Latin name: Tineola bisselliella and Tinea pellionella
Clothes moths are common household pests found throughout Australia and are a frequent issue in residential, commercial, and strata environments. They are particularly problematic in properties with woollen carpets, natural fibre clothing, and stored textiles.
Clothes moth larvae feed on natural fibres containing keratin, such as wool, silk, fur, feathers, and some blends. Adult moths do not cause damage; however, their presence indicates an active breeding population.
Clothes moth activity occurs year-round indoors but increases during warmer months. In Western Australia, spring and summer conditions support faster development and higher infestation pressure, especially in undisturbed storage areas.
Lifecycle
The clothes moth lifecycle consists of egg, larva, pupa, and adult stages and can take several months to complete depending on environmental conditions.
- Eggs are laid directly on or near suitable food sources
- Larvae hatch and feed on natural fibres, causing damage to clothing and furnishings
- Larvae may live for several weeks to months, depending on food availability
- Pupation occurs within silken cases or cocoons
- Adults emerge, mate, and lay eggs, continuing the cycle
Larvae are responsible for all fabric damage.
Identification
- Adults:
- Small moths measuring 6–8 mm long
- Pale beige to golden in colour
- Narrow wings with fringed edges
- Weak fliers that avoid light
- Larvae:
- Cream-coloured caterpillars with brown heads
- Often hidden within fabrics or silken tunnels
- Signs of activity:
- Holes in clothing or textiles
- Silken webbing or cases on fabrics
- Larval droppings (fine grit-like material)
Clothes moths are rarely seen flying in open areas and prefer dark, undisturbed locations.
Damage
Clothes moths cause significant damage to textiles and stored materials.
- Irregular holes in woollen clothing, carpets, and upholstery
- Damage to stored garments, blankets, and curtains
- Gradual deterioration of fabrics over time
- Costly replacement of damaged items
- Infestations often spread unnoticed in wardrobes and storage areas
Clothes moths do not bite and pose no health risk to humans.
