    Hi Ron –

    Safer Garden Dust contains Bt Kurstaki, an effective organic solution for the control of leaf-eating caterpillars. Once applied, it breaks down quickly in sunlight. Therefore, it is recommended that Bt dust be applied in the evening or on cloudy days. Unopened this product will last two years if stored in a cool, dry place. Once opened it will last one year. There is no expiration date on the container.

    Hope this helps!
