Their diet consists of materials containing keratin, a protein found in animal products. They can therefore feed on wool, feathers, fur, insect remains, paper, and even organic particles present in household dust. Since their consumption is quite low, they rarely cause damage.
Unlike other moths associated with clothing or food, the case-bearing clothes moth is not considered a pest. Its presence does not indicate a dangerous infestation or a risk to human health. It typically appears in environments where dust, fibers, and organic debris accumulate, which is common in any home.
Therefore, controlling it requires neither chemicals nor drastic measures. Regular and thorough cleaning is usually enough to reduce its presence.
