We, like a lot of other folks, have had stink bugs trying to get in every window or door that is used and some succeed. My trick to removing them, is to use an empty Christmas wrapping paper tube. All you need to do is fold over one end, and use that one for a 'handle' Then you can get those crawling, flying pests; just 'scoop' them up. Some fall to the end you are holding, others you have to give a little pat to the tube. You then can escort them outside or tap the tube on the floor and smash in a bit of paper towel. Sure beats trying to get them with a fly swatter or going after them with a broom.
