Clothes moths usually feed on

• A. Cotton
• B. Nylon
• C. Wool
• D. Silk

Answer: (C)

Clothes moths damage fabrics because their larvae feed on natural protein fibers. They can digest keratin and other proteins found in fibers like wool, fur, and silk, which makes wool a prime target. Cotton is plant-based cellulose, not protein, so it isn’t a preferred food, and nylon is synthetic and not something the larvae typically digest. Silk is also a protein fiber, but wool is the most common and readily damaged substrate for clothes moth larvae, making it the best answer.
