Clothes moths are known to prefer feeding on which type of garments?

Clothes moths, particularly the common species known as Tineola bisselliella, are attracted to protein-rich materials, which are often found in animal-based fibers. Recently cleaned wool garments present an ideal environment for these pests because the oils and residue from cleaning can still retain scents that attract moths and may have remnants of organic matter that the larvae can feed on.

Wool is made from keratin, a protein that serves as a primary food source for clothes moth larvae. Although moths can potentially feed on other fabrics, they demonstrate a marked preference for wool, especially items that are stained or carry scents indicative of human presence, as these can signal a suitable nesting area for their larvae.

While silk is also a natural fiber that can be susceptible to moth damage, the degree of preference is lower compared to wool, particularly when wool garments are freshly cleaned and may not be stored properly. Cotton and synthetic fabrics are less attractive to clothes moths because they lack the protein-based materials that the larvae need for growth. Thus, the focus on cleanliness and natural fibers is crucial in understanding the behavior of these pests.
