I also purchased some of those sticky fly strips that unroll and you hang them, they seem to work for gnats better than the flies so I keep them hanging in my sunroom where I keep all my houseplants for the summer. Never any flies on them which is strange for that's what they are suppose to attract. "HMM" Well at least they are good for something, although they work on flies for my daughter but they have hundreds of flies from all the horses and other animals must have the right smell I guess.
