So are a nest of brown recluses in the basement.
IF I was to live in St Louis ages ago, me and my ex would have purchased a house with plenty of those in the basement. The prior tenant at the time was an elderly woman that never cleaned up her house and trust me, it needed to be fumigated and such...
Of course, those spiders would have been removed for the obvious reasons before we moved in, but yikes... >.< Removing those and fixing up the house alone would have been almost $30,000. I wonder how much removing snakes would cost.
Luckily for me, that never happened, and I now have a nice clean place in Chicago to call home.
Something else I found interesting... JP Morgan Chase owns the property.... Snakes follow their own, apparently.
