Many bug bites look alike, but if a venomous spider has bitten you, you may not realize it right away. Many people don't notice insect bites until they react to the venom or the saliva from the creature. Redness, swelling, and itching at the site of the bite are all very common symptoms. If you've been outdoors, or if you've been gathering wood from a stacked pile, you can run the risk of a bite from a venomous spider. In fact, you can even get a spider bite while you're asleep! While all spiders have fangs, and most inject venom into their prey, very few spiders have teeth that can break the skin of a human and cause damage.
Spiders that fall in this risky-to-humans category include black widow, wolf, brown recluse, hobo and camel spiders. Depending on the type of spider that bites you, spider bite symptoms can range from very mild to dangerously poisonous. Some species of spider are limited to certain areas of the globe, while others are more ubiquitous. A brown recluse, for instance, typically won't harm you unless you come into contact with it - and there are precautions that you can take to avoid this. Wolf spiders, on the other hand, are more active and found in just about every part of the world. They prefer grasslands but can make their home anywhere.
