Other methods for controlling fungus gnats include drenching the soil annually in an insecticidal soap. Hydrogen peroxide can be mixed with water and used to kill fungus gnat larvae in infected soil with a mixture of one part 3% hydrogen peroxide mixed with four parts water, then applied to the soil.

Mycetophilidae is a family of small flies, forming the bulk of those species known as fungus gnats. About 3000 described species are placed in 150 genera, but the true number of species is undoubtedly much higher. They are generally found in the damp habitats favoured by their host fungi and sometimes form dense swarms. [1]
Fungus gnats are a common pest among houseplants.These small flies tend to go unnoticed at first, slowly building their populations by laying eggs on the soil of our container plants.
Keroplatidae is a family of small flies known as fungus gnats.About 950 species are described, but the true number of species is undoubtedly much higher. The long-beaked fungus gnats, formerly placed in a separate family Lygistorrhinidae, have been placed into Keroplatidae as subfamily Lygistorrhininae. [1]
Gnat from Robert Hooke's Micrographia, 1665 A female black fungus gnat. A gnat (/ ˈ n æ t /) is any of many species of tiny flying insects in the dipterid suborder Nematocera, especially those in the families Mycetophilidae, Anisopodidae and Sciaridae. [1] Most often they fly in large numbers, called clouds.
Adult Sciaridae are small, dark flies 1–11 mm long and usually <5 mm long. [4] They have a characteristic wing venation: there is no cross vein except for a short rs at the wing base, the anterior veins are a short R1 and a long R5, vein M has a simple fork with a long stem, and CuA1 has a fork with a short stem.
Most fungus gnats (Sciaroidea excluding Cecidomyiidae) live in forests with their larvae occurring in fungi, dead wood and soil. There are some which live in wetlands such as fens . [ 4 ] Several genera of Sciaridae and Mycetophilidae may reach high abundances in damp buildings with wet organic matter.
