There are over 40,000 identified species of spider in the world, 3,000 of which are found in the U.S. and thousands more yet to be discovered. While almost all spiders have poison glands, most of them don’t actually bite without provocation.
Spider bites are uncommon, and they usually happen after the spider has been squeezed, surprised, injured or trapped. When spiders do attack, their bites are generally harmless, as only a few types of spiders have fangs strong enough to pierce human skin and insert venom.
However, this doesn’t mean that you should just ignore a spider bite, as some may lead to severe symptoms and, in rare cases, death. Read on to find out how to identify the different types of spider bites and what to do in case you’re bitten.
