Heterorhabditis sp. is a genus of nematodes used in biological pest control, specifically for soil-borne pests. These nematodes are highly effective in controlling white grubs, which are the larvae of various beetles that cause damage to plant roots.
Heterorhabditis nematodes infect and kill white grubs by releasing bacterial symbionts inside the pest, which rapidly kill the host.​
