The active ingredient is Bacillus thuringiensis subspecies kurstaki strain SA-12 (Btk). This product affects only the larval (caterpillars) stage of the Lepidoptera order. Once the larvae ingest the Btk, the bacteria work to stop feeding until death occurs. It will not affect birds or beneficial insects (bees, green lacewing, ladybugs, etc.) when used as directed.
