Permethrin SFR 36.8% is mixed at a rate of 1 2/3 fl oz per gallon of water. We also recommend you review our Roach Guide so you can understand how to implement a full roach control program for best efficacy as sprays alone will not eliminate roaches and do not act as a repellents to keep them away.
