When we cleaned out Keith's in May I vacuumed up the dried remnants of a bug infestation around the windows inside the upstairs bedrooms. Well it seems they're back.
I assume they are hatching out from underneath the shingle siding. It seems to be just this East facing wall which catches the morning sun.
I'm not sure just what the little boogers are. It might be fun to surf the internet and find out.
Update: Well that didn't take long. They appear to be "Box Elder Bugs", also known as "Garage Beetles" and "Stink Bugs", although the name Stink Bugs has been applied to many different bugs.
