What do carpet beetles primarily prefer to eat?

Carpet beetles primarily prefer to eat organic materials found in household environments, particularly items like dried beans, peas, and grains. These insects are attracted to natural fibers and materials that contain protein, such as animal-based products. Dried plant materials, including grains and legumes, offer them the nutrients they require for growth and reproduction.

In addition to being drawn to such products, carpet beetles can also infest wool, fur, feathers, and other natural fibers, which aligns with their natural dietary preferences. Recognizing the significance of stored food items in attracting carpet beetles helps in understanding effective control measures, such as proper storage solutions and maintaining cleanliness in areas where food supplies are kept. This insight emphasizes the importance of regular pest inspections and preventive practices to safeguard against infestations.
