Hi dsmith813,
I had the same thing in my house that was biting me everyday. I could not see it, only feel it. After a few weeks of getting bit constantly. I tried the following thing: mix a spray bottly with alcohol and vinegar lavenderoil and cedaroil. Spray your entire house with it, especially near your clothes anand kitchen bathroom, and within minutes you will find very small biting gnats that are so small! They died so fast because of the spray. Also burning incence helps a lot. I hope this helps you. Greetz Ranu
