Will milky spore powder impact other insects other than the grub stage of the Japanese beetle? Specifically, will it attack the grub stage of the beetle commonly referred to as a 'fire fly' or 'lightening bug'? Thanks

Paenibacillus popillae the Milky Spore bacterium is applied to turfgrass as a dust. It is effective only in controlling Japanese beetle grubs; it has virtually no activity on other grub species.
