Why Do Moths Eat Wool Rugs?

Moths eat wool rugs primarily due to the presence of keratin, a protein found in animal fibers. Adult moths are not the ones causing the damage; rather, it is their larvae that feed on wool. This behavior is problematic for wool rug owners.

The University of California Agriculture and Natural Resources defines moth larvae as the destructive stage of moths that frequently infest textiles made from natural fibers, such as wool.

The main reasons behind moth larvae feeding on wool rugs include their dietary needs and the conditions in which they thrive. Moth larvae are drawn to natural fibers like wool because they require nutrients found in keratin. Wool provides a rich source of this protein, which supports their growth and development.

In more specific terms, moth larvae are known as caterpillars; they consume fibers that contain keratin to sustain their energy requirements. Keratin is a structural protein common in hair, horns, and other animal products. While adult moths feed on nectar, the larvae engage in destructive feeding as they grow.

Environmental conditions also play a significant role in moth infestations. Wool rugs can attract moths in poorly ventilated areas with high humidity or in places with clutter, such as attics and basements. For example, rugs that are rarely moved or cleaned may accumulate food residues, skin flakes, and organic materials that further entice these pests.

In conclusion, moth larvae eat wool rugs because they require keratin found in wool for their growth. Poorly maintained environments with suitable conditions for larval development can lead to infestations, causing damage to valuable woolen textiles. To prevent this issue, it is essential to ensure proper cleaning and maintenance of wool rugs.
