“My sister found a small white worm on her bed”, writes this reader in his submission regarding the segmented, clear, worm-like critter pictured below. “What is it?” Based on the photo alone, it is hard to pinpoint one single species of worm-like creature. There are actually quite a worm-like critters that look like this that people have found in their homes in the past, including fungus gnat larvae (which eats decomposing organic materials in mulch) and lilac ash borer larvae (a pest which eats and through the wood in one’s home). However, the location in which this one was found tells us that this is probably a flea larva.
