This works....Have a Wasp problem around your porch or deck ? Get yourself a couple brown paper lunch size bags, stuff them with half dozen plastic grocery bags , twist the top and use a twist tie to hang them where they can be seen. Wasp for some reason think it is a hornets nest and avoid it at all cost. I am usually covered in Wasp in the summer living in the woods but since I did this they are few and far between. Mine hang on swing chains each end of the front porch. I have told several people about this trick and they have had the same results.
