Eye Gnats

Eye gnats are small, shiny black flies approximately 1/16 inch in size. They breed in organically rich soil and are normally found at very low numbers in many parts of San Diego County. To produce their eggs, eye gnats feed on the protein found in body secretions such as mucus from the eyes and nose. In large numbers, they can be an annoyance to both people and animals. Eye gnats are commonly mistaken for fruit flies or fungus gnats.
