Brown house moths generally consume clothing materials, such as silk, wool, feathers and more. Brown house moths can chew through and destroy clothing quickly, and they prefer to live and feed in dark places. These moths do the most damage when they are in the larval stage, as adult moths do not feed on clothes and household materials, say experts at Orkin.
In addition to clothes, house moths can consume food items such as pantry goods, notes Orkin. Although they might eat a variety of materials, house moths prefer wool. They generally eat items made from natural materials, which include pillows, blankets, stuffed animals and toys, in addition to clothes. They generally avoid synthetic materials, but may eat items made from mixed materials.
Although they belong to the family of moths, individuals in the house moth family vary widely in appearance. Some are light brown or tan, while others appear dark brown and have reddish tints. While some moths enter peoples' homes and consume their clothing, others breed in agricultural areas, such as crop fields and fruit farms. Some larvae pose little harm to humans apart from damaging their clothes and fabrics, but others sting and wreak havoc on crops. Signs of moths in or around the home include webs, cocoons, droppings and evidence of fabric or crop damage.
