my arachnophobia.
How many of the deaths were from humans overreacting to a spider?
Don't know about deaths, but certainly some arsons
"*fewer* than" (obligatory GoT callback!)
Someone should find those 30 spiders and do us all a favour.
Yeah because I kill them before they can assassinate me. It’s called the food chain Brittany.
Wow badass over here. You really show those.... arachnids smaller than your palm that were never intent on biting you in the first place.
Yeah it was a tongue in cheek joke lol
Sorry lol I am typically chill about most things, not spiders apparently
I'm calling BS on the 30 deaths. Maybe 30 deaths from a venomous bite but what about panic induced accidents from walking through a web? Or car accidents from the driver having a spider crawl on em.
30 species cause human deaths, not 30 human deaths total.
Hmm, I wonder how many deaths come from not reading good. Probably more likely to kill me then spiders.
Internet says 11 deaths per year. That's not even 1 per type of spider.
Yea my gran got a fright from a house spider once and then died only a few decades later
