Little Black Worms are Drain Fly Larvae

We just got a video from a reader that displays tons of little black worm-like organisms she found near a drain at her work. The video is a minute long and captures the movement of these creatures and emphasizes their vast numbers. Our reader wonders if these are drain flies.

We are unable to include videos, but we took a screen shot of a scene from the video to include in this post.  As we mentioned, there are a lot of these organisms. We believe she is dealing with larvae, not worms, but are these drain fly larvae or another type?

Based on the location she discovered them in (near a drain) and their appearance, we are confident in our readers guess: These are drain fly larvae!

The presence of drain fly larvae indicates that drain flies have been breeding in the drains. Getting rid of these larvae will require getting rid of the flies’ food source, which can be a tricky job. These flies feed on organic material like the grime and grit that lines drains.

Since our reader discovered these in her workplace where there are many industrial sized drains, cleaning out the drains could be too much of a task for a single person. She might want to recruit her coworkers to help scrub out the drains with pipe brushes, or hire a professional for a small fee. However our reader decides to handle these drain flies and their larvae, we wish her luck.
