Casemaking Clothes Moth
Females lay eggs one at a time or in clusters. The eggs hatch within 4-10 days. The destructive larva will feed on fabrics and use the excrements to form their pupation cases. This will occur through a series of molts ranging from 5-45. The adults will emerge from cases within 2 months typically but can take several years for this to occur. Once they have emerged, they will die shortly after they lay eggs, usually within a month. Adults do not feed.
