In concentrate form and in diluted form Thank you!
The Southern Ag Natural Pyrethrin Concentrate has a shelf life of about 2 years at room temperature. Once diluted, the shelf life is the same as any other product and you would want to use the mixed solution within 48 hours as the most. Please let us know if you have any other questions.
