What type of materials does the carpet beetle's larvae prefer to feed on?

The choice indicating that carpet beetle larvae prefer to feed on animal-based products is correct because these larvae are primarily known for their diet consisting of organic materials that come from animal sources. This includes common household items such as wool, silk, fur, leather, and even feathers. The keratin found in these materials is particularly appealing to carpet beetles because it provides the necessary nutrients for their growth and development.

In contrast, options such as plant-based products or granular foods are not primarily sought after by carpet beetle larvae. While certain plant materials might be consumed in the absence of their preferred food sources, they do not provide the same nutritional benefits that animal-based materials do. Likewise, dried fruits are not a typical food source for carpet beetle larvae, as their feeding habits are more specialized towards organic materials derived from animals. Understanding the feeding preferences of carpet beetle larvae is important for effective pest management and prevention strategies within residential and commercial environments.
