Phereoeca uterella

A species of Household casebearer moths

The household casebearer is a moth commonly found in households in warm, humid areas. The larvae form a distinctive silk case around themselves for protection and camouflage. They then feed on silk (mostly from spider webs), wool, human hair, and dander before entering the next stage of their life cycle.

Larva As a larva, household casebearer emerges with a voracious appetite, its body elongated and worm-like, lacking wings. The larva continuously feeds and grows, molting several times to accommodate its increasing size.
Pupal The pupal stage of household casebearer is a non-feeding, transformational phase. Encased within a cocoons, household casebearer undergoes drastic morphological changes, its tissues reorganizing to form the adult structures.
Adult Emerging from the pupa, the adult household casebearer’s development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

Habitat Preferences of Household casebearer Through Different Life Stages
The eggs of household casebearer are often laid on fabrics, particularly those containing keratin. The larvae prefer dark, protected spaces within closets or drawers, nestled among clothing or other materials suitable for their consumption. Searching for the larvae would involve inspecting these secluded areas. Pupation typically occurs within the same environment as the larvae, as they construct silken cases around themselves, often adhering them to fabric surfaces. Adults, on the other hand, are drawn to light and may be seen flying in areas such as near windows or lamps. Seeking adults would entail checking around light sources during their active periods.

How and Where Can You Find Household casebearer at Different Life Stages
Egg Household casebearer eggs are extremely small and can be located in clusters on fabric or in dark, undisturbed areas. Using a magnifying glass and good lighting, inspect susceptible materials like wool or silk.
Larva Household casebearer larvae can be found within silken cases which they drag around as they feed. Inspect wardrobes, closets, and drawers, particularly in the corners or folds of stored clothing or fabrics.
Pupal Pupae of household casebearer will often be within their larval cases attached to potential food sources. To locate them, check the same areas suggested for finding larvae, with special attention to seams and hidden spots.
Adult Adult household casebearer can be attracted to lights at night. However, they are not strong fliers, so placing pheromone traps in areas where clothes or fabrics are stored can be an effective way of finding them.

  • Store long-wearing clothes in the sun and dry them completely before putting them back in the closet. It can be better to seal them with plastic bags.
  • Discard old clothes that you don't use. Don't just put them there to crowd out space and become a habitat for pests.
  • Pay special attention to cardigans, sweaters, and leather products.
