Summary: A proprietary powder containing 10% by weight of spores of bacteria pathogenic for insects has been shown to kill the larvae of the flour moth. In wholemeal flour, between 0.1 and 0.3% by weight of the powder completely prevented the development of infestation by newly‐hatched larvae. Infestations of wholemeal flour in sheds were checked considerably by the application of surface deposits of the spores, established by dusting the dry powder or spraying a suspension in water.
