Why Heat Treatment Works Where Sprays Fail
Bed bug treatment fails for one reason far more often than any other: the eggs survive. Everything that makes heat treatment different comes back to that.
It reaches the temperature that kills eggs
Bed bug eggs are the reason infestations come back. They are cemented into cracks, seams and screw holes where a surface spray never lands, and they are unaffected by most residual insecticides. Heat does not need to touch them — it raises the air and the material around them past the thermal death point, so eggs, nymphs and adults all die in the same few hours.
It does not depend on finding every bug
A spray only works where it is applied, so it is only as good as the technician’s guess about where the bugs are hiding. Heat treats the whole room as one volume. Behind skirting, inside the bed frame, under carpet edges, in the back of a wardrobe — it all comes up to temperature together.
It finishes in a day, not over weeks
A chemical programme means two or three visits spread over a month or more, and you live with the bed bugs in between. Heat treatment is a single visit. You leave in the morning and come back to a treated property the same day.
Nothing is left behind in your home
There is no residue, no smell and nothing for children or pets to come into contact with afterwards. That matters in nurseries, care settings and homes with asthma, chemical sensitivity or fish and reptiles — and it is why heat is the only method we will guarantee in writing.
On The Day
What a Heat Treatment Actually Involves
Heat treatment is a controlled process, not just a hot room. This is what happens from quote to hand-back.
We survey and quote before anything is booked
We establish how many rooms are affected and what is in them. Heat is priced per room, so the quote is fixed at this point — you know the total before a technician is booked, and it does not change on the day.
You prepare the property
You will get a written preparation list. Most of it is straightforward — removing aerosols, pressurised containers, candles, medicines, vinyl records and anything heat-sensitive, and making sure furniture can be moved away from walls. Following it properly is what the guarantee depends on.
We set up and bring the rooms up to temperature
Industrial heaters and ducting are positioned to circulate hot air through every part of the room. Wireless probes go into the places bed bugs actually hide — mattress seams, bed frame joints, behind headboards, under carpet edges — so we are measuring core temperature at the harbourage, not air temperature in the middle of the room.
We hold the temperature and work the room
Reaching temperature is not the same as holding it. The technician stays on site for the whole treatment, agitating harbourages so trapped pockets of cooler air are broken up, moving furniture, and watching the probe readings until every monitored point has held above the lethal threshold for long enough.
We cool down, inspect and hand back
The rooms are brought back down, inspected, and you get a written record of what was treated, the temperatures reached and how long they were held. That report is what backs the 60-day guarantee — and what landlords, letting agents and care providers keep on file.
What It Costs
Heat Treatment Pricing, Explained Properly
Heat treatment is priced per room — not by property size, floor area or postcode. The range is roughly £400–£800 per room, and the rate falls as the number of rooms rises, because one visit’s setup, travel and equipment cost is shared across everything treated that day.
In practice that means treating a single bedroom sits at the upper end, and treating several rooms in the same visit brings the per-room figure down considerably. It also means the cheapest thing you can do, if bed bugs have already spread beyond one room, is to treat those rooms together rather than one at a time.
Whatever the number is, you get it before you book and it does not change on the day. For how heat compares with the rest of the UK market — including what general pest control companies charge for spray programmes — see our bed bug treatment cost guide.
Compare
Heat, Steam & Desiccant, or Chemical Spray
We offer all three, and they are not interchangeable. This is the honest comparison.
| Heat treatment | Steam & desiccant | Chemical spray | |
|---|---|---|---|
| Kills eggs | Yes | Over time, as eggs hatch | No |
| Visits needed | 1 | 1 | 1 (early-stage only) |
| Time to resolution | Same day | Weeks | Days, if it works |
| Chemical residue in the home | None | Inert dust in voids | Yes |
| Affected by insecticide resistance | No | No | Yes |
| Written guarantee | 60 days | None | None |
| Price | £400–£800 per room, less per room as rooms rise | From £300 first room, reduced rate per extra room | £175 per visit |
If heat treatment is possible at your property, it is the option we recommend and the only one we guarantee. Where it genuinely cannot be carried out, steam and desiccant dust is a real professional alternative rather than a compromise. Chemical spray is sold honestly as an early-stage option only.
Some properties benefit from heat followed immediately by a residual barrier on the same visit — particularly flats and HMOs where bed bugs keep arriving from next door. That is covered on our combined heat and residual treatment page.
Where It Goes Wrong
Why Bed Bug Treatments Fail
Almost every “the bed bugs came back” story comes down to one of these four.
Sprays and pyrethroid resistance
UK bed bug populations have widespread resistance to pyrethroid insecticides — the active group in most professional sprays and virtually every shop-bought one. A treatment that a resistant population survives is not a cheaper treatment, it is a delay that lets the infestation double.
DIY heat that does not get hot enough
Steam cleaners, hairdryers, tumble dryers and “bed bug heaters” from marketplaces reach surface temperature but not core temperature. Partial heat is actively counterproductive: it drives bed bugs deeper into wall voids and into neighbouring rooms rather than killing them.
Treating one room in a shared building
In a flat, HMO or terrace, bed bugs travel along service voids and shared walls. Treating a single room when the infestation has already spread simply moves the problem next door and buys it time to come back.
Waiting to see if it settles down
A bed bug population roughly doubles every two weeks. The difference between a single-room job and a multi-room job is usually a few weeks of hoping it will go away on its own.
Before We Arrive
Preparing for Heat Treatment
Preparation is the one part of the job that is yours, and it is the part the guarantee depends on. You will get a full written list when you book — you can read it in advance on our heat treatment preparation list.
The short version: remove anything heat-sensitive or pressurised, make sure furniture can be pulled away from walls, and do not start moving infested bedding and clothing around the property before the visit — that is one of the most reliable ways to spread an infestation into a room that did not have it.

Screening at Building Scale
Bed Bug Detection Dogs
In a large building, the hard part is not the treatment — it is knowing which rooms need it. Canine screening narrows a hundred rooms to a short list, each one confirmed by a technician before heat treatment is booked.

Without monitoring, you have no proof.
Most bed bug heat treatments rely on guesswork. We rely on data.
We place temperature monitoring probes in every room – in mattress cores, behind skirting boards, inside furniture joints, and in wall cavities. We track the temperature in real time throughout the entire process. And when we’re done, you receive a comprehensive data report that proves every square inch of your property reached the lethal threshold.
