We have these wolf spiders, and man are they aggressive. They like t build their nests in sand so they like cat boxes. One time my dad went to feed the cat and he noticed something in the cat box and wham, it was trying to jump at him but couldnt get over the side. So my dad used 3/4 of a can of raid to kill it. Ugh!!! Heres a pic of a wolf spider

And no one has ever died of a recluse bite. At least thats what it says in the wiki thing.
