The HB + SC Beneficial Nematode Mix pairs two complementary species — Heterorhabditis bacteriophora (HB) and Steinernema carpocapsae (SC) — in a single easy-dissolve powder, combining their different hunting strategies and soil zone preferences to address a broader range of pest pressure than either species alone.\u003c\/p\u003e\n\u003cp\u003eHB works best against deep-soil grubs and beetles, including Japanese beetles, cucumber beetles, and other ground-dwelling larvae. SC targets pests at or near the soil surface, making it effective against fleas, codling moth larvae, and various caterpillar species. Together, they cover more of the soil profile, giving your garden more complete biological protection. Safe around people, pets, and edible plants. No chemicals, no residue, and no protective equipment required.
