When we were kids, we used to call these stink bugs. When bothered, they stick their rears in the air and we were always told to stay away from them. When I Googled stink bugs, though, none of them looked like this guy.

They're all over the place here, especially in the garage and under/around the door mats. Is it perhaps in the same family as the stink bug? Any way to control them? We keep stepping on them on the way to the house. :-(
