We have regular threads on insects and arachnids that cause all kinds of fear and panic. Understandably. Sometimes it's directed at creatures that aren't actually dangerous to us in most cases (like Wolf Spiders). So in order to help educate everyone on the actual really dangerous spiders, here they are to the best of my ability. The list seems to change from year to year, and I consolidated some of them to represent a single spot if they are closely related. The most venomous spiders at the top 5 spot don't change much. Currently Guinness has the Brazilian Wandering Spider at #1, though. But I'd argue it's spot with #2's, as most others would.
Aggressive, and not scared of biting at the first sign of danger. Takes rides on packs of bananas to your home. Check that fruit before purchasing. Very toxic venom, that can cause asphyxiation, causes loss of muscle control and breathing problems, and painful hours long lasting boners. Found in Brazil, or "Brazil? Not going." to some. There is an effective antivenom, and there are few deaths reported. Blow torches may be effective.
Loves your boots, and pools. You can die in 20 minutes of bite. Little to no confirmed deaths from these guys since the early 80's when an antivenom was developed. They have to milk the venom from one of these little, highly aggressive demons 70 times for one dose of antivenom. Found in Nope-strailia (Australia). Avoid at all costs.
Found in North America (shit!). One of the smaller spiders on the list, but still very dangerous and venomous. Like most spiders, loves dark spaces. Venom is neurotoxic.
Another smaller spider, that is once again native to North America. Can be identified by the dark colored "fiddle" shape marking on it's "head", and a light brown to cream colored abdomen. His bite is necrotic. Stay the hell away at all costs. Even treated, the wound will be a gaping hole after a few days. There is no established treatment for necrosis.
Can cause the same kind of necrosis recluse spiders cause. May be the guy biting everyone where the recluse gets blamed in most cases. Small, but again, dangerous. Found in parts of Europe, Australia (of course), Asia and Africa.
There are plenty more, and multiple species related to the ones listed even above.
Don't be like this guy. He's insane, obviously.

2] Funnel-web Spider (Sydney and Northern)
Loves your boots, and pools. You can die in 20 minutes of bite. Little to no confirmed deaths from these guys since the early 80's when an antivenom was developed.

3] Black Widow Spider
Found in North America (shit!). One of the smaller spiders on the list, but still very dangerous and venomous. Like most spiders, loves dark spaces. Venom is neurotoxic.
4] Brown Recluse Spider
