Root-feeding fungus gnats can be especially damaging to plant seedlings, inhibiting growth and transmitting disease. The fungus gnat killer, Stratiolaelaps scimitus (formerly Hypoaspis miles), is a tiny, brown soil mite that feeds on fungus gnat larvae as well as thrips, springtails and other soil-borne larvae.

The adult predator, with its long legs and finely-haired back, punctures the damaging pest larvae and feeds on what’s inside. Tiny and hard-to-spot, S. scimitus inhabits the top layer of soils and prefers moist conditions.
