We believe the creatures our reader found in his bathroom are probably millipedes. Millipedes are harmless and not usually classified as household pests, which means they don’t cause damage or destruction inside a home, so our reader has nothing to worry about!

We identified the brown organism our reader found in her shower as a millipede. These arthropods are considered to be harmless and are not parasitic as our reader feared.

A concerned reader wrote to us a while back about some red worms on her bathroom floor. (Technically, the worms in the bathroom are “reddish-brown,” to use the reader’s exact phrase.) She has found the worms twice now, causing her some concern because she has never seen the creatures before in the 12 years she has lived in her house. The worms have a “snail head,” and the reader didn’t notice any legs. Naturally, the reader was curious about what she was finding, and so the question before us is this: what are the red worms in her bathroom?
