I have had a bag of Arena in my shed for a year. Does it go bad? Meaning I have used it twice this year but I think I'm getting chinch bugs. Does it lose it potency?
Unopened and stored in a temerature controlled environment and out of direct sunlight, a bag of Arena .25 Granules has a shelf life of 3-5 years. Once opened, it’s good for 3 years, as long it is properly stored in the above mentioned conditions. Extreme heat or cold can cause the active ingedient to break down and become ineffective.
