Calculating the labeled max/yr and my lot size, I figure one bottle would be 4+ years worth.
Celsius should not be stored in a hot garage. Storing chemicals in hot temperatures will degrade the active ingredient and greatly reduce the efficacy of the product. When stored properly, out of extreme temperatures and out of direct sunlight, you can expect Celsius to last for about 3 years from the date of purchase.
