Drosophila: identification

Drosophilas are tiny but highly unpleasant neighbors in the kitchen. An adult one is about 1/8 long, but you rarely see one alone. It almost always moves in a huge company. These red-eye insects have an incredible ability to smell food that is about to spoil at great distances. Rotting fruits are vital to them, and their entire body is tuned to catch the subtlest smell emitted by overripe vegetables and fruits, which a person may not even feel. It would be helpful primarily to protect fruit from fruit flies. But fruit is not the only thing that might tempt them to make its way to your home. Here is a far from the complete list of objects that might attract drosophilas:

  • Ripe fruits and vegetables, especially bananas;
  • Leftover food and waste;
  • Dirty containers, especially from beer and wine;
  • Pet food;
  • Sewerage;
  • Garbage containers;
  • Mops and rags for cleaning;
  • Moist soil of vases with flowers.

One female can lay about 500 eggs, turning into adults in almost a week. For this, it needs only moist organic materials in the fermentation stage. If you do not avoid fruit flies at home, they will live in your kitchen for about a month.

How fruit flies get into the house

These pests might not only be intrusive but contaminate food with bacteria and other disease-causing organisms. They may choose your kitchen as their target, sensing that a fruit plate or trash can has been there since last night. Drosophila can fly in from the outside through poorly closed windows and doors. Infection might occur through overripe fruits or vegetables previously infected and brought at home. In addition, the eggs of these insects might get into the house with the fur of pets and on shoes.

Fruit fly prevention: look around

If you want to say goodbye to drosophila, you should think like drosophila. Imagine where you could have a delicious meal if you were a fly. Where would you be cozy? Then conduct an audit and do everything not to leave them the opportunity to eat and reproduce. First of all, protect fruit from fruit flies. It is essential to keep clean in all areas and stick to the following recommendations.


  • Regularly go through stocks of products, and throw away those that have begun to spoil;
  • Store loose products in moisture-proof containers and check cereals for flies;
  • Store all perishable products in the refrigerator;
  • Wash and dry the bread box before laying each new one.


  • Do not leave dirty dishes;
  • Maintain cleanliness in the refrigerator;
  • Do a general cleaning of all surfaces, paying attention to cracks where a piece of food can fall;
  • Thoroughly wash the stove, oven, and microwave oven, removing grease;
  • Clean the sink from the outside and inside because food residues can often get stuck in the plum;
  • Replace old sponges and rags;
  • Take out the trash on time and thoroughly wash the container with a disinfectant to prevent fruit flies in the trash can.


Regularly change the water in the pet’s drinker and hide the remains of its food.
Plants in pots:
Loosen the ground, remove leaves, and wash flower pots with a cleaning agent. If you find pests in the soil, you should replace the soil and treat the plants with special means;
Plant geranium, basil, or mint in a pot — the aroma of these plants repels drosophila.
