What additional materials may carpet beetle larvae feed on?

Carpet beetle larvae are known for their broad diet, primarily feeding on natural fibers. Among the additional materials they may consume, leather and woolen items are particularly significant because these materials contain keratin, a protein that the larvae are capable of digesting. This ability allows them to thrive in environments where such organic materials are available.

Carpet beetles are often associated with damage to clothing made from animal fibers, such as wool, silk, and leather, highlighting their preference for these types of materials. Finding larvae in woolen garments or leather goods is a common indication of an infestation. Other options, while they may contain some organic components, are not typically sought out by carpet beetle larvae in the same way as leather and woolen items are. Understanding their feeding habits is essential for effective pest control and prevention strategies in infested areas.
