The shelf life for Permethrin SFR 36.8% is 3-5 years from the date of purchase if stored at room temperature. You shoudl only mix up what you are going to use the day you plan to make an application. Any mixed solution left in a sprayer will become ineffective. Always follow the product label for mixing and application rates for the pest(s) you are treating. Not following these guidelines can adversely affect the product and your results.
