No personal experience ( I smoke a pack a day while out for deer/elk/antelope, I don’t bother trying to cover my scent), but my father in law buys new sprays and wafers every year, regardless of how much is left at the end of the season.

Says he’s reused the previous seasons before, and while it didn’t have an irregular odor (if deer and elk urine has a regular odor to start with) he didn’t feel it worked as well as fresh stuff did.
