Parathion-impregnated cords, 3/16″ and 3/32″ in diameter were installed at premises in two separate rural areas of approximately 6 square miles each near Savannah, Georgia. Reductions of house fly populations to low density levels were obtained in both areas for the major portion of the season. Treatment with either size of cord markedly reduced the incidence of flies in kitchens of unscreened residences as compared with those in the untreated zone. The cost of the cord treatment was comparable to that of a standard DDT residual application.
