Found an Insect—or Only Bites?
Bites alone cannot confirm bed bugs. Send clear photographs of the insect, black spotting, eggs, cast skins, mattress seams and bed-frame joints. We inspect and confirm evidence before recommending treatment.
Bed bugs confirmed

Professional Treatment Starts With Correct Identification
We do not spray blindly because someone has unexplained bites. Every option begins with evidence, inspection and a property-specific plan.
Heat and Dry Steam for Other Confirmed Biting Pests
Heat and professional dry steam can also form part of treatment for other confirmed biting-insect problems where the pest, property and infestation make the method appropriate. Fleas, mites and other insects require different decisions, so we identify the cause before recommending a method or price.
What it is designed to achieve
The service is designed to eliminate adult bed bugs, nymphs and eggs in one complete attendance, usually within several hours. Detailed steam provides direct treatment to suitable accessible seams, folds and furniture joints while controlled heat treats the wider affected area and its contents.
No routine paid second appointment is required. Monitoring and the written guarantee remain in place if qualifying continuing activity is confirmed.
Who chooses it
- Customers wanting no residual insecticide
- Homes with children or pets
- Clients concerned about pesticide residues
- People wanting treatment completed quickly
- Hotels and serviced accommodation
- Properties where a multi-week programme is inconvenient
Inspect and confirm
We locate evidence, assess the affected rooms and identify items or adjoining areas that must be included.
Prepare and protect
Preparation is checked and heat-sensitive belongings are removed or managed according to the written instructions.
Steam detailed areas
Suitable seams, folds, joints and accessible harbourages receive careful direct steam treatment.
Treat the whole area
The treatment space is heated and managed so lethal exposure reaches bed bugs throughout the included areas.
Check and monitor
The technician completes treatment checks and positions monitors where appropriate.
Guarantee the result
The qualifying one-off service receives a written 30-day guarantee.

Two-Phase Bed Bug Treatment
From £289 per phase—£578 for the complete two-phase programme. Suitable for qualifying properties with up to two bedrooms, subject to layout and inspection.
Initial phase
Inspection, physical reduction, professional steam, targeted residual treatment and monitors.
Correct interval
The second phase is normally scheduled 7–14 days later according to evidence and the property.
Follow-up phase
Reinspection, monitor checks and further steam or residual treatment where appropriate.
Why the second phase matters
Direct steam can kill bed bugs and eggs when the required heat reaches them. Eggs or insects protected deep inside inaccessible joints and cracks may not be reached during the first visit. Residual treatment helps control activity as it emerges, while the follow-up allows us to inspect the response before the infestation can recover.
Complete both scheduled phases
Do not stop because sightings fall after phase one. Reduced activity is encouraging, but the guarantee applies after the complete recommended programme and correct aftercare.
Learn more about bed bug eggs and treatment timing.
Three-Phase Residual Bed Bug Treatment
£289 per phase—£867 for the complete three-phase residual-spray programme, covering up to three bedrooms and one living room in a qualifying property. This is the larger phased option for customers who do not choose heat and dry steam.
Phase one: reduce and treat
Evidence is confirmed, harbourages are inspected, monitors are positioned and professional residual treatment is applied to suitable areas.
Phase two: emerging activity
We recheck the principal harbourages and target newly emerged or surviving bed bugs at the correct stage.
Phase three: complete the programme
Monitoring and evidence are reviewed, relevant areas are treated again and final aftercare and guarantee instructions are confirmed.
This option may suit larger homes, landlords arranging a scheduled programme, or properties where heat and dry steam are not selected. Additional rooms, difficult layouts or connected areas are quoted separately.
Treat Adults, Nymphs and Eggs—not Only What You Can See
Bed bugs hide inside narrow furniture joints, screw holes, fabric folds, cracks, skirting edges and other protected spaces close to sleeping or resting areas. A quick spray can reduce visible activity while leaving the life cycle able to continue.
Eggs
Small pale eggs can be attached deep inside protected harbourages. Heat or direct steam can kill eggs when the required exposure reaches them.
Nymphs
Newly hatched bed bugs are small and pale. Phased programmes target them before they mature and reproduce.
Adults
Adults may survive for long periods and move between sleeping areas if rooms or belongings are disturbed.

