[ Every life stage ]
What a single heat cycle actually kills
Bed bugs survive sprays by hiding, breeding and hatching out of reach. Heat removes the hiding place — the whole room becomes lethal at once.
Adults
Killed on contact once core temperature passes the lethal threshold.
Nymphs
Every juvenile stage cleared in the same single heat cycle.
Eggs
Heat penetrates mattress seams and voids where sprays never reach eggs.
Resistant strains
Heat is a physical kill — resistance to insecticide makes no difference.
- Sustained lethal core temperature
- 50°C+Sustained lethal core temperature
- Whole-room treatment, no spray cycle
- 1 visitWhole-room treatment, no spray cycle
- Chemicals or residue left behind

The five stages of a heat day
Same sequence on every job, from a single studio flat to a five-bedroom house.
- 01
Inspect
Survey confirms species, spread and every harbourage point before a heater is switched on.
- 02
Seal
Rooms are sealed and heat-sensitive items removed so temperature holds evenly, edge to edge.
- 03
Heat to 56°C
Industrial heaters and circulation fans drive the whole room past the lethal threshold.
- 04
Verify
Wireless probes inside mattresses and wall voids log the hold time — you get the readout.
- 05
Guarantee
Aftercare pack, prevention advice and a 6-month written guarantee on the treated rooms.
Why 56°C, and why it has to hold
Bed bugs do not die the instant a room feels hot. Each life stage has its own lethal threshold, and heat has to soak through mattresses, bed frames and skirting voids to reach them. We overshoot the minimum and hold it — that margin is the difference between a treatment and a guarantee.
- 45°C
- Nymphs dieJuvenile stages fail within minutes
- 48°C
- Eggs dieThe stage chemical sprays routinely miss
- 56°C
- Our target holdSustained across the whole room, logged
[ Why heat ]
Sprays manage an infestation. Heat ends it.
UK bed bug populations are increasingly resistant to residual insecticides. There is nothing to become resistant to with heat.
| Compared on | Heat treatment | Chemical spray |
|---|---|---|
| Kills eggs | Yes — in the same visit | No, eggs commonly survive |
| Visits needed | Usually one | Two to four, weeks apart |
| Insecticide resistance | Irrelevant — physical kill | A growing UK problem |
| Chemical residue | None | Residual deposits in the room |
| Reaches wall voids & frames | Yes — the whole room is heated | Only treated surfaces |
| Back in the room | Same day, once cooled | After each spray dries |

Bed bugs: in-depth advice
Heaters, air movers and wireless probes positioned before a heat treatment begins.
Inside a heat treatment
One controlled visit. Every life stage, including the eggs.
We bring the room to a lethal, evenly held temperature using professional heaters, air movers and wireless probes — then hold it long enough to reach bugs and eggs inside frames, skirting and sockets.
Temperatures are logged live throughout, so the treatment is evidenced rather than assumed. No residual chemical smell, and most rooms are usable again the same day.

What a bed bug survey entails
A bed bug survey is a thorough, room-by-room inspection carried out by a trained technician to confirm the presence, extent, and location of an infestation. During the visit, we examine mattresses, bed frames, headboards, skirting boards, electrical outlets, and soft furnishings using torches, magnification tools, and specialist detection equipment where needed. We look for live bed bugs at every life stage, shed skins, faecal spotting, and eggs clustered in cracks and crevices. The technician also identifies harbourage points, assesses the level of clutter, and checks adjoining rooms that may have been affected. At the end of the survey, you receive a clear written report outlining the findings, the recommended heat treatment plan tailored to your property, preparation instructions, and a fixed-price quote — with no obligation to proceed.
Signs of bed bugs
Bed bugs give themselves away long before you see one crawling. Check mattress seams, piping, bed frames and headboards for these tell-tale signs.
- Small dark faecal spots along mattress seams, piping and bed frame joints
- Shed skins (pale amber shells) left behind as nymphs grow
- Tiny blood smears or rust-coloured stains on sheets and pillowcases
- Live bugs — flat, oval and reddish-brown, roughly 5 mm long
- Clusters of pale, rice-grain-shaped eggs tucked into cracks and crevices
- Itchy bites in lines or clusters on skin exposed during sleep
- A sweet, musty odour in heavily infested rooms

Disclaimer & important information
Please read carefully before booking your heat treatment.
- Heat treatment effectiveness depends on proper preparation. Items not removed or rooms not decluttered may shield bed bugs from lethal temperatures.
- We cannot guarantee 100% eradication in properties with structural issues (e.g. severe draughts, open cavity walls, or inaccessible voids) that prevent uniform heat distribution.
- Re-infestation from external sources (adjoining flats, shared housing, or reintroduced infested items) is not covered under our standard guarantee.
- Our guarantee covers follow-up treatment only within the stated period and does not extend to consequential damages, accommodation costs, or replacement of personal property.
- To activate the 6-month bed bug guarantee we require time-stamped video evidence of live bed bugs before we will carry out a follow-up visit.
- All treatment decisions are made at the discretion of the attending technician based on site conditions and health & safety assessments.
