Grass-carrier Wasps

I have finally figured out what it is that nests in my windows. The Grass-carrier wasp. Who knew. Check this out. http://www.ipm.iastate.edu/ipm/iiin/node/144 I truly enjoy cleaning my windows each spring. Call me a weirdo, I'm fine with that. But it is so satisfying to look out into our woods through sparkling clean windows. I spent the better part of yesterday doing just that. The kitchen, family room and mudroom are all finished. That only leaves about 10 more rooms and the basement! Every year there are these nests in some of my windows. None of my neighbors have ever seen or had these nests in their windows. I had searched google before trying to determine what these critters were. Perhaps I was not as specific in my search terms because when I searched it again this morning this link came right up. At least I finally know that it is nothing to be concerned about. But how gross. Every year. I almost can't stand it. Here's a post from awhile back that sums it all up.
