If you have access to a black walnut tree, you can get rid of fleas in the house by putting the leaves around the edges of each room. My mother was told this by a wise old country woman in Georgia many years ago and it worked for her. Much later, I came back after a long absence to a severe infestation of fleas in my apartment (also in GA). Black walnut leaves did the trick again. I left them long after they had dried up, a couple of months, and then swept them up and tossed them out. The fleas were long gone from both the cats and the apartment by this time and never came back. I've often wondered if the thick green/yellow nut cases (not the shells) would also work, as they have the same strong, staining oil as the leaves, but I've never tried it.
