Household Casebearer Found in Bathroom

We just received an interesting message from a reader: I have a small insect or worm that emerges from the baseboards in my bathroom. Initially, it looks like a chip of white paint. There are no antennae or legs visible. It is eye-shaped, and sometimes has tiny spots of brown. Can you help me identify it?

The message lacks an attached picture, which makes definite identification impossible. We aren’t completely sure what our reader has discovered in their bathroom, but we think it might be a household casebearer.

Household casebearers are the larvae of moths, and they get their name from the shell they create during their larval stage. These camouflaging cases are constructed using secreted silk, soil, dust particles, and other fibers. These shells are a comfortable and safe home for the larvae until they are ready to transform into moths. We believe this might be what our reader found because of the eye-shape they described, and that it looks like a white chip of paint with brown spots on it. These brown spots could be recent additions to its case, like sand or dust.

Our reader should compare photos of household casebearers with the critter they found, and see if it is a match. If not, they can send in photos so we can make a more accurate identification!

In summary, a reader has found a small creature in their bathroom that looks like a chip of paint. We think this might be a household casebearer, but we cannot be certain without photos.
