Does permethrin SFR expire?
I bought some about a year ago but did not use it all. I need to use it again. Would it still work?
Most all insecticides we sell do not have an expiration date, but most manufacturers place at least a 5 year shelf life on their products. Most can last longer, but the manufacturers recommend you use them within at least 5 years, so your bottle is still plenty good.
