Black Widows aren't what I fear. I remember in the eighth grade, our science teacher was bitten by a brown Recluse. I live in Dallas fyi, and we have both the black widow and the brown recluse. Back to my teacher, he was bitten but was unable to identify the spider. Brown Recluses are easy to identify, a violin looking design on the top of their thorax. They also have a weird eye pattern, three pairs of eyes evenly spaced apart. Their bite can be extremely painful if it is not treated or is left unattended. For my teacher, this meant a skin ulcer the size of medium sand dollar. It took almost 8 months to heal, and return to normal. I don't want to scare you too much though, as this case is rare and often the side effects associated with the bites are less severe. Still, I'm going to have to side with Harry Reid on this one NIMBY! ( Not In My Back Yard haha.)
