Deadliest spiders in the world: The world’s most dangerous spiders including the Red-headed Mouse Spider, Six-Eyed Sand Spider and more
Posted On May 6, 2022
And so we come to the most famous of the widow spiders: the black widow, which has gained a reputation as the most venomous spider in North America.
In fact, their venom is about 15 times stronger than rattlesnake venom.
The venom of these eight-legged critters contains a chemical called alpha-latrotoxin, which overwhelm nerve cells and cause immense pain.
The species is responsible for more than 2500 visits to poison control centres every year in the US.
The elderly and children are most at risk from bites.
Thankfully deaths are rare.
The American Association of Poison Control Centres reports no deaths due to black widow spiders since 1983.
The Australian red-back spider is actually a close relative of black widows.
They have their stripe down their back, not their abdomen like black widows, and are less likely to bite humans.