30-Day Bed Bug Elimination Guarantee*
Every qualifying completed programme includes a written 30-day guarantee. It begins on the day the one-off heat and dry-steam treatment is completed, after phase two of the two-phase programme, or after phase three of the residual programme.
If continuing bed bug activity from the treated infestation is reported and confirmed during those 30 days, Bon Accord will provide any additional inspection and treatment we recommend free of charge—including technician labour and treatment materials.
Elimination
Guarantee*
1. When does the guarantee begin?
For the one-off heat and dry-steam option, it begins when that treatment is completed. For the two-phase and three-phase programmes, it begins after the final scheduled phase has been completed.
2. Is additional guarantee treatment completely free?
Yes. When qualifying continuing activity is confirmed, the remedy is any additional inspection and treatment recommended by Bon Accord at no charge, including technician labour and treatment materials. The guarantee provides remedial service rather than an automatic cash refund.
3. Does one £289 residual visit include the guarantee?
No. £289 is the price for one professional residual-treatment visit. The 30-day elimination guarantee applies after completion of the selected qualifying programme. The complete three-phase residual programme costs £867.
4. Preparation and access
Customers must follow the written preparation instructions and provide reasonable access to all affected and potentially affected beds, frames, headboards, mattresses, divans, bedside furniture, sofas, skirting and other suspected harbourages. If something prevents complete treatment, we will explain the corrective action required.
5. Complete every scheduled phase
Every phase included in the selected programme must be completed at the recommended interval. The guarantee cannot begin after an incomplete or cancelled programme.
6. Keep monitors in position and follow aftercare
Monitoring devices should remain where placed unless we advise otherwise. Residual-treated edges and harbourages must not be washed, scrubbed or vacuumed prematurely, and the affected sleeping area should continue to be used where advised.
7. How should suspected activity be reported?
Contact us within 30 days and provide a photograph, captured specimen or monitor evidence where reasonably possible. Bites alone cannot confirm continuing bed bug activity, but reported bites or unexplained symptoms can still trigger a professional assessment or inspection.
8. What if activity is reported near the end of the guarantee?
A report made within the 30-day period remains valid even if the inspection or remedial appointment takes place after the guarantee period has ended.
9. DIY products and furniture movement
Do not apply smoke bombs, foggers, shop-bought sprays, powders, repellents, essential oils or other pest-control products unless Bon Accord agrees. Beds, mattresses, sofas, clothing and belongings should not be moved into untreated rooms or removed without advice because this can spread activity.
10. New introductions are not covered
The guarantee covers continuing activity from the infestation treated by Bon Accord. It does not cover bed bugs newly introduced through travel, luggage, visitors, new tenants, second-hand furniture, untreated adjoining properties or other external sources. Where the cause is uncertain, we will inspect the available evidence before deciding whether the activity is continuing or newly introduced.
11. Flats and adjoining rooms
Connected or adjacent rooms may require inspection or treatment. Where wider access or coordinated treatment is reasonably recommended, that cooperation is required for the guarantee to apply.
12. Hotels, serviced accommodation and HMOs
High-turnover and multi-occupancy properties may receive site-specific written terms. A 30-day guarantee may apply where all identified affected and adjoining rooms are included and the agreed access, monitoring, housekeeping and reporting procedures are followed.
*The 30-day elimination guarantee applies to qualifying completed programmes and provides free additional inspection and treatment where continuing activity from the treated infestation is confirmed. It is subject to preparation, access, completion, aftercare, monitoring, connected-area and reintroduction conditions.
Vauxhall Case: Successful Treatment After an Expensive Heat Service Failed
An 89-year-old gentleman in a one-bedroom Vauxhall flat had already paid a large international provider for an expensive heat treatment, but bed bug activity continued.
The problem
The client was understandably distressed and concerned about paying again. We did not assume that the earlier service must have reached every harbourage simply because it was described as heat treatment.
Our inspection found continuing evidence around the sleeping area and furniture.
The Bon Accord result
- Harbourages and continuing evidence identified
- Accessible activity physically reduced
- Professional steam applied carefully
- Appropriate treatment and follow-up completed
- Clear aftercare supplied
Client details are anonymised for privacy. Every property is different and outcomes depend on inspection findings, access, preparation and completion of the selected programme.

