Moth heat treatment in London
Heat treatment raises a room, or a chamber of belongings, to a temperature no stage of the moth survives, then holds it there long enough to reach deep into carpet, upholstery and folded textiles. It is usually one visit, without insecticide on the heated items, which suits homes full of good wool and silk. Published London prices start at £534 for a studio or one-bed flat and £1,134 for three bedrooms.

When heat is the better choice
- A spray course has not stopped the damage, or the moths returned within months.
- You would rather keep insecticide off rugs, cashmere, tailoring or upholstery.
- Carpet, underlay and sofas are affected, and spray only reaches the surface.
- Somebody at home is pregnant, has a baby or has a breathing condition.
- You want the job done in one day rather than over several weeks.
- Valuable textiles need treating with the temperature and humidity controlled.

Heat prices are the published London starting prices from the same firm’s London price list, the only domestic heat prices we could find in public, and they include a spray. Read 28 October 2026. A guide, not a quote. The price calculator compares heat with a spray course.
What a good quote covers
Ask for these six points in writing before anyone starts, so you know what you are paying for.
- Target temperature
- The temperature reached at the coldest point in the room, not just the air near the heater, and how long it is held.
- How it is measured
- How many sensors are used and where they go: inside furniture, under rugs, in folded piles.
- Humidity and delicate pieces
- How moisture is managed for antiques, instruments, artwork, silk and old rugs, or what should leave the room first.
- What must come out
- A written list of things to remove: candles, aerosols, medicines, plants, pets, electronics and anything that can melt.
- Rooms included
- Every room heated, and whether a spray of untreated areas is part of the price.
- Afterwards
- How long the room takes to cool, what you can put back that day, and any follow-up.
How a heat treatment day usually runs
- The week before
Survey and list
The firm checks the rooms, the electrics and what is in them, and gives you a list of what to take out.
- Morning
Set up
Heaters, fans and temperature sensors go in. Wardrobe doors and drawers are opened and clothes spread out so heat can get in.
- Several hours
Heat and hold
The room is brought up to temperature and held until the sensors show every point has been reached for long enough.
- Late afternoon
Cool and check
The room cools down, the technician checks the readings with you, and any areas outside the heated rooms are sprayed.

Find a specialistQuestions Londoners ask
What temperature kills clothes moths?
Conservation guidance on MuseumPests treats a short exposure at about 55°C as enough to kill every stage, eggs included. Firms aim higher at the coldest spot to be sure, so ask what they target and how they measure it.
Will heat damage my furniture or clothes?
A well-run treatment controls the temperature so ordinary furnishings, wool and cotton are fine. Old veneers, glued antiques, vinyl records, candles and some plastics can suffer, which is why you get a list of what to remove.
Does heat treatment stop moths coming back?
It kills what is in the heated rooms that day, but leaves nothing behind to stop a new infestation. Clean storage, sealed bags and regular vacuuming do that job.
Is heat treatment possible in a London flat?
Usually, yes. The firm will check the power supply and the space for its equipment during the survey. In a mansion block, let the porter or managing agent know about the equipment coming in.
Can I freeze things instead?
For small items, yes. English Heritage advises sealing them in freezer bags at -18°C for at least two weeks, which kills adults, eggs and larvae. A rug or a sofa will not fit, which is where heat earns its price.
