Several years ago we had a terrible problem with those nasty bugs - they were all over the outside of the house. You had to be so vigilent whe opening doors and I actually put the blue painters tape around the bottom of the window screens in my room and my sewing room. Our house as those windows that crank open and the screens all seem to have a little bend from being taken out or put back into place over the window handle. We actually mixed the Dawn detergent with water and put it in a lawn sprayer and sprayed the windows, doors and siding. That helped, but then we needed to have some work on the furnace and the guy suggested we get the chimney cleaned, and it's a pretty big chimney cause the house has a fireplace that the previous owner converted to gas, anyway, we had it cleaned and they must have sucked out literally thousands of dead bugs. Since then we have had a lot less of those bugs around. Now we really only see them on extremely hot days. Of course, we are still finding dead ones in boxes in the garages. But never, never, never, squish them--it is proven that the smell of dead stink bugs does bring more. And from all the research we have done on line there is really no product out there that can really kill these bugs.
