7 Most Dangerous, Poisonous Spiders in the World (+Creepy Videos)
7 Most Dangerous, Poisonous Spiders in the World (+Creepy Videos)

Most spiders are feared more because they of their creepiness than because of their ability to inflict lasting harm on humans.

Some of the world’s most dangerous spiders are aggressive and will not hesitate to attack humans with little provocation. Most, however, will cower away and avoid conflict unless cornered—like in a shoe as a foot approaches, or in a shirt sleeve as an arm plunges in.

In the United States, about 60 out of 3,000 spider species are thought to have significantly harmed people.

Here’s a look at seven of the most dangerous spiders around the world.

 

7. Redback Spider, Latrodectus hasselti

Redback Spider

Location: All across Australia. It has spread via exports from Australia to New Zealand. It’s also been spotted across Southeast Asia and Japan.
Body size: Females 0.4 inches (1 centimeter), males 0.1 inches (3 to 4 millimeters)

About 250 people receive antivenom for redback bites each year. About 80 percent of bites have little to no effect, and most of the other 20 percent are painful for about a day but are not serious. The rare serious cases can include symptoms such as rapid heartbeat, headache, vomiting, and insomnia.

No fatalities have been recorded since an antivenom was introduced in the 1950s.

Redbacks don’t stray far from their webs, and most bites have occurred when people came into direct contact with the webs.

 

6. Sydney Funnel-Web Spider, Atrax robustus

Location: Within a 100-mile (160-kilometer) radius of Sydney, Australia. Other species of funnel-web spiders are found throughout Australia.
Body size: Females 1.4 inches (3.5 centimeters), males 1 inch (2.5 centimeters)

Although the Sydney funnel-web spider has not killed anyone since an antivenom was introduced in 1981, it remains “an icon of fear and fascination for Sydneysiders,” according to the Australian Museum. The spider has caused more than 13 recorded deaths. 

The fibers from its web are used in making optical instruments.

These spiders live beneath rocks and logs in forests and also in compost heaps or in the soil beneath houses. They prefer moist, earthy territory.

 

5. Six-Eyed Sand Spider, Sicarius hahni

Location: South Africa
Body size: 0.5 inches (1.5 centimeters)
Size including legs: Up to 2 inches (5 centimeters)

This spider is unique in its ability to camouflage. It not only buries itself in the sand, but even above ground it looks like sand—until you see its crab-like legs scurrying. It has an exoskeleton with bristly hair-like structures that trap sand so the spider is coated in sand at all times.

It rarely bites humans, but its venom is powerful, able to kill a rabbit in a few hours. There are no recorded human fatalities from its bite. Its venom causes blood vessels to leak, tissues to break down, and eventually organ failure.

 

4. Brown Widow, Latrodectus geometricus

Brown Widow

Location: Southern United States
Body size: Females 0.5 inches (1.5 centimeters), males 0.2 inches (6 millimeters)
Size including legs: Females 1.5 inches (4 centimeters), males 0.5 inches (1.25 centimeters)

The brown widow has venom twice as potent as its sister, the black widow. The brown widow does not inject as much venom, however, when it bites. It is a timid spider, and it sticks to secluded, protected areas. Brown widows have been found in outdoor garbage cans, under eaves, in mailboxes, in cluttered garages, under outdoor chairs, and other such places.

    Ick! Ewww! Yuck! Yeow! :-) That being said I have one living in my house…a tarantula named Winston. I’m not fond of having a pet that needs live food (crickets come in the mail..jeeez, the chirping in the house makes it feel like camping), and Winston has completely freaked me out. Who knew that Tarantula’s molted? I screamed like a girl (Ok I am a girl but still…) when I saw TWO massive spiders in the tank. He crawled out of his exoskeleton, and it was left in one complete piece, freakiest thing I’ve ever seen. Oh great, that means he’s still growing. He’s not the cuddliest of pets, but the hubs loves him, so there he is. :-)

    • rg9rts

      Pssssssfty why doesn’t hub do the feeding? I’ll bet you muck that tank too

      • HeyJude

        Good morning, rg! And, Aha! He does…I do not mess with the crickets or muck the tank. :-) But he is a creature in the house, so when I check him during the day, I will refill the water if he needs it. Last week one of the crickets escaped into the house, and I didn’t try to recapture. I couldn’t put him outside, he would freeze. And I figured if the cricket managed to escape being dinner, he earned his freedom. LOL The cat probably ate it. Eeeek.

