Fungus gnats (Sciarids), also called dark-winged fungus gnats, are small, dark, delicate-looking flies that infest soil, potting mixes, container media and sources of organic decomposition. Adult fungus gnats have light gray to clear wings and slender legs with segmented antennae that are longer than their head. Females lay tiny eggs in moist organic debris or potting soil.
Adult fungus gnats don’t damage plants, however, their larvae can damage roots and stunt plant growth. Significant root damage can cause plant death. Serious fungus gnat damage is more common in greenhouses and nurseries than in open fields.
There are specific natural enemies for fungus gnats.
