You can use PErmethrin SFR in a hose end sprayer as long as it can be calibrated to the required usage rate, though for fleas outside the rate is not set per gallon of water. According to the Permethrin SFR product label: For fleas, ant and ticks in lawns - Mix 0.4 – 0.8 fl. oz. (2.4 - 4.8 tsp) of Permethrin SFR in 4 to 25 gallons of water per 1000 square feet. Use the higher rate for fast knockdown and increased residual control. Dense or excessive (greater than 3 inches) lawn height and arid conditions may require higher volume application rates. Repeat application if necessary. Application in combination with compatible surfactantsor wetting agents may enhance penetration
