Typically, these flies are either drain flies or fungus gnats. Their presence is often a sign of excess moisture or organic buildup in drains. To effectively get rid of them, start with a thorough cleaning: pour boiling water down your drain daily for a week, then use a mixture of baking soda and vinegar to help dissolve any organic material inside the pipes. Scrub your drain covers, wipe down tiles, and mop up any standing water in the space. Eliminating their breeding grounds—usually the moist, organic deposits in bathroom drains—remains the key. You can also set vinegar traps (a bowl of apple cider vinegar covered with perforated plastic wrap) to catch adult flies.As a designer, I always consider not just the quick fix but the bigger picture—integrating practical, aesthetic, and long-term solutions. For persistent fly problems, consider improving your bathroom's ventilation, upgrading old fixtures that may harbor bacteria, and selecting easy-to-clean surfaces. These changes not only solve the current issue but help prevent it from recurring. Thinking about the future, having a well-planned bathroom design tool can help you visualize and implement changes that deter pests, enhance cleanliness, and boost your bathroom’s overall appeal.Tips 1:Keep your bathroom as dry as possible, especially overnight, by wiping down wet surfaces and using a dehumidifier if needed.
