Shelf life of your bug spray
How long does your bug spray last?
It depends on its ingredients such as DEET. Most brands will tell you to pitch it after three years…but some, such as the Sawyer, claim a ten-year shelf life.
The natural bug sprays tend to lose their effectiveness more quickly, around two years. If the expiration date means anything for insect repellant, it means “it may not work quite as well.”

Sawyer’s spray offers an impressive 12 hours of protection against mosquitoes and ticks, and a little less (eight hours) against flies, gnats, and chiggers.

Sawyer’s Permethrin spray has also worked as promised.

Sawyer, for example, checks to ensure that no pore size exceeds 0.01 microns, stating that “the filters are then checked four more times at crucial points of assembly for filter integrity before they make their way onto the shelf.”
