Brown House Moths attack a wide variety of materials including cereals, cereal products, textiles, leather and cork. The Brown House Moth tends to scavenge whilst the White Shouldered House Moth is generally found infesting food.
Damage takes the form of clean, irregular holes and in the textiles these generally occur around seams. There is no webbing or excrement present and by the time the larvae are observed, considerable damage has often been done by the Varied Carpet Beetle.
Carpet Beetle digest the protein keratin which is the principal constituent of fur, feathers and the wool used in the manufacture of clothes, upholstery, fabric, carpets, under felts and blankets. The larvae feed on all materials, clothes and textiles of animal origin.
