What is the primary diet of adult carpet beetles?

The primary diet of adult carpet beetles consists of textiles and organic materials. These insects are particularly attracted to animal-based fibers, such as wool, fur, and silk, as well as other organic debris. The larvae of carpet beetles are known for causing damage to household items, as they feed on materials that contain keratin and other proteins, which are found in natural fibers. Adults primarily seek out food sources that will support their reproductive processes, which often leads them to lay eggs in areas where their larvae will have ample food resources. This affinity for textiles and organic materials is a significant factor in why they are often found in homes, particularly in areas where debris may accumulate.
