How Dangerous Are Spiders

Spiders

Spiders are arachnids, a class of arthropods that also includes scorpions, mites, and ticks. There are more than 45,000 known species of spiders, found in habitats all over the world. There’s a spider with a cartoonish butt, spiders that can jump on demand, and cannibal spiders that look like pelicans.

Spiders range in size from the tiny Samoan moss spider, which is .011 inch long, to the massive Goliath birdeater, a tarantula with a leg span of almost a foot.

Harmful Spiders?

For most people, the thought of spiders conjures up images of tarantulas, wolf spiders, and other (seemingly) fearsome creatures. Though all spiders have venom to one degree or another, only a handful are dangerous to humans. Those include the black widow and the brown recluse, both found in the United States.

The vast majority of spiders are harmless and serve a critical purpose: controlling insect populations that could otherwise devastate crops. Without spiders to eat pests harmful to agriculture, it’s thought that our food supply would be put at risk.

How Deadly Are Black Widow Spiders?

The black widow spider lives up to its reputation as one of the most dangerous spiders to humans. It is also the most venomous spider in North America. A bite can be painful and debilitating, and often causes pain in your chest or abdomen. Other possible black widow spider bite symptoms include:

  • Headache
  • Anxiety
  • Painful, cramping muscles
  • Numbness
  • Nausea and vomiting
  • Light sensitivity
  • Heavy sweating and salivating

If you have many of these symptoms, you are suffering from what scientists call latrodectism, the illness caused by black widows and related spiders.

How Dangerous Is the Brown Recluse?

The only other spider in North America that poses a medical danger to humans is the brown recluse. If you live in the American Midwest, chances are you live side-by-side with many of these tiny spiders. Even so, your chances of being bitten are slim. That’s because they rarely bite humans.

Although the risk of being bitten is low, these are potentially dangerous spiders. However, no deaths have been reported in the United States. Even if you aren’t killed by the spider, their bites can be extremely painful and scarring.
