According to the Permethrin SFR 36.8% product label, you may spray 4 fl oz to 10 gallons of water. For severe infestation, it is permissible to use 4 fl oz to 4 gallons. When treating poultry directly: Use 1-4 fl oz in 3 3/4 gallons water, which should treat roughly 375 birds. Use 1 gallon of coarse spray per 100 birds." Permethrin SFR 36.8% is only labeled for fly control as a perimeter treatment or for animal quarters such as barns. A more appropriate product would be Talstar P. You should locate and eliminate the breeding source of the flies, since control will be very difficult relying on sprays. An easy and effective tool is the Flies Be Gone Fly Trap, which catches thousands of flies from up to 100 yards away. This trap is disposable and should be hung about 30 feet away from the house or other areas where you spend time. Please see our Flies Pest Guide for more information.
