The gnats you see inside and around buildings are fungus gnats and dark-winged fungus gnats, they are often mistaken for mosquitoes yet they are actually true flies. They can be an annoyance and harm some ornamental plants and garden crops. Most gnats are delicate looking pests with long wings and spindly legs. Generally they are considered to be more of an annoyance and become lively and take to flight during late spring and summer. When plants become overwatered and the soil is not allowed to dry properly, fungus gnats can affect the growth of potted, ornamental, and greenhouse plants. Simply stop overwatering plants to reduce fungus gnat populations, breeding grounds, and kill of infested soil. Light traps can be effective in controlling gnat populations.
