For example, Bacillus thuringiensis israelensis (BTI) is known to produce proteins that can kill fungus gnats larvae and some other insects like mosquitos. [ 20 ] [ 21 ] [ 22 ] [ 17 ] BTI is a naturally occurring bacteria that has been used for decades—the United States EPA reports that it has no toxicity to humans. [ 20 ]
Sciarid larvae often occur in decaying plant matter such as rotten wood or under the bark of fallen trees, but can also be found in animal feces or fungi. [2] The species Austrosciara termitophila is an inquiline in termite nests while the genus Vulagisciara is a guest in ant-plants of family Rubiaceae . [ 2 ]
In general, gnats go through the four life stages of egg, larva, pupa and adult, [6] similar to other flies. The fungus gnats lay their eggs in moist organic debris or soil, which hatch into larvae. The larvae feed on organic matter such as leaf mold, mulch, compost, grass clippings, root hairs and fungi.
The larvae of fungus gnats live in the soil where they feed on fungi and organic matter, but they also eat plant roots. The larvae are thin maggots, with a shiny black head and long, whitish-to ...

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. [5]
Gnats are attracted to moist areas where they can lay their larvae. This includes any body of water ranging from rivers and lakes to puddles and rain barrels. This creates a connection between ...
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.
