Your best bet is asking the manufacturer or retailer.
Guaranteed shelf life on most chemicals is 2 years.
But depending on formula may or may not last longer. Flowables might settle out but chemicals in solution or dry should last longer. You might treat a small area to see if it still works.
Good luck
