The Most Dangerous Spider Bites & Symptoms To Look Out For

By | source:Here May 10th, 2023

Spiders are some of the most feared animals. Even in the United States, which has an extremely low rate of spider bites compared to other parts of the world, people still suffer from arachnid bites every year. The good news is that spider bites are incredibly rare and only about 1% of all spiders have venom potent enough to cause harm—and even then it’s usually just mild pain or itching. Still, there are a handful that pack a seriously bad punch if they do bite you (or worse). And even though there isn’t much you can do about getting bitten by one of these eight dangerous spiders anyway, knowing their characteristics may help soothe your fears if one ever decides to climb on board with you!

Black Widow

The Black Widow is the most poisonous spider in North America, and it’s found across the continent. It’s also one of the few spiders that can be identified by its red hourglass on its belly. The female black widow has a roundish abdomen with an orange or red hourglass marking on it, while males are smaller and have no markings whatsoever. The venom of this species causes muscle aches and abdominal pains within an hour or two after being bitten by one; nausea may follow later on as well! If you think you’ve been bitten by one of these critters then seek medical attention immediately (or just call us!).


Brown Recluse

Brown recluse spiders are brown in color, with a violin-shaped marking on their cephalothorax. They have six eyes, and the females are usually larger than the males. Their preferred habitat includes undisturbed areas such as attics and basements. Brown recluse bites can be difficult to detect because they’re not always painful at first–and even if you do notice something strange going on with your skin, it may look like an ordinary rash or bite mark rather than a spider bite at all! The symptoms associated with this type of injury include redness around the area where you were bitten (which may progress into blisters), pain that gets worse over time instead of better (as would happen with many other types of wounds), fever or chills within 24 hours after being bitten; itching around affected area(s); nausea/vomiting if bitten near eyes/face area; fatigue (feeling tired). If any of these occur after being bitten by one of these eight-legged creatures then see your doctor immediately!


Noble False Widow

If you think you’ve been bitten by a Noble False Widow, the first thing to do is seek medical attention. The symptoms of their bite are not deadly but can cause severe pain and swelling. They’re most common in southern England, so if you live there or visit regularly it’s worth knowing what to look out for. Noble False Widows are light brown spiders with a dark stripe down their back (known as a “crown”). They are quite small–about 8mm long–so it’s easy to mistake them for other harmless species like house spiders or garden orb weavers which have similar markings.


Six-Eyed Sand Spider

You might not have heard of this spider, but it’s native to southern Europe and North Africa, so you may have seen it before. It can be found in the UK but not in large numbers. The six-eyed sand spider has a bite that is painful but not dangerous; symptoms are similar to a bee sting.


Chilean Recluse

Chilean Recluse spiders are brown and have a violin-shaped marking on the back of their abdomen. These spiders are found in the southern United States, including California, Arizona, New Mexico and Texas. The Chilean recluse is also known as a fiddleback spider because of its violin-shaped marking on the back of its abdomen. Chilean recluse bites cause severe reactions in humans that can lead to death if untreated! They’re one of very few venomous species in North America that can cause necrosis (death) if left untreated for too long after being bitten by one…

As you can see, there are a lot of dangerous spiders out there. The good news is that most bites don’t cause serious harm and can be treated with some ice packs or painkillers. If you’re ever bitten by one of these spiders though (especially if it’s a Black Widow), make sure to seek medical attention immediately!
