With Permethrin SFR 36.8% for sod webworms, you will mix 0.4 – 0.8 fl. oz. of Permethrin SFR in 4 to 25 gallons of water per 1000 square feet.

We would not recommend adding the Permethrin SFR to your mixture as it is a synthetic pyrethroid just like Talstar. If you are looking to have a little faster knock down you can add the product Kicker which will give you the quick control while the Talstar provides the longer residual. Keep in mind tick control takes time and several re treatments before the population will start to decline. The NyGuard IGR will give about a 4-5 month residual over the reproductive cycle but you can spray the Talstar every 14 days as needed to help knock back the population as well.
