I live in Pa. kept my max demon in garage for 3 years. Wondering if it will still work being as it gets darn cold in winter and pretty warm in summer.
Demon Max should be stored in an area that is not exposed to extreme hot or cold. We recommend that you store in a cool, for a three year shelf life from the date of purchase. If mixed with water, it should be used within 24 hrs.
