Fruits like grapes, mangoes or oranges highly produce these scents when they are ripening. You will find that more of these flies brood in these environments.

The flowers from various plants also hold breeding grounds for these fruit flies. This is attributed by nectar produced by these particular flowers. In case your compound or yard has these flowers, expect some fruit flies within.

Once the attractants are depleted from the vicinity, these fruit flies looks for any available option around which could be: in your house, nearby hotel or even damping site- just by use of smell.

How does weather change favors existence of fruit flies? 

Fruit flies tend to thrive very well during summer than in winter. This is attributed by the fact that temperature accelerate rotting/fermentation activity, which in turn releases a scent that attracts the fruit flies. Moreover, warm temperature favors breeding of these fruit flies in a given environment.

Fruit flies also work best during dusk or dawn. They like dim light environment more as compared to the bright light areas. This does not mean that you won’t find them in bright-lit regions. No! Only that dim light is more favorable for Fruit flies.

At times, you may even have bought flowers or drinks like wine that attracts these fruit fries. This may attract some of fruit flies to these items without your notice and they end up into your homestead where the further bred.

Where do fruit flies breed/reproduce? 

Now that we know fruit flies are mainly found in hotels, homes or supermarkets where foodstuff are allowed to ferment or rot, let’s elaborate their breeding process. Fruit flies lay eggs near the surface of the rotting/fermenting food, organic material or beneath the fruit skin.

Each fruit fly lay about 500 eggs, which takes 24-48 hours to hatch. This should tell you that within a week, you would expect thousands of these flies in the house if not taken care of.

These flies can also breed in any moist place. It could be drain, garbage disposal, wet rag or mop. The larvae is able to feed on the surface or fermenting/rooting product (fruit/vegetables) thus accelerating the process further.

Contamination caused on food by fruit flies lead to food poisoning. In addition, they introduce bacteria and other disease causing organisms that may be harmful to human beings.
