Just cleaned up the garage and still have that problem near the windows.  Dried up insects from the summer. I believe I got a dustpan full of them. It's annoying. They were everywhere.  In the jamps, on the sill. So, out came the windows again for a hose down and cleaning. Not sure what it is that draws so many of them in the summer. Living in the wooded boonies and farms most likely doesn't help. Windows are clean but I don't want to go through this again? Have to come up with something.
