Two insecticides like Permethrin SFR 36.8% and Bifen XTS should not be mixed together. Creating a pesticide mixture that is too string can backfire, causing insects to avoid the treated ares. However, NyGuard IGR can be mixed with either of these alone.
Permethrin SFR 36.8% is applieid at 0.4-0.8 fl oz to 4-25 gallons of water per 1,000 sq ft for applications to lawns for ticks.
Permethrin SFR 36.8% can be applied to turf, trees and ornamentals for effective insect control. It can be sprayed into or onto damage caused by boring insects,but it is not labeled for injecting or soil drenching as an application for live trees. Always refer to the product label for the correct mix ratios and application rates.
We would recommend using hot soapy water with a mild detergent to remove any unwanted residue.
You can also help by creating a "tick safe zone" in your yard. You should have an area that is at least 9 ft wide between your yard and any wooded area. Trim back trees to allow as much sunlight as possible into your yard. Keep grass as short. Remove as much leaf litter as possible. A clearly defined, well manicured border between your yard and any wooded areas or weedy lots will reduce the chance of ticks infesting your yard.
