Although many assume it’s a common insect that appears by chance, the drain fly, also called a sewer fly or shower fly, is often a sign of a plumbing problem. Its small size and slow flight make it inconspicuous at first, but when it starts appearing frequently in the bathroom or near the sink, it can become a constant nuisance.
This curious insect tends to settle in damp, poorly ventilated areas rich in organic waste. This is why bathrooms are one of its favorite haunts. While it generally doesn’t pose a serious health risk, its presence can indicate cleaning or maintenance issues that should be addressed as soon as possible.
The shower fly has a very distinctive appearance. It is usually small, gray or dark brown, and its wings have a texture similar to those of a tiny moth. Unlike other flies, it does not typically fly long distances. It usually stays near pipes, damp walls, drain grates, or areas of condensation.
