How to Get Rid of Small Flies in the Bathroom: Effective Solutions for a Common Bathroom Problem

Small flies in the bathroom—often called drain flies, fruit flies, or fungus gnats—are a common nuisance in many homes. They thrive in moist, humid environments and are attracted to decaying organic matter found in drains and crevices. To eliminate these pests effectively, start by identifying their breeding grounds. Check drains, the overflow hole of your sink, under sink cabinets, and any areas where moisture accumulates. Clean these spots thoroughly using a stiff brush and a mixture of baking soda and vinegar, followed by boiling water to kill any remaining larvae. Regularly empty bathroom trash bins, fix leaky faucets, and keep surfaces dry to reduce breeding opportunities. You can also use homemade traps, such as a dish filled with apple cider vinegar covered with plastic wrap (poke small holes to let the flies in), to capture adult flies.
