Like as not, it was a brown recluse. They're all over this house and may have been a factor in the last owners selling at such a reasonable price. I don't mess with Wisconsin spiders. They're all mildly toxic wolf spiders and quite toxic recluses and widows.
I'm thinking of moving as soon as I get a decent job and can afford rent. Because I am no longer in charge of the house that I OWN. I have my parents and my ex-almost fiance living with me and now 2/3 of that group is unemployed and home all day. It is rapidly descending into severe suckage.
