Can I mix Permethrin SFR 36.8% (about 8 months old) and 10% together?
I have two bottles...one is SFR 36.8 and other one is 10% (about 3 years old). Can I mix them together in an empty dried drinking water jug - gallon size?
It is not recommended to mix Permethrin 36.8% and Permethrin 10% together in a water jug for storage. They should remain in their original containers at room temperature. They have a 3 year shelf life from the date of purchase if stored away from extreme temperatures.
