Typically unopened bottles will stay effective for up to 3 years when stored in a cool dry place.
Opened bottles may only last 1-2 years. The rule of thumb on any pesticide - since they don't contain expiration dates - is to use them according to label directions regardless of the age. If at that time, they do not work, then use new pesticide.
Pesticides are like pharmaceuticals, some may last a very long time. We just don't know exactly how long.
