Heterorhabditis bacteriophora (Hb) is the heavy-duty "Hunter" of the nematode world. While some species wait near the surface for prey to pass by, Hb nematodes are "cruisers" that actively tunnel deep into the soil to hunt down sedentary pests. They are the gold standard for lawn care, specifically targeting the white grubs that destroy grass roots. Unlike chemical grub killers that can harm pets and pollinators, Hb uses a specialized tooth-like structure to break into pests and release symbiotic bacteria, turning the host into a nutrient source.
