I bought some last fall. Do I need to re-buy? I still have plenty but I wonder if this stuff looses effectivenes
DiPel PRO DF Biological Insecticide will have a three year shelf life if stored away from extreme temperatures and in the original packaging for the most effective control. If you purchased last year, the product should be effective now as long as it has not been wet or obtained moisture during storage.
