Our reader’s description of this specimen is pretty spot-on. So, what is this creature? Our first idea is that this could be a carpet beetle larva. Carpet beetle larvae are common household pests, and our readers discover them all of the time! They feed on a wide variety of items found around a home including wool, felt, feathers, fabrics, upholstered furniture, and carpet. In a bathroom, carpet beetle larvae might feed on towels, curtains, or bath mats. While the creature in question might be a carpet beetle larva, we aren’t completely convinced. Some carpet beetle larvae have a tear-drop shaped body, and the size is a match, but carpet beetle larvae aren’t usually white. They are typically a shade of brown or orange. However, this might just be a carpet beetle larva that is lighter than the typical carpet beetle larva.

Another idea is that our reader has found immature black soldier fly larvae. Mature black soldier fly larvae, or BSFL for short, are black or dark brown. However, immature BSFL are initially white, and they darken as they mature and grow! BSFL are excellent decomposers. They excel at breaking down decaying organic matter, so a bathroom (especially the toilet or trash can) might be a good home for these larvae.

We aren’t sure if our reader has discovered carpet beetle larvae, black soldier fly larvae, or something else entirely. No matter the species of creature our reader has found, getting rid of these visitors will likely depend on a thorough cleaning session.¬†We recommend she give her bathroom a total scrub down (including wiping out the trashcan, washing all towels, and scrubbing the drains) to eliminate any potential food sources for small worm-like organisms.
