BioBit DF Biological Insecticide contains live spores and endotoxin of a natural bacterium. It acts specifically against caterpillars and does not harm mammals, birds, fish or beneficial insects.
As BioBit DF Biological Insecticide has no contact action it must be eaten by caterpillars and activated in their alkaline gut. Larvae stop feeding soon after ingesting BioBit DF Biological Insecticide, but death and disappearance of treated caterpillars may take several days. BioGro approved.
