Wasp trap!! 6 oz vinegar, 2 Tbsp sugar, and 1 tsp salt. Mix and put into a container such as a 2 liter bottle that you cut the neck off about 1/4 of the top of bottle and then invert the neck piece so the spout of the bottle is pointed into the bottom half of bottle. This way wasp can crawl in but cant fly back out!!! Or just use a bowl as pictured.
