Can a spider lay eggs inside a human body?

Spiders, spider's eggs and the like CANNOT survive in the human body. This is one of those urban legends that plays on our fear of spiders. Spiders do not lay their eggs inside of animals (human or other), and the animals (parasites) that CAN survive in the human body, are especially designed to resist the harsh conditions, viz. stomach acid. The larvae of most parasites are encysted to protect against acids and other unfavorable conditions. In fact some wasps lay eggs onto and sometimes into the spider's abdomen. When the larvae hatches, it will eat the spider. Spiders; however, prefer to lay their eggs in the web. Next time you hear a story of someone who had spiders crawling out of the body, take it, with a grain of salt.
