Today we will look at two photographs that a reader sent us. They show a small area of her kitchen blinds covered in worm-like organisms. The area is about the size of a nickel and it contains dozens (or maybe even hundreds) of the minuscule creatures. She explained that she found a dead moth in her house about two days ago and is curious if the sudden appearance of these larvae has anything to do with the moth.
We have written several articles in response to readers who have found similar clumps of larvae on their walls, windows, and other surfaces of their homes. We believe these larvae are probably moth fly larvae. We have never figured out exactly why these larvae appear in large quantities in small areas, but we think it could have something to do with the dead moth our reader mentioned. Moth fly larvae feed on decaying matter, and adults lay their eggs on the food source for their larvae so that when the eggs hatch the larvae can begin eating right away. An adult moth fly might have laid her eggs where the dead moth was, and now the larvae have hatched and begun to feed.
These larvae are harmless and nothing to stress about! To say goodbye to them our reader will simply need to clean off her window blinds. She can use a spray that is designed to eliminate organic material and a washcloth or paper towel. If our reader finds moths or other specimens in her home on a regular basis, she might want to check to make sure her doors and windows are properly sealed so that there aren’t small cracks where creatures can crawl through.
In summary, one of our readers discovered a group of tiny worm-like organisms on her window blinds. We believe these specimens are moth fly larvae.
