Bangkok Reddit user finds harmless plaster bagworms

A Reddit user in Bangkok discovered plaster bagworms in their condo, prompting online identification of the harmless insects. These larvae create protective cases from dust and fabric fibers. The user's post showed small, oval-shaped objects on the ceiling, mistaken for debris. Commenters identified them as plaster bagworms, moth larvae that feed on household dust and organic matter. Plaster bagworms, while not harmful to humans, can damage fabrics. Their presence often indicates poor indoor cleanliness, and control involves regular cleaning and dust reduction.
