Can I combine the Permethrin 36.8%, Biffen XTS, and NyGuard IGR? We live in an area that is very affected by Lyme disease, and I want to make sure my family can play out in the yard without having to worry about ticks.
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.
