Heat treatment for bed bugs in Bristol

Heat treatment warms a room, and everything in it, past the point bed bugs and their eggs can survive, then holds it there while the heat soaks into mattresses, sofas and skirting. One long visit replaces a course of sprays, with no insecticide on the bed.

It is the dearer method, and it suits some Bristol homes much better than others. This page sets out the day, the price and the cases where it is worth it.

Visits: One, plus a check
On site: 6 to 9 hours
Target: 50°C+ held
From: £480 to £800 a room

In brief

Kills eggs as well as adults, so there is no waiting for hatchlings.
Best where a spray course has already failed, or where bugs are in a sofa or divan.
Leaves no residue behind, so it is often paired with a light spray at the skirting.
Top-floor flats in converted houses need planning: heaters and power on the stairs.

How a heat treatment day runs

Times are for a two-bedroom flat. A larger house or an HMO can run into the evening.

Arrival and set-up, about 8:30
The technician walks the rooms, checks the fuse board and plans where the heaters and fans go. Wireless temperature probes are pushed into the mattress, the sofa and the gaps at the skirting, the places that heat up last.
Warming the rooms, two to three hours
Electric heaters bring the air to around 55 to 60°C while fans keep it moving. Drawers are opened, cushions stood on end and wardrobes left ajar so the heat reaches inside.
The hold, two hours or more
Once the coolest probe passes the target, the temperature is held. This is the part that kills eggs tucked deep in seams. The technician moves fans and turns furniture as the readings come in.
Cooling and finishing, an hour
Rooms are opened up and cooled. Many technicians then apply a dust or residual product along skirting and wall voids, which protects against bugs coming back from a neighbouring flat.
Check visit, two to three weeks later
A look at the beds and any monitors left behind. Fresh signs at this stage usually mean a missed spot or a source next door, and a sound firm treats that at no extra cost.

Why heat works when it is done properly

Laboratory work on bed bug heat tolerance found that adults die after an hour or so at around 45°C, while eggs need about 48°C held for several minutes, and higher for a short exposure (Kells and Goblirsch, 2011). The catch is that a thermostat on the wall tells you nothing about the inside of a mattress. That is why a good job is measured with probes in the furniture, and timed from the moment the coolest one reaches the target.

The British Pest Control Association describes heat as effective when it is run by trained technicians with the right kit, and warns that partial heating can simply drive bugs into cooler spots. Domestic fan heaters, hairdryers and hot cars are not a substitute.

Heat in Bristol homes

Bristol housing changes how a heat day is planned more than people expect.

Converted Victorian houses: Much of Redland, Cotham, Bishopston and Montpelier is tall terraces split into flats. Heat treats your flat well, but bugs can sit in the floor void or the flat below. Ask whether the neighbours have bites before you book, and expect a dust treatment at shared walls.
Top floors without a lift: Heaters are heavy and need several circuits. In a third-floor Clifton flat the firm may bring its own generator or split the job into two days. Tell them the floor and parking on the form so the price is right first time.
Georgian rooms and high ceilings: Big rooms with high ceilings and sash windows lose heat fast, so they take longer and cost more to treat than a modern bedroom of the same floor area.
Purpose-built blocks: In the city centre and Harbourside, newer blocks have smoke heads and heat detectors. These are covered or isolated with the building manager beforehand, so book through them if you rent.

Heat or a spray course?

	Heat	Spray course
Visits	One long day and a check	Two or three, about 14 days apart
Eggs	Killed on the day	Mostly survive; the next visit catches hatchlings
Leftover protection	None unless a residual is added	A residual that keeps working for weeks
Preparation	Heat-sensitive items out; little bagging	Wash and bag bedding and clothes
Two-bed flat	£900 to £1,450	£340 to £660

Many specialists combine the two. Spray-course prices are covered on the price estimator.

What to do before the day

Remove what heat can damage: Aerosols, lighters, candles, vinyl records, oil paintings, plants, medicines, chocolate and anything with a lithium battery. The firm gives you a full list; keep it with the keys.
Do not move the beds: Leave furniture where it is and keep sleeping in your own bed until the day. Moving to the sofa spreads bugs to a fresh room.
Wash what you are taking out: Anything leaving the flat goes through a 60°C wash and a hot dryer, as the NHS advises, and is then sealed in a bag.
Pets and fish: Pets stay elsewhere for the day. Fish tanks need specialist advice, so mention them when you send the request.

Heat treatment questions

How much is bed bug heat treatment in Bristol?

As a guide, £480 to £800 for one room, £720 to £1,150 for a one-bed flat and £1,050 to £1,750 for a three-bed house, VAT included. Access, parking and the number of rooms move it most.

Is one heat treatment enough?

Usually, when probes show every hot spot reached the target. A check visit two or three weeks later confirms it. Where a neighbouring flat has bugs, a second treatment or a residual barrier may be needed.

Will the heat damage my things?

Furniture, clothes, mattresses and most electronics are fine at the temperatures used. Items that melt, burst or spoil come out first, and the technician watches the readings throughout.

Can I stay in the flat during the treatment?

No. Plan to be out for the whole day, with pets. You can sleep there the same night once the rooms have cooled.

Is heat safer than spraying for children?

There is no insecticide on the bed, which is why many families choose it. Where a residual is used afterwards it goes in cracks and along skirting, not on mattresses.

Does it work in a flat in a converted house?

It treats your flat completely. Whether the problem stays gone depends on the other flats, which is why the firm will ask about neighbours and may treat the shared walls and floor gaps.