        • rg9rts

          That was my first thought….out of the frying pan and into the fire. Does hub catch crickets in the summer as a treat???

          • HeyJude

            No need…..what a weird world we live in. You can buy anything online, including crickets. Hub is set up with “Crickets of the Month Club.” (Ok, it’s not really called that) He gets automatic shipments of live crickets. The world has gone mad….. LOL

          • rg9rts

            Keep a close eye on the chocolate sauce!

          • HeyJude

            LOL!!! As much as I love chocolate, I don’t think anything would cover the taste of crickets. But ok, if my “raisinettes” are chirping, I will be sure not to eat them. :-)

          • rg9rts

            I was thinking more him than you… Cynthia is back….had a three day bout with migraine.

          • HeyJude

            Awww, I’m glad she’s back. 3 days? How awful. I’ve had only 2 migraines in my life (you sure know it when you have them) and it is the WORST. Dark room, complete stillness, no noise. Can’t imagine one that long. And, I sure hope Sammy doesn’t read this and get ideas for desert….she tried to serve us Haggis the other day!!!

          • rg9rts

            And sammy is a teatotaler too. I don’t know how they eat that stuff without single malt. Cricket……that’s a brit thing bet she does have something

          • HeyJude

            Hopefully she just plays cricket, not eat them. :-) Hey, I’m a teatotaler, too. Alcohol does not agree with me, even little sips of wine are enough to make my lips go numb and fuzz my head up like I’ve been on an all week binge. There is nothing enjoyable about it for me, darn it. Cause sometimes, you might like a nice glass of wine!

          • rg9rts

            Pretty much on the wagon too.but did enjoy beer and single malt too. This reminds me I really tweaked Hessebalkan yesterday! LOL She and taps ganged up on me with their german heritage and how lovely their baby blue eyes were……….Yeah right. Bloodshot and teary from too much beer…..Hesse almost choked on that one. Laughing.

          • HeyJude

            LOL! And….Hessen is a she??? Arrghhh, here we go again, for some reason I thought she was a he. I will have to create a new mental picture now. I have no baby blues…. green for me, and never bloodshot. :-) How about you?

          • rg9rts

            Hazel..green when happy brown be elsewhere. Hesse is a mommy with children in college. she lives in Macedonia and was rubbing it in about being 70 and spending the evening at the cafe…..She has a good command of english and of course I’ve been teaching her the finer points.

          • HeyJude

            (sigh) I could stand a night in a cafe at 70 degrees about now. I’m cautiously optimistic that our temps are finally going in the right direction. Uh oh, I hope those “finer points” don’t include any of our worst Americanisms. We often butcher the Queen’s English. LOL

          • rg9rts

            50+ this weekend believe it? She was telling me how her kids would show her off color shirts and then laugh at her not understanding them. The English??? Don’t say poof to an Englishman…..

          • HeyJude

            We believe something disappears and goes poof, they believe you’re talking about private gastrointestinal issues. LOL! Yay for the 50’s, we still have SO much snow that needs melting. Sorry this is taking long, dogs are up, out, in, eating, soon to go out again….I feel like a jack in the box popping up to accomodate them. It’s the “puppy’s” birthday today, 1 year old. :-) Little Zeke, he’s a cutie. Of course little Zeke is about 90 lbs now…..catching up to the big dogs everyday.

          • rg9rts

            And poops to match! Monsta is snoring under the covers as usual. Ah the POOF issue…..not a gas issue but rather strikes the homophobe chord in them. I got dressed down by one and couldn’t figure out what I said to insult him.

