How Much Does It Cost to Treat Bed Bugs Professionally?
When bed bugs appear, cost is usually the first concern. The honest answer is that prices vary with property size, layout, clutter, and the method used. In the UK, heat treatment often looks dearer upfront than chemicals, yet it routinely ends up cheaper overall because it removes the infestation in a single visit and prevents long, drawn-out return visits.
As heat-treatment specialists, ThermoPest focuses on evidence-based eradication that works across all life stages, including eggs. Below, you’ll find real-world UK pricing ranges, the science that drives those costs, and practical ways to keep your spend efficient without risking spread.
What people believe vs reality
- Belief: “A quick spray is the cheapest fix.” Reality: Chemical-only programmes often require 2–3 visits over several weeks and can miss resistant eggs or insects in inaccessible voids, making the final cost higher.
- Belief: “Heat is only for severe cases.” Reality: Professional bed bug heat treatment is recommended at any stage because it destroys eggs and active bugs in one structured operation.
- Belief: “DIY will save money.” Reality: Most DIY attempts scatter bugs, create cold spots, and prolong the problem—adding laundry, replacement, and re-call costs.
What actually drives the price
- Property size and complexity: More rooms, dense furniture, and built-in voids take longer to heat or treat and need more equipment.
- Level of infestation: Light, moderate, or heavy activity changes time on site and the monitoring needed to confirm clearance.
- Access and scheduling: High floors, restricted parking, and out-of-hours work can add labour and logistics costs.
- Preparation quality: Good prep shortens treatment time and reduces risk of cold spots. See preparing your home for treatment.
Typical UK costs (realistic ranges)
- Inspection and survey: £60–£150 (often credited if you proceed).
- Domestic heat treatment (whole property):
- Studio/1-bed flat: ~£700–£1,200
- 2–3 bed home: ~£1,000–£1,800
- Larger or complex layouts: ~£1,800–£3,000+
- Domestic chemical programmes:
- Per visit: ~£150–£350 depending on size and rooms
- Typical 2–3 visit programme: ~£400–£1,000 total
- Additional monitoring/clear-down often required
- Commercial (hotels, HMOs, care):
- Single room heat: ~£350–£700
- Suites/adjacent rooms or rapid-turnaround work: ~£700–£1,200+
- Multiple rooms/floors: priced after survey (volume efficiencies apply)
- Hidden/indirect costs to consider: laundry at 60°C, mattress encasements, staff downtime, room closure, reputational risk, and the risk/cost of re-treatment.
While chemical quotes can start lower, the total cost of ownership often favours heat because it shortens the timeline to clearance and reduces the chance of further visits. See why heat treatment works better than chemicals for a science-led comparison.
Science-backed facts that affect cost and success
- Lethal temperatures: Bed bugs and their eggs die when their core temperature is held within a lethal band for long enough. Learn what temperature kills bed bugs and why hold time matters.
- Thermal penetration: Heat must reach into mattress seams, furniture frames, skirting voids, and sockets—areas sprays and DIY steam rarely reach consistently.
- Resistance: Insecticide resistance is well documented; eggs are particularly resilient, which is why chemical-only programmes often need multiple visits.
Common mistakes that make bed bugs cost more
- Moving infested items to other rooms, spreading bugs to new harbourages.
- Overusing shop sprays or foggers, which push insects deeper and create avoidance behaviour.
- Insufficient prep—overfilled cupboards, under-bed clutter, or unbagged laundry prevent proper heat penetration.
- Stopping early—declaring victory after a few quiet days and skipping confirmation monitoring.
Practical, safe steps to reduce cost
- Follow structured prep: bag and seal clothing/linen; declutter sensibly; isolate beds from walls. Start with preparing your home for treatment.
- Launder textiles at 60°C and tumble-dry hot where fabric allows.
- Use encasements on mattresses and divans after clearance to reduce future harbourage.
- Plan a short, focused monitoring period after treatment (interceptors, visual checks) to confirm success without panic moves.
Why heat treatment is the superior solution
Cold spots removed
Professionally designed heaters, air movers, and targeted nozzles drive heat into typical cold spots (bed joints, socket voids, skirting channels). Effective air circulation prevents “safe pockets” where eggs would otherwise survive.
Sustained lethal temperature
Success isn’t just hitting a peak—it’s holding target temperature long enough for thermal death. Our teams engineer the room to keep surfaces and voids within the lethal band for the required dwell time.
Sensors and monitoring
Multiple wireless sensors confirm temperatures across the space, so technicians can correct imbalances in real time. See our bed bug heat treatment process to understand how we validate each stage.
All life stages killed
Proper heat kills eggs, nymphs, and adults in one controlled operation, reducing the need for return visits. This is the main reason the overall cost-to-clear is usually lower than drawn-out chemical programmes.

FAQ’S
Question: Is heat treatment more expensive than chemicals?
Answer: Upfront, heat can cost more than a single chemical visit, but the total spend is often lower because a well-run heat treatment clears all life stages in one day. Chemical-only programmes usually need 2–3 visits over weeks and can struggle with eggs or resistant populations. This prolongs disruption, monitoring, and potential rework. A safe tip: compare total programme cost and time-to-clear, not just the first visit price—in professional practice heat wins on speed and completeness.
Question: How are bed bug treatment quotes calculated?
Answer: Quotes reflect survey time, property size, room count, contents density, access, and whether evening/weekend work is needed. Heat pricing also covers specialised heaters, power management, air movers, and temperature sensors to prevent cold spots. Severe or multi-room infestations need more equipment and dwell time, which raises cost. A safe tip: share floor plans and photos before the visit to get an accurate fixed quote—in professional practice this prevents scope creep.
Question: Do I ever need more than one heat treatment?
Answer: Most domestic cases clear with a single, properly managed heat treatment because lethal temperatures are held long enough to destroy eggs and active bugs. A second visit may be advised if new activity is introduced later (re-introduction via luggage or furniture) rather than true re-infestation from survivors. Targeted follow-up inspections and interceptors help confirm clearance quickly. A safe tip: keep suitcases isolated and launder travel clothes at 60°C—in professional practice, monitoring confirms success rather than guesswork.
Question: Why do some treatments fail or seem to ‘come back’?
Answer: Failures usually stem from cold spots, inadequate dwell time, insecticide resistance, or new bugs being brought in after treatment. If you still see bites weeks later, it may be re-introduction, not survivors from the original job. Structured monitoring and a brief confirmation inspection separate the two. A safe tip: use bed interceptors for two weeks post-treatment and avoid moving beds until confirmed clear—in professional practice, documented temperatures and checks prevent ambiguity.
Question: What can I do to keep costs down without risking spread?
Answer: Focus on preparation: reduce clutter, bag textiles, and make bed frames accessible so heat flows into typical harbourages. Avoid shop foggers and random spraying, which scatter bugs and create hard-to-treat pockets. After treatment, keep a simple monitoring routine to confirm success quickly and avoid unnecessary recalls. A safe tip: follow the provider’s written prep list exactly—in professional practice, good prep shortens job time and ensures full thermal penetration.
