Steve, about two years ago I was cleaning the fan blades on our overhead fan in the bedroom. I suddenly noticed that there were these "things" dangling from the spackle coating on the ceiling. My first thought was that they were egg sacks for spiders, because they were defiantely web-like from the look of the threads..turns out they were just discarded webs that the spider who wove it had abandoned. The web, when in active use, lies parallel to the roof, but once they leave the web it basically shrivels and one end falls off, leaving the dangly egg sack looking things.
There were thousands of the things.
I immediately declared war and went "Sadaam Hussain" on them by calling a pest control company. I moved out the family for a few days and chemical warefare commenced.
The spiders in question are tiny...I've probably eaten a bunch if this is a scientific fact that we as humans accidently ingest them. Not any more though.
Just thinking about it gives me the hebie jeebies.
