Life Cycle
Moths go through metamorphosis. The moth goes through four lifestages: egg, larva, pupa, and adult. The different species of clothes-eating moths are difficult to tell apart, but there’s no real need to identify the particular species, since the control measures will be identical.

Eggs
A single female may deposit from 100 to 300 eggs in clothing and household furnishings. They are soft white to ivory-colored, oval shaped, and about 1/25 inch long. Eggs hatch in one to two weeks during the summer (or in heated rooms), while in unheated rooms hatching may take longer.
Larvae
Depending on the species they can be small cream-colored caterpillars or shiny, creamy white in color, and no more than 1/2-inch long. The amount of time it takes for a larva to mature varies greatly, from about 40 to over 200 days. This life stage is when the most damage is done to your fabrics as the larvae will feed until they spin their pupa.

Pupa
Moths spin silky pupae in the larval feeding area and in about 1 to 4 weeks they hatch into winged moths.

Adult
Soon after emerging from the pupae, the adult moth will mate and begin the cycle again. Adult moths have two pairs of wings covered in pigmented scales with a span around ½ inch. Moths may vary in appearance based on species, but the common cloth moths are usually shades of grey or brown to reddish brown, some even having distinct spots on their wing.
