Ready to Know Everything About the Most Threatening  Spiders in The World?

According to statistics, five out of ten people are afraid of spiders and this is one of the most common phobias out there. Scientifically, arachnophobia refers to the intense fear of spiders and can have a major impact on the quality of life. 

Arachnophobia can affect people of all ages and manifests as an intense emotion that can make you feel like you are in real danger. To be honest, in some cases, you could be because some of these spiders can actually be deadly.

The truth is that there are more than 43,000 different species of spiders all over the world, but only a small number can be literally dangerous, while about thirty species are capable of causing human deaths. 

In general, spider venom can be fatal to small animals, but it can also produce severe lesions in humans or cause different allergies. That being said, it’s very important to remember that cases in which people die from spider bites are extremely rare, especially when hospitals and doctors are able to remedy the situation and prevent complications.

In fact, there’s a difference between venom and poison – to be more specific, some species of spiders can be venomous, but never poisonous. So, while most spiders are harmless to humans, here are the most dangerous spiders in the world that could be lethal to humans. Read on to find out more info!

  1. They left off probably the two most dangerous spiders there are: The Brazilian Wandering Spider (or Banana Spider) and the Funnel Web Spider from Australia. Both can cause death to humans.

  2. Yes, OMG, I am sooooo afraid of sppiders and every night before I go to bed, I check out the ceiling, and every other place in my room that I might think one of those icky things may be hiding!!! I hate them more than anything else, or should I say that I am afraid of spiders more than anything else !

    1. Make sure you plug in a ultrasonic sensor with a blue light. Spiders HATE blue lights. They ABSOLUTELY HATE THEM, and will stay away at the sight of them.

  3. Echoing Marc’s comment, I don’t think there’s a deadlier spider on earth than Australia’s Sydney funnelweb spider. If it is fully loaded with venom when it strikes, it can kill a healthy young adult human within 20 minutes, and there is no antivenin. This one is very aggressive and deadlier than the Brazilian wanderer.

  4. Both the Brazilian wondering banana spider and the funnel spider were mentioned and given their due respect

  5. I have always been under the impression that the male Sydney funnel web was the second most dangerous spider in the world next to the Brazilian wandering spider. Why didn’t the funnel web even make the list?

  6. Even the Wolf Spider can trigger Anaphylaxis, which can be deadly for some. It isn’t necessarily the venom or poison, but the individual’s reaction to the toxin.
