What materials do fabric pests primarily feed on?

Fabric pests, particularly insects like moths, primarily feed on animal-based fibers such as wool and silk. These pests are attracted to the keratin found in animal fibers, which provides the necessary nutrients for their growth and development. Their feeding habits can cause significant damage to clothing, upholstery, and other textile products made from these materials.

Other materials, such as cotton and synthetics, are not their primary food sources. While some pests might occasionally feed on blends or very small amounts of these materials, they are not as reliant on them as they are on animal fibers. Grains and seeds, along with processed foods and cereals, are targeted by different types of pests, such as pantry pests, which have completely different feeding behaviors and ecology. Understanding the specific dietary preferences of fabric pests is essential for effective pest management and control strategies.
