If you do nothing, the beasts multiply en masse: But there are simple tricks to ban fruit flies from the kitchen.
Especially in summer, fruit flies multiply. At higher temperatures, various scents lure them into the kitchen. They lay their eggs on overripe fruit or rotting potatoes, and they are also magically attracted to vinegar or wine. According to the North Rhine-Westphalia Chamber of Agriculture in Münster, if you want to get rid of them again, you first have to find the place where they reproduce.
Substances in question should then be thrown away, decaying parts sorted out and supplies that can still be used should be stored in an airy and dry place. According to the information, fruit is best kept in the refrigerator, because it does not lose its aroma even at low temperatures.
Otherwise, it is advisable to regularly examine the fruit for further infestation and to keep it covered. Waste bins should also remain closed. Empty bottles, which the little flies might visit because of the remains of the drink, are best rinsed out as a precaution.
