How to Get Rid of Gnats

The most effective means of controlling a gnat population is through preventive measures. In order to control them effectively, it is important to identify the problem correctly. The tiny flying insects that people commonly refer to as "gnats" are usually a species of fly. Two of the most common ones are fruit flies and fungus gnats.  Fungus gnats tend to develop near over-watered houseplants and fruit flies are found hovering over over-ripe fruit or vegetables. Keeping fruit and vegetables in the refrigerator, watering plants only as much as they need and relegating outdoor plants to outdoor areas can prevent gnat infestations from developing.

If you are already experiencing an infestation, there are several commercial products that may assist in controlling their populations. Most traditionally, people use fly swatters to kill individual insects. A number of pesticides and sprays can be used indoors. However, these methods require positive identification of insects, which is best conducted with the assistance of a pest control professional.  Pesticides also require careful application, as they can prove harmful to humans and pets.

Electronic devices that electrocute individual gnats may help to control their populations outside. Inside, insect traps that are plugged into electrical outlets work by emitting ultraviolet light sources. Flying insects are attracted to this light and are caught by the sticky surface of the trap when they approach.

Most of these methods address only individual, adult specimens. In order to properly treat an entire gnat infestation, including larvae, it is best to consult a pest control professional.
