A little over a year ago, I made some posts - RIGHT HERE, and HERE - about a long-lived house funnel weaver spider, Tegeneria domestica, that had taken up residence in my basement. It lived for at least nine months, as I recall, but finally kicked the bucket several months back. I know it died, because one day I saw its dessicated husk in the middle of the web.
Well, I left the web stand, sort of to see what might happen. Lest you think me a slovenly housekeeper, I'm not - the upstairs floors are generally neat as a pin. But the basement, well, not so much. Besides, many of your various and sundry creepie-crawlies tend to hide in the dank recesses of basements during the day, and emerge under cover of nightfall. Why not let the spiders remain with them, as they'll only capture the more free-ranging critters that you might like even less.
I'm sure you'll just love that.
