Evidence signature
Smooth pale larvae, attached silk cases or webbing and clipped natural fibers in dark garment folds.
The strongest identification comes from several independent observations that agree: the physical sign, its exact scale, where it accumulates and a companion clue. One isolated mark is rarely enough.
Most useful evidence
Webbing and silk, Larvae and grubs, Damage and gnawing, Eggs and cases.
Typical locations
Closet and textile storage, Bedroom.
Common timing
Any.
Supporting context
Textile.
What supports this identification
- Silk tube or case attached to fabric
- Smooth pale caterpillar with dark head
- Damage in wool, fur, feathers or felt
- Small buff adult avoiding light
What points away from it
- Hairy carpet-beetle skins
- Pantry webbing tied to food
- Silverfish grazing on paper or starch
Inspect the damage edge for an attached silk case and compare the larval surface for hairs.
A safe first response
Bag affected textiles before moving; launder, freeze or clean using material-safe guidance.
Preserve a clear photograph with scale before cleaning when that can be done safely. Avoid broad pesticide applications until the target and exposure route are understood; an indiscriminate treatment can scatter activity, contaminate surfaces or obscure the evidence.
When to bring in a professional
Professional treatment may help when activity is widespread in inaccessible textile storage.
Common lookalikes
Varied carpet beetle
Anthrenus verbasci
Hairy banded larval skins and irregular grazing damage in lint, wool, feathers or stored natural fibers.
Indianmeal moth
Plodia interpunctella
Silk-clumped food, webbing in package seams and a two-tone adult moth in kitchens or pantries.
Silverfish
Lepisma saccharinum
Silvery tapered body, three tail filaments and irregular surface grazing in cool humid paper or storage areas.
Direct comparisons
Side-by-side decision
Carpet beetle vs. clothes moth damage
Carpet beetles leave hairy skins; clothes moths leave attached silk, tubes or cases.
Open comparison
Side-by-side decision
Clothes moth vs. pantry moth
The food source is decisive: clothes-moth silk stays with animal fibers; pantry-moth silk binds dry food.
Open comparison
Side-by-side decision
Cellar spider web vs. clothes moth silk
Cellar spiders suspend loose three-dimensional webs in open corners; clothes moth larvae keep silk against fibers, cases and feeding damage in dark storage.