          • HeyJude

            After I posted, I knew the “other” meaning you were going for….and guessed that was the one you meant. :-) Yeah, I had an issue with dolphins with Gina…apparently it wasn’t the dolphins per se, but my use of the word rendezvous. It’s more than just meeting up to her. An international incident!! Yes….everything is extra large. After the snow melts, the lawn will be a minefield!

          • rg9rts

            Time to put hubs to useful work besides eating crickets!! I’d say put it in the garden but its a little strong. Rendezvous……that has to be a francophobe thing. We learn something new daily

          • HeyJude

            I’ll stick with the horse/sheep mix in the garden…acckk! Yes, she did explain why she was laughing so hard at her assignment. :-) Speaking of work…I can see out my window. All the creatures will be stirring now, waiting for me. Probably a good time to take my leave. We have turned Tara’s very informative spider article into our chatroom! Sorry, Tara, did love the article though! Have a great morning, friend, and will see you later?

          • rg9rts

            TTFN it is getting earlier and earlier for chores YEA

          • HeyJude

            Hugs to Monsta for me. :-) Bye!

          • rg9rts

            In and out today. Got sick after talking to you yesterday and still feel like a tired dishrag.

          • HeyJude

            Oh, no! Sorry to hear it, rg. :-( There is a nasty stomach virus going around, so many are sick with it. If that is what ails you, too, the good news is that it seems to run it’s cycle in 24-48 hours. But no matter what it is…..just rest, eat good soup, drink lots of water, and get to the dr. if you need to. I’ll be back after work this afternoon to check on you, my friend. Get well!

          • rg9rts

            Think I might have sweated it out last night.

            Still tired but am hungry.

          • HeyJude

            Glad to hear it! I just popped in for my last check-in before heading out the door. Take lots of naps, and see if U2 can substitute some nice whole wheat toast instead of the bagel w/ shmeer this morning. :-)
            And later Sammy may have a nice pot of soup simmering over at the pub for you. Monsta is in charge of keeping your neck warm while you nap. See you later! So happy you’re feeling better. :-)

          • rg9rts

            Thats what I had for breakfast. Naps high on the agenda and poking babs to come up with a robin recipe TTFN

    • Denni A

      many, many moons ago when I lived in NYC my significant other had a pet tarantula in a fifty gallon tank, he designed the tank so it looked like a desert with cactus, sand caves for the spider to hide in…etc. I had to pick up crickets at the pet shop.
      when it got mad because I cleaned out it’s tank it would rub it’s back with one of its legs to disburse the hairs on its backside and those hairs itched like hell.

      it’s amazing how they grow out of their old external skeleton and leave it intact while they extract themselves out of it. we would take the old shell out and sit it on a chair for when friends came over to visit…too funny!

      • HeyJude

        LOL! NOW I know what to do with the old shell! :-) What is it with the guys and the tank decorating? Although yours sounds fantastic. My hubs put a mountain landscape picture on the back, so he’d have something to look at (apparently tarantulas “need” atmosphere)…and then it goes eclectic. He has little Roman Columns, an Easter Island Moai head, things to crawl in, rock ledges and little fake trees. Now if you get one in the future, please know you can order crickets on line, delivered to your door. hehehe. Jeez, the crickets need their own cage, and they have to be fed…right up until the time they are chosen for the next meal. I feel bad for the little buggers. :-(

        • Denni A

          LOL!!!… that old shell will create a lot of laughs.
          this was way back in the ’80’s when we had our tarantula. we would put the crickets right in the tank with the tarantula and they would eat good too. we put greens and slices of fruits for them to eat and they would chirp all day and night. you kinda get used to it after a while (chirping) and don’t even pay attention to it, it becomes part of the normal background noise. they (tarantula) can live for 30 yrs. we gave it to a friend when we moved from NY to VA in ’87.

