Save your plants from Sciarid fly/Fungus gnats and larvae damage with our parasitic nematodes Steinernema feltiae.
The adult sciarid flies live on and around the compost surface of pots, more commonly indoors rather than outside. The flies themselves are an unsightly nuisance but most of the damage is caused actually by their young.
The small white larvae live in the compost and feed on the tender roots of plants and cuttings.
Nematodes are more effective if the sciarid population is high. The nematodes are watered on, and attack the sciarid larvae underground. Parasitic nematodes seek out suitable hosts by swimming in the thin film of water on soil particles, locating hosts by detecting carbon dioxide and other waste products. Once they find a host, they enter the body cavity through the mouth, anus or spiracles, and release bacteria (Xenorhabdus). The bacteria kills the host within hours, and the nematodes grow and reproduce within the 'broth', which they produce. The next generation of infective juveniles leaves the dead host, and moves in search of fresh hosts. Infected hosts become brown and flaccid, but once dead can be difficult to find in soil.
