What is the primary food preference of adults of the black carpet beetle?

The primary food preference of adults of the black carpet beetle is fabrics. Adult black carpet beetles are particularly attracted to animal-based fibers such as wool, fur, and silk, which they use for sustenance. These beetles can cause significant damage to clothing and textiles made from these materials as larvae feed on them. While they may also be found near grains and wood, their primary diet centers around the keratin and other protein-rich substances commonly found in animal materials. Understanding this preference is essential for effective pest management strategies, particularly in preventing infestations in homes and businesses that store textiles and fabrics.