          • HeyJude

            Denni, come back and read…we’ve just hired you. :-)

          • eyelashviper

            A whole line of Spidery Kitchen ware sounds good…itsy bitsy roasting pans for ants, lasagna pans for bug casseroles, and kitchen mitts for all those tiny limbs.

          • HeyJude

            A well appointed kitchen is a must, of course! We will need to run that theme into living room furnishings. I’m thinking a new design for wing chairs….2 arm rests just won’t do. Multi level arm rests, don’t you think? And in the library…fine portraits of inspirational figures. Octopii, centipedes, and the like. :-)

          • Denni A

            hey , I’M READY!!!
            tell me when and where…LOL!!!
            you know that show Tanked(fish tanks) on Animal Planet, we can do one better…”LifeStyles of the Tarantulas”.

            even build a small fish tank inside for the tarantulas to enjoy. probably get in it and eat the fish.

        • eyelashviper

          Your husband has a fine career ahead of him as a hip decorator for tarantulas…maybe even a reality show. It surely would be more interesting that the Faux Housewives and their juvenile hysteria, and the spiders would be so thrilled to see their new digs in the big “Reveal”.

          • HeyJude

            Hi eye! LOL at the big reveal!! Who knew it could be a career path?
            I’ll have to suggest that to him, but I will not be drawn in to sewing little curtains. :-) I suppose he could have a side specialty of halloween decorating…hmm, what would a spider drape on HIS door? Little people in webs I suppose? Ha!

          • eyelashviper

            ahem, they are now called “window treatments”, and of course there will be a “water feature” and stainless steel appliances and walk in closets, a special humidity and temperature controlled cabinet for the crickets, all designed for the finely honed tastes of those multi-legged venemous creatures..
            And the webs with little humans are a nice touch, perhaps an online store to offer such fineries might be a future endeavor???

          • HeyJude

            Ok, forget the husband business…this is sounding fun, we should do it, and drag in Denni down below us, she started it with her desert motif. I wonder if they draped bougainvillea for a southwest feel, are were going more Egyptian with pyramids and such. Stainless steel appliances would include the multi-foot soak tubs I’m assuming? I can’t imagine they need a fridge, as crickets are best eaten “room temp.” :-) Maybe you should design appliances….I’ll start custom framing flies to hang on the walls, and knitting socks (many many socks) as little housewarming gifts.

          • eyelashviper

            LOL, you are on a roll. Should we go on Shark Tank to ask for 7 million in exchange for a 2% stake in our company???
            I like the tiny sox, eight in a box, with various motifs and colors…stripes, polka dots, animal prints, 70’s psychedelic…the possibilities are endless, with matching pairs for the humans.
            Arachnid Fab Fashions ‘R Us…

          • HeyJude

            Love it! LOL! Spiders need flair, too…definitely an underserved population, always ignored by the fashion industry. :-)

  • Haruko Haruhara

    Redbacks are brutal, they are in New Zealand. This article failed to mention hobo spiders,w which are gigantic and poisonous. Not as bad as a black widow or a brown recluse, but still very nasty.

    Article Correction

    Spiders are venomous, they are not poisonous.

    You can if you wished eat the spiders. I know you pride yourself on being a Truthful site, so suggest you correct this erroneous article.

    If you wish people to take your site seriously, be serious about getting the facts correct, the title is so wrong and misleading that it might put people off and secondly educate any children incorrectly.

  • Denni A

    little house spiders don’t bother me at all, I leave them alone and let them catch the mosquitos and flies that get into the house however during the late summer months there are these big garden spiders that come into season, one looks like a zebra with stripes on it and those things freak me out. they ALWAYS build their webs during the night right over the front door entrance to the house and when I open the front door to leave for work in the morning there’s this huge striped spider just hanging there and the whole neighborhood gets to hear me scream…ugh!!

  • allison1050

    The last hospital I worked in I had a young man who had been bitten by a black widow and it was horrible to see what the poor fellow suffered. I’m starting spring cleaning now as a matter of fact!
