Physical Characteristics

The casemaking clothes moth adult’s wingspan is 1/2 inch, with the length of its body is 1/4 inch (not to be confused with food- and grain-infesting species of moths, whose bodies are 1/2 inch long). Its body and wings are brownish, with three faint darker spots on each forewing; the hindwings are pale brown-gray.

Casemaking Clothes Moth

Behavior

The casemaking clothes moth feeds on synthetic and or animal materials, making it a fabric pest. It likes materials that contain keratin, a fibrous structural protein found in hair, feathers, nails, claws and wool. Like the similar webbing clothes moth, you really won’t know these moths – or more accurately, their larvae – have paid you a visit until it’s too late, when the clothes in your closet look like Swiss cheese.

Treatment

First, the casemaking clothes moth must be properly identified as the culprit. Next, the home or place of infestation must be inspected thoroughly. Also, areas with conditions conducive to this moth should be cleaned up – hair, fur and objects containing keratin should be removed, clothes should be washed or dry-cleaned, carpets should be shampooed, and fabric-covered furniture should be cleaned. Call your Clark technician to make sure this is the moth that is causing your problem, and will know exactly what measures to take to make your home moth-free.
