Bed bug heat treatment in Glasgow

Heat treatment takes the rooms, and everything in them, hot enough that bed bugs and their eggs die, and keeps them there until probes inside the mattress and the sofa prove the heat got through. It is one long day instead of two or three spray visits, and nothing needs sprayed on the bed.

It costs more. Here is what you get for the money, how it works in an old sandstone flat, and when it is worth it.

When heat is the right call

  • Spray has already failed. If the council, a landlord's contractor or a firm has sprayed and the bites came back, heat is the usual next step.
  • The bugs are in soft furniture. Upholstered headboards, ottoman beds and fabric sofas are hard to spray thoroughly. Heat goes into them.
  • You cannot clear the flat three times. Each spray visit needs the room emptied and bagged. Heat needs it once.
  • Children, pregnancy or pets. Some people would rather not have insecticide on the bed. Heat gives that option, though a residual product is often still used along the skirting.
  • Time matters. Landlords between tenants, short lets and hotel rooms need the room back the next day.

Spray is still a good choice for an early infestation in a single bedroom, found in the first few weeks. It is cheaper by several hundred pounds, and done properly it works. The inspection tells you which situation you are in.

The day, step by step

A one or two-bed flat, start to finish. Bigger homes and HMOs take longer, sometimes two days.

  1. Before the day

    You get a list of what has to come out: aerosols, candles, lighters, medicines, vinyl records, house plants, anything that melts, and pets including fish. Bedding and clothes go through a 60°C wash and a hot dryer and into sealed bags. Clutter stays where it is; the technician wants furniture in place.

  2. Morning, set-up

    Electric heaters and fans come in, and the technician checks the fuse board and which sockets are on which circuit. Temperature probes go inside the mattress, the divan, the sofa cushions and the gap behind the skirting. Smoke detectors are covered for the day.

  3. The heat-up

    The rooms climb steadily, usually over two to three hours. The technician moves fans, opens drawers and turns cushions so the heat gets into the places bed bugs hide rather than just the middle of the room.

  4. The hold

    Once every probe shows the kill temperature, the rooms are held there. Bed bugs and their eggs die quickly at that heat; the hold is what makes sure it has reached the core of the furniture. This is the part that should be logged.

  5. Cool-down and finish

    Heaters off, windows open, rooms back to normal over an hour or two. Many technicians then apply a dust or a residual product along skirting, round pipes and at the party wall, to deal with any bug that wanders in from next door later.

  6. Two to four weeks later

    A check visit. If you have had no new bites and there are no fresh spots, the job is signed off. If there are, the problem room is looked at again.

Heat in a Glasgow tenement

A Victorian or Edwardian tenement flat is a different job from a new-build. Ceilings of three metres or more mean a lot more air to heat. Sash windows and old fireplaces leak heat, so the technician may seal them for the day. Lath and plaster walls, cornicing and timber floors on joists all have voids where bed bugs can sit, and the heat has to soak into them.

The electrics need a look too. Heaters draw a lot of power, and an older flat may have a small number of circuits. A sensible firm checks the fuse board at the survey and plans which heater goes on which circuit. Top-floor flats in a close with no lift mean carrying heavy kit up four flights, which adds time and sometimes a little cost.

Then there are the neighbours. Heat clears the flat it is used in, but it does nothing to the flat across the landing. If bed bugs came through the floor or along the pipes, they can come back the same way. That is why many technicians finish with a residual treatment on the shared walls and ask about the rest of the close. In ex-council blocks and modern flats the same applies through service risers.

What the price should cover

A heat treatment price for a Glasgow flat should be for the whole job, written down. It normally includes:

  • a survey or inspection beforehand, sometimes charged separately and deducted if you go ahead;
  • the treatment day, with probes in the furniture and a record of the temperatures reached and how long they were held;
  • a residual treatment of skirting, pipe runs and other entry points where it is needed;
  • a follow-up check two to four weeks later;
  • a clear statement of what happens if you still have bites after the check.

Typical totals as of October 2026 are £700 to £1,100 for one bedroom and £880 to £1,400 for two. Treating a single room costs £500 to £800, then £300 to £500 for each further room on the same day, which only makes sense when the other rooms have been checked and are clear. Very high ceilings can add £50 to £150. Use the price sheet to work out your own range.

The heat figures come from <a href="https://bpca.org.uk/news-and-blog/everything-you-need-to-know-about-heat-treatments-for-bed-bugs" target="_blank" rel="noopener">British Pest Control Association guidance on heat treatments</a>. The treatment is for trained technicians only; portable heaters and home steamers do not get furniture hot enough for long enough.

Heat treatment questions

  1. How much does bed bug heat treatment cost in Glasgow?

    As a guide, £700 to £1,100 for a studio or one-bed flat, £880 to £1,400 for a two-bed and £1,000 to £1,650 for three bedrooms. Single rooms start around £500 to £800. National figures, October 2026; see the price sheet.

  2. What temperature kills bed bugs?

    Adults and eggs die within minutes at around 50°C and above. Treatments aim to get the inside of the furniture to that temperature and hold it, which means the air in the room runs hotter.

  3. Can a tenement flat be heat treated?

    Usually, yes. The things to check are the electrics (older flats may need heaters spread across circuits), very high ceilings, and getting the kit up the close if there is no lift. A survey sorts that out before the day.

  4. How long do I need to be out?

    Most of a working day for a one or two-bed flat, longer for bigger homes. You can usually come back in the early evening once the rooms have cooled.

  5. Will it damage anything?

    Not if the list of things to remove is followed. Heat can warp vinyl, melt candles and crayons and damage some electronics; they come out or go in a cool room. Normal furniture, mattresses and clothes are fine.

  6. Is heat better than spray?

    Not always. Heat kills eggs in one go and avoids insecticide on beds, but costs two or three times as much. Spray works well on a small, early infestation in an otherwise tidy flat. The fair answer depends on how far it has spread.
