I'll have to look those up. I didn't know that there was a box elder beetle. I've only experienced the strong urine-smelling box elder bush, which I had removed immediately after moving in. Thank for a suggestion!
After Googling, alas it is not the boxelder critter. I've seen a couple of them before but never any kind of invasion. The boxelder bug is waaay too big. This bug is solid black.
