Textile pest

Clothes moth

Small moth larvae that feed on animal fibers in dark, undisturbed storage. Silk cases or tubes distinguish them from carpet beetles.

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
Highest-value next observation

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.

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.

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.

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.
