An easy to print gnat trap. No support required when placed in the correct orientation. After printing, simply place the tray in the eclosure and fill to about halfway with water and one drop of any dish soap. Then add a few drops of “apple cider vinegar” to attract the gnats to it. The soap breaks the surface tension of the water so that when the gnats step on it to drink, they sink into it instead of standing on top of it as they normally would. You will see a quick reduction in the number of gnats in your home.
