(Length: up to 1/2″) These are small yellowish or brownish moths. Larvae spin a silken tube or case which they drag around themselves to protect them from the environment and their natural enemies. Eggs are laid on products the larva will consume such as: wool, feathers, fur, hair, animal and fish meals and milk powders. Adults do not feed on fabrics. Only the larvae damage household goods. They are not attracted to light, preferring dark, protected areas. Cedar closets will not prevent them from entering.
