Clothing moth larva

Natural Habitat

Indoors, especially in dark, undisturbed areas where animal fibers (wool, silk, fur, feathers) are stored. Can be found in closets, attics, rugs, and upholstered furniture.

Diet & Feeding

Keratin-containing materials, such as wool, fur, silk, felt, feathers, and lint. They do not feed on synthetic fibers but may damage them while attempting to reach natural fibers.

Behavior Patterns

Larvae are destructive feeders, creating irregular holes in fabrics. They prefer dark, humid, and undisturbed locations. Adults are poor flyers and are attracted to light but avoid it at night. The larval stage is the most damaging. They spin silken tunnels or cases as they feed. The entire life cycle can range from 65 days to 4 years, depending on environmental conditions and food availability.

Risks & Benefits

Risks: Significant pest of textiles, clothing, carpets, and museum specimens made of natural fibers, causing damage. Benefits: None known for humans; they contribute to the decomposition of animal remains in nature but are primarily considered household pests.
