Those of you who are plagued by stink bugs, make one of these traps with a little light in the bottom before you add the top, you push to turn on and at night put in the rooms that they seem to come into the most. Use the 2 liter bottle. You turn the light on and off with a pencil or other long object. Tape the bottle where it overlaps so they cannot crawl out. They are attracted to the light. You can get the lights at the dollar store. Beats the $20 plus at hardware store.
