This may cause people to be sick. Changing the conditions that help flies breed and survive can help eliminate them. The information provided here will help you understand how to identify the flies that bother you, the conditions that make them successful, and some ways to control them. Most insects have four wings, but flies have only two. In place of the second pair of wings are small knob-like structures used for balance.
Many flies have a very short life cycle because they often breed in unstable environments.
If their life cycle was too long, their environment might disappear before they could complete development. They lay their eggs on the surface of fermenting fruit or organic matter. Within two days the eggs hatch and by the end of eight days new adults can be found. Sometimes breeding sites may be difficult to detect, such as with damp mops fermenting due to the presence of food particles or with unrinsed drink cans waiting for recycling. Not very much is known about fungus gnats.
