Gnat problem

While the small size of the gnat can make it appear less serious as a pest, it is important to remember that gnats reproduce quickly and populate infested areas in swarms. The tiny flying insects that many people call "gnats" could really be fruit flies or fungus gnats. Either of these is capable of being a pest and causing damage to the material where it lays its eggs. Most damage caused by these "gnats "occurs during the larval stage, when they are feeding.

Fungus gnats lay their eggs in damp soil of plants that have been over-watered. Leaves, stems and roots are commonly affected in areas infested by these gnats. Growers go to great lengths to prevent and eliminate gnat populations, as the damage caused by a gnat infestation can damage both ornamental and edible plants.

Fruit flies lay their eggs in fruit that is over-ripe or fermenting. They tend to hover near fruit as they are attracted to the scent and moisture of decaying, organic material. Fruit fly females lay their eggs in the fermenting fruit. The larvae eat the fruit when they hatch.  People can become ill from eating fruit that contains fruit fly eggs or larvae.

In order to eliminate a gnat population, their food source must be located and corrected. Fruit should not be exposed to open air. Keeping fruit in the refrigerator protects it from gnats and also prolongs the fruit's period of ripeness. Watering plants only when they need water will help prevent fungus gnat infestations. Contact your local pest control professional if you are encountering difficulty ridding your home of these pests.
