Clothes Moths: How to Identify and Stop Damage to Woollens and Silks

Small holes in woollens and silk are often caused by clothes moth larvae, not the adult moths.

The short answer

Clothes moth larvae feed on natural fibres such as wool, silk, fur and feathers, especially if soiled. Adult moths are small, buff-coloured and avoid light. Wash or dry-clean before storing, use airtight containers, keep wardrobes clean and aired, and inspect regularly. Treat infested items by washing, dry cleaning or professional treatment.

Identification

• Small, buff, narrow-winged moths in dark places.
• Larvae in silken tubes on fabric.
• Irregular holes and webbing.

Stop damage

1. Wash or dry-clean before storing.
2. Store in airtight bags or boxes.
3. Air and brush woollens regularly.
4. Vacuum wardrobes and corners.
5. Isolate and treat infested items.

Prevention

• Keep clothes clean.
• Control humidity.
• Inspect seasonally.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.
