Professional carpet moth treatment
"Carpet moths" are the same clothes moths that eat jumpers: their larvae feed on wool carpets and rugs, usually where it is dark and undisturbed, under beds, sofas and the edges of the room. A professional treats the whole carpet, its edges and the gap under the skirting, typically £120 to £240 for one room and £200 to £300 for two or more rooms outside London.

When to call a specialist for carpets
- Bare or thinning patches in wool or wool-mix carpet, often along the skirting or under furniture.
- Tufts that pull out easily, or fine, sandy debris where the pile has been eaten.
- Small creamy larvae or silky tubes at the carpet edge when you lift it back.
- Shop sprays or powders have not stopped new damage appearing.
- A valuable or antique rug is affected and you do not want to risk it.
- Several rooms, stairs and landings have carpet that could be affected.

Survey
The technician lifts edges, checks under furniture and finds every area with larvae, including stairs and landings.
Deep vacuum
You or the firm vacuum the whole carpet and its edges, then seal and bin the vacuum contents outside.
Treatment
The pile, edges and skirting gaps are sprayed or the room is heated, with rugs treated alongside.
Follow-up visits
Spray courses return after a few weeks to catch larvae from eggs that survived the first visit.
Questions people ask
Are carpet moths different from clothes moths?
No. Butterfly Conservation and English Heritage list the common clothes moth and the case-bearing clothes moth as the household pests. "Carpet moth" is just the name people use when the larvae are in the carpet.
Why do carpet moth sprays from the shop not work?
They usually reach only the surface, while larvae feed deep in the pile, under furniture and along the edges. Eggs survive and hatch later. A professional treats every hiding place and returns to catch the next hatch.
Do carpet moths eat synthetic carpets?
The larvae feed on keratin in animal fibres such as wool, so pure synthetic carpet is rarely eaten. Wool-rich mixes are at risk, and larvae can feed on dirt, hair and spills in any carpet.
Do I need to replace my carpet?
Usually not. Treatment stops the damage; patches can often be repaired or hidden. Replace a carpet only if the damage is severe, and treat the room first so new carpet is not attacked.
Can a valuable rug be heat treated?
Yes. Museums treat textiles in heat chambers at about 54°C to 60°C with the humidity controlled, according to MuseumPests.net. Ask the firm how it controls temperature and moisture for delicate or antique pieces.
How long after treatment can I walk on the carpet?
With a spray, once it is dry, which is usually a few hours. The firm will tell you how long to stay out. After heat treatment the room can usually be used once it has cooled.
