We bought Permethrin SFR 36.8% treat for fleas in our yard, do we water the grass immediately after the application?

Answer:

No, you do not need to water the lawn after applying Permethrin SFR 36.8%  since you are already using 4 to 25 gallons of water every 1,000 sq ft. The water is acting as the carrier – Per the prodcut label Mix 0.4 – 0.8 fl. oz. 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 surfactants or wetting agents may enhance penetration   Permethrin SFR needs to be down for at least 6 hours prior to rain for it to be rainfast but preferably up to 24hrs.
