Steinernema feltiae, commonly known as "SF Nematodes," are your garden’s subterranean special forces. While predatory mites patrol the leaves, these microscopic beneficial roundworms hunt in the soil, targeting the larval and pupal stages of pests that use the media as a nursery. They are a high-performance biological solution for breaking the life cycle of Fungus Gnats, Thrips, and the notoriously difficult Root Aphid. Scientific Name: Steinernema feltiae. Best For: Eradicating Fungus Gnats, Western Flower Thrips, Root Aphids, and Shore Flies. Safe For: Plants, humans, pets, and pollinators. Key Feature: Persistence. Once applied to moist soil, they actively swim through the water film on soil particles to track down and eliminate pests.
