Last week a reader sent us a video of a “worm” she found in her toilet. She asked us if we had any idea what the “worm” might be.

Even though the video doesn’t provide a clear image of the specimen, we are pretty confident that we know what this creature is! We believe this is a moth fly larva.

Moth fly larvae are also called drain fly larvae because they are usually found in a drain associated with a sink, shower, or toilet. They prefer these habitats because they enjoy a moist environment full of decaying matter. Since our reader discovered this in her toilet, that indicates that she should give her toilet a good cleaning. Because these larvae like decaying organic matter, our reader should use a cleaning gel that is specifically designed to destroy that. Once she gives her toilet a good scrubbing she shouldn’t have any more run ins with these larvae.

In summary, we heard from a reader about a “worm” she found in her toilet. We are confident that it is a moth fly larva, a.k.a. drain fly larva.
