Scientific name: Heterorhabditis bacteriophora
Common name:
Entomopathogenic nematodes

Best used: on the larvae of:

Works by: the nematodes will enter the pest larvae and release symbiotic bacteria into the body cavity. This bacteria converts the larval tissue into a food source, on which the nematodes feed, develop and reproduce. The host pest dies within a few hours to days after infection.
