Houseflies can be kept out of homes this July without using chemical sprays, simply by performing a two-minute task: cleaning the sink drain. According to pest control expert William from Pest Buddy, flies—especially drain flies—breed in the moist organic film that builds up inside drains and plugholes. Regularly cleaning and disinfecting drains removes a hidden breeding site and food source that is easy to overlook.
Why Flies Invade Kitchens in Summer
Flies become a major nuisance in summer because their eggs hatch faster in warm temperatures. They enter homes not only to find food but also to locate safe areas to reproduce. Many people do not realize that flies often hide in dark corners of kitchens, and once inside, their eggs can hatch in less than a day, making removal difficult. Insect repellents contain poisonous chemicals that can linger on surfaces, posing risks to children and pets.
The Simple Solution: Clean Your Sink Drain
William advises that the most efficient way to deter flies is to check and clean your sink drain regularly. Flies are attracted to the smell of food emanating from drains. Sinks accumulate leftovers, crumbs, and vegetable peels daily, which turn into greasy sludge that sticks to pipes. The drain is warm and secluded, making it an ideal spot for flies to lay eggs.
How to Clean Your Sink Drain
Keeping a sink drain clean is straightforward: pour boiling hot water down the plughole to break up food residue and kill any flies already present. Additionally, pouring washing-up liquid or soda crystals down the sink effectively tackles grease. During summer, clean your sink weekly—or daily if you suspect an infestation—to prevent odour buildup that attracts flies. Wiping kitchen surfaces, sweeping the floor, and not leaving dirty dishes in the sink also help, as even a tiny crumb can attract flies.
Long-Term Fly Prevention
A fly-free kitchen does not require special gadgets or bottles; spending a few minutes clearing away food residue is enough to discourage flies for the rest of the summer. This method avoids toxic sprays and ineffective natural remedies, focusing instead on overlooked areas like the sink drain.
