Linen or Moth Larva

Indoor environments, particularly in dark, undisturbed areas like closets, carpets, or upholstery where natural fibers are present.

Natural protein-based fibers including wool, silk, fur, feathers, and sometimes synthetic blends containing organic matter.

The larvae are often photophobic (avoid light) and spin silken tubes or cases as they feed. They are the stage of the life cycle responsible for textile damage.

Risk: Causes significant damage to clothing, rugs, and household textiles. Benefit: In nature, they act as scavengers by breaking down keratin-rich materials like hair and feathers.
