What dietary preference do clothes moths have?

Clothes moths primarily have a dietary preference for materials of animal origin, which includes wool, silk, feathers, and fur. Their larvae are the stage that causes damage, as they feed on these keratin-rich fibers found in various textiles and garments. This feeding behavior is driven by the need for proteins that are abundant in these materials, particularly keratin, which constitutes a significant part of hair and other animal products.

Their attraction to animal-based fibers is critical for understanding how to prevent infestations, as it means that natural fabrics and materials are at higher risk compared to synthetic ones. Knowing this preference can help implement targeted control measures, such as proper cleaning and storage of garments, particularly those made of wool or silk, to reduce the likelihood of encounters with these pests.
