what causes fruit flies in the house

Fruit flies in the house are primarily caused by the presence of overripe, rotting, or fermenting fruits and vegetables. They lay their eggs on these food sources or in moist organic materials such as drains, garbage disposals, empty bottles, and trash. Fruit flies are attracted by the smell of ripening or decaying produce and can reproduce quickly, often laying up to 500 eggs, leading to infestations that develop fast. Other household items like dirty dishcloths, sink strainers, damp mops, and cleaning rags can also serve as breeding grounds if they harbor food residues or moisture. Essentially, fruit flies are drawn to fermenting, sweet, or damp environments where their larvae can develop.
