Care & Repair
Moth Damage
Identifying an active infestation, stopping it, and repairing what it ate — the threat that destroys rugs faster than decades of foot traffic.
A moth infestation can strip a wool rug to its foundation in a single season. Nothing else in ordinary domestic life destroys rugs that fast.
What is actually eating it
Not the moths. Adult clothes moths do not feed at all — they mate and lay eggs. The damage is done by the larvae, which eat keratin: the protein in wool, silk, hair and feathers.
Two species matter. Tineola bisselliella, the common clothes moth, and Trichophaga tapetzella, the carpet moth. Both prefer conditions that are dark, undisturbed and soiled — because soiling provides the additional nutrients the larvae need alongside the keratin.
That is why rugs get eaten under sofas, along the edges against walls, and above all in storage.
The signs
- Frass
- Fine sand-like grit, the colour of the wool it came from
- Webbing
- Silky tubes or matted patches on the pile surface
- Bald patches
- Pile lifts away cleanly, leaving bare foundation
- Larvae
- Small cream grubs, 5–10mm, often inside silk tubes
- Adults
- Small buff moths that run and flutter rather than fly well
Check under the furniture, not the open floor
Moths avoid light and traffic. The open middle of a rug is almost never where it starts. Lift the rug and look underneath, look under every piece of furniture standing on it, and check the edges against the wall — twice a year.
Seeing adult moths flying in a room is a late signal, not an early one.
Stopping an active infestation
Act immediately; larvae eat continuously.
- Isolate the rug. Take it out of the room so the infestation does not spread to other wool textiles.
- Vacuum thoroughly, both faces, paying particular attention to the base of the pile and the edges. Empty the vacuum outside immediately.
- Have it professionally washed. Immersion washing kills eggs and larvae and removes the soiling that attracted them. This is the definitive step — DIY vs professional.
- Freeze small items as an alternative: 72 hours at −18°C or below, sealed, then thaw and re-freeze after a week to catch anything that survived.
- Treat the room, not just the rug. Vacuum the floor beneath, the skirting and any upholstery.
Pheromone traps catch adult males and are useful for monitoring whether you still have a problem. They do not solve an infestation on their own — the larvae are already in the rug.
Repair afterwards
Moth damage is repairable on a hand-knotted rug: the affected area is repiled knot by knot, or rewoven if the foundation has gone too.
It is priced by area, so catching it early is the difference between a small job and a large one. See rug repair.
On machine-made and hand-tufted rugs there is nothing to repair into.
Prevention
The single most effective habit is disturbance. Moths need undisturbed conditions, so moving the rug, vacuuming under furniture, and rotating twice a year prevents most infestations from establishing.
Beyond that:
- Never store a rug unwashed — soiled wool is what attracts them. Rug storage.
- Vacuum the reverse twice a year, and under furniture rather than around it.
- Inspect twice a year, lifting the rug and looking underneath.
- Cedar and lavender are mildly repellent and lose potency; refresh annually and treat them as a supplement rather than a defence.
Wool's vulnerability here is the counterpart to everything else it does well — see wool rug properties and wool rugs: pros and cons.

Common questions
How do I know if my rug has moths?
Look for fine sand-like grit (frass), silky webbing or tubes on the pile, patches where pile lifts away cleanly leaving bare foundation, and small cream larvae. Check under furniture and along walls — moths want dark and undisturbed.
Do moths eat synthetic rugs?
Not the fibre itself. Clothes moth larvae eat keratin, so wool, silk and hair are at risk and synthetics are not. A blend can still be damaged where the natural component is, and soiled synthetics can host larvae feeding on the residues.
