The first step in conquering a gnat problem is to determine what the gnats are attracted to and remove it or make it unappealing. Locating and removing the gnats' food source is also important.
A gnat is a small winged fly that belongs to the same suborder as mosquitoes. They are characterized by long legs, small bodies and weak flying abilities. Gnats can be biting or nonbiting and may feed on insects, plants or blood. Species include eye gnats, fungus gnats and black gnats.
Some ways to control indoor gnats include placing sand on moist soil, creating vinegar traps, using potato slices to attract the larvae, using sticky traps, and using food-grade diatomaceous earth. Biological controls include using hydrogen peroxide, cinnamon, chamomile tea, Bacillus thuringiensis a
Gnat infestations in the home are typically caused by fungus gnats. These gnats are attracted to moist conditions with organic material. Over-watered house plants, places of condensation and rotting vegetation are the common culprits in gnat infestations.
Gnats eat algae, fungus and various plants. Unlike mosquitoes, they do not consume blood. Some gnats do not eat during their three- to four-week lifespan.

Gnats are small flying insects that are black in color. They have elongated abdomens, transparent wings and long, thin legs. The wing are typically veined but invisible to the human eye. Gnats appear to be almost perfectly round when flying, with few features distinguishable apart from their color.
The most common gnats within a home are fungus gnats, which claim soil from plants as their habitat. Gnats inside a home can also be due to having fruit flies and/or phorid flies.
The best way to kill gnats is to wipe them out in their larval stages by allowing wet soil in house plants and other locations to dry completely. Adult gnats around plants or other areas can be removed using the hose attachment of a vacuum cleaner.
Adult gnats, also known as midges, live for approximately three to five days, following an incubation period of three to seven weeks as larvae and approximately three to five days in the pupa stage. Five generations of gnats can spawn within one summer.
