That is supposed to be the lifespan of a gnat, according to http://www.wisegeek.com/how-can-i-get-rid-of-gnats.htm. I’m not so sure. I think I have a four-year-old gnat. For some reason, there is one gnat that flies around my desk. I don’t keep or ever have any food down here. And there is nothing in my trashcan except paper. According to this site, gnats are attracted to food and damp stuff like plant soil. Perfectly logical. Which doesn’t explain what keeps this gnat coming around. The site also says that gnats lay hundreds of eggs in their lifetime and you never have just a gnat. Hmmph. Yes. I have just a gnat. My office is in the finished part of our basement, and is on the opposite end of the house from the kitchen. So, I can’t figure out where it came from, why it’s here and why there is only one. Maybe it’s The Lone Gnat….
