#6 Brown Recluse Spider
For the most part, the Brown Recluse Spiders are not dangerous because they do not go out of their way to harm anybody, but, you do not want to be the entity that the Brown Recluse Spider is defending itself from. Although most bites from the spider do not cause intense damage, bites from certain spiders can cause necrosis (death of cells) which can take a very long time to heal.
