slowly, a foul odor persists, or flies appear in different parts of the house, it’s best to consult a professional.

The appearance of drain flies doesn’t always indicate a serious problem, but it does signal excessive moisture and a buildup of debris. Regularly cleaning drains, checking pipes, and ensuring good ventilation are simple measures that can prevent these curious insects from establishing a permanent presence in the bathroom.
