Planning to use a dozen cans in probably three years - still work?
There is not a specific expiration date on Wasp-X Wasp and Hornet Spray, but we would recommend using within about 3 years of purchase. You should store this product out of extreme temperatures to ensure it stays stable on the shelf, and be sure you shake well before using. Since this product has a foaming action, you will apply in 1 second bursts, rather than holding down the nozzle for several seconds.