Signs You May Have Bed Bugs
Look for physical evidence close to places where people sleep or rest. Some people react strongly to bites while others show no visible reaction.
Live insects
Adults are flat, oval and usually brown. Recently fed insects may look darker, redder and more swollen. Nymphs are smaller and paler.
Black spotting
Dark faecal marks around mattress seams, headboards, frames and furniture joints are an important inspection sign.
Eggs and cast skins
Eggs are small, pale and attached inside protected seams or cracks. Pale shed skins may collect near harbourages.
Blood marks
Small marks may appear on bedding after a fed bed bug is crushed, but blood alone is not conclusive.
Bites
Itchy marks may be individual, grouped or linear. They cannot identify the pest without supporting physical evidence.
Typical hiding places
Mattress piping, frame joints, screw holes, divans, bedside furniture, sofas, curtains, skirting and luggage.
Preparation and Aftercare
Heat and residual programmes require different preparation. We send instructions specific to the selected treatment and property.
Before treatment
- Bag bedding before carrying it through the property
- Wash suitable fabrics at 60°C and hot tumble-dry where appropriate
- Reduce clutter without moving it into unaffected rooms
- Provide access to beds, frames, furniture and skirting
- Tell us about every affected room and previous treatment
- Follow heat-sensitive item, pet and aquarium instructions
After treatment
- Return only when the technician advises
- Leave residual-treated edges undisturbed until advised
- Continue using the affected sleeping area where instructed
- Do not use additional DIY products
- Keep monitors in position
- Photograph and report physical sightings promptly

Bed Bug Treatment London FAQs
Prices, treatment methods, visits, preparation and guarantee terms explained before you book.
How much does bed bug treatment cost?
Professional residual treatment starts from £289 per visit. The complete two-phase dry-steam and residual programme costs £578. The three-phase residual programme costs £867 for up to three bedrooms and one living room. One-off chemical-free heat and dry steam starts from £789 for two rooms. Larger or complex properties are quoted after assessment.
Does the £289 residual treatment include the elimination guarantee?
£289 is the price for one treatment visit. The 30-day elimination guarantee begins after completion of the selected qualifying programme. The complete three-phase residual programme costs £867.
What is your fastest bed bug treatment?
The combined heat-and-dry-steam service is the fastest complete option. It is designed as one attendance, usually completed within several hours when the property has been prepared correctly, and uses no residual insecticide.
What rooms does the £789 treatment include?
The starting price covers two rooms total: either two bedrooms, or one bedroom and one living room. Each additional room costs extra, and larger, heavily furnished or complex properties require an individual quotation.
Does heat and dry steam kill bed bug eggs?
Yes, when the required heat exposure reaches them. Controlled heat treats the wider area while direct professional steam targets suitable accessible seams, folds and joints.
Are chemicals used during heat and dry steam treatment?
No residual insecticide is applied as part of the chemical-free heat-and-dry-steam option.
Is one heat-and-dry-steam treatment enough?
The service is designed and sold as one complete planned treatment. No routine paid second appointment is required. Qualifying continuing activity during the guarantee period receives the additional treatment recommended by Bon Accord free of charge.
Why does the steam-and-residual option need two phases?
Eggs or insects protected inside inaccessible areas may not be reached directly during the first visit. Residual protection and a correctly timed second phase target emerging or surviving activity.
Why does residual-only treatment need three phases?
Residual insecticide does not directly penetrate every protected egg. Three scheduled phases provide repeated inspection and treatment across the bed bug life cycle.
How long is the guarantee?
Every qualifying completed programme carries a written 30-day guarantee. It begins when the one-off heat and dry-steam treatment is completed or after the final scheduled phase of a multi-visit programme.
Are additional guarantee treatments free?
Yes. When qualifying continuing activity is confirmed, additional treatment recommended by Bon Accord is free, including technician labour and treatment materials.
Is the guarantee a refund promise?
The guarantee remedy is further professional inspection and treatment under the written terms. It is not automatically a cash-refund promise.
Is chemical-free treatment suitable for homes with children or pets?
The heat-and-dry-steam option leaves no residual insecticide treatment. People and pets must leave during the service and return only when advised. Tell us about medical, mobility or sensitivity concerns before booking.
Do I need to throw away my mattress?
Usually not. Many mattresses, frames and sofas can be treated. Moving or discarding furniture without proper containment can spread the infestation.
Can bed bugs live in sofas?
Yes. Sofas and upholstered chairs can become harbourages where people regularly sit, rest or sleep.
Can bed bugs spread between flats?
Yes. They can spread through belongings, connected rooms, cracks, service routes and furniture movement. Adjoining areas may require inspection.
Can you treat after another company failed?
Yes. Tell us exactly what was used, when it was applied and which rooms were treated. Previous treatment information helps us select the correct method.
How quickly can you attend?
Our phone is answered 24/7. Same-day and urgent London appointments may be available depending on property preparation, location and technician availability.
Do you treat hotels and Airbnb properties?
Yes. We provide discreet inspection, heat-and-dry-steam treatment, phased programmes, monitoring and reporting for commercial accommodation.
