Fruit flies are tiny winged insects that are only 0.2 inches in length. They are brownish in colour, with striped bodies and relatively large red eyes. They can smell food from great distances. Tiny as they are, fruit fl ies can manoeuvre into kitchens through window screens, door jams or any other crack in a home.
They feed on alcohol, which is produced when fruits and vegetables begin to ferment. They not only feed on these foods, but also lay eggs in them that hatch into larvae quickly. In almost the blink of an eye, fruit flies can infest any kitchen.
To eliminate them the food source should be removed. You can also trap them in a paper funnel and place them in a jar or bottle containing a small amount of wine or decaying fruit. They will enter the funnel to reach their feast and will not be able to find their way out.
Although fruit flies are a nuisance to most people, these tiny insects have made a name for themselves in the field of science. Fruit flies, or Drosophilae, have been invaluable to the field of genetics, The short, 10-day lifecycle of the fruit fly, its ability to reproduce and its large chromosomes make the insect an ideal specimen for laboratory experiments in heredity.
