Ok I live here in south Alabama and am some serious problem with the small gnats. I am going to try a few things and let you guys know how they work. I'm starting with, Hi-Yield brand Garden, Pet and Livestock Dust. Will be dusting the brooder, chick pin and all of the 4 week old chicks. Not going to put a whole lot on the babies. Just a light dusting. Will let you know how things go.
