How to Permanently Get Rid of Bed Bugs

The best way to remove bed bugs properly is not one quick spray. It is a step-by-step professional programme: inspect, locate harbourages, vacuum visible bugs and eggs, clean and prepare, steam, apply residual treatment, return around two weeks later and monitor carefully.

“Permanently” means eliminating the active infestation and reducing the risk of return — not pretending bed bugs can never be brought back through travel, luggage, visitors, adjoining flats or second-hand furniture.

Quick answer: can you permanently get rid of bed bugs?

Yes, an active bed bug infestation can be eliminated when the job is carried out properly. The most reliable approach is a structured treatment programme, not a single casual spray or smoke bomb.

The best professional sequence is: inspect, confirm evidence, locate harbourages, vacuum visible bed bugs and eggs, manage laundry, clean and prepare carefully, steam seams and cracks, apply targeted residual treatment, return for a second phase around two weeks later, then monitor.

The EPA describes bed bug control as an integrated process using monitoring, prevention, non-chemical methods and chemical methods where appropriate, rather than one shortcut. Source: EPA.

Important: no pest control company can honestly promise that bed bugs can never be brought back again. The correct aim is to eliminate the current infestation properly and reduce the risk of reintroduction.

What “permanently” really means with bed bugs

Bed bugs are usually introduced into a property from somewhere else. They can come from hotels, luggage, short-let apartments, visitors, second-hand furniture, adjoining flats, HMOs, shared laundry rooms, staff accommodation or untreated belongings.

So “permanent removal” should not be sold as a magic lifetime guarantee. A professional company can remove the active infestation, treat the rooms properly, advise on follow-up and help you reduce future risk. But if bed bugs are brought back six months later from a hotel stay, that is a new introduction, not the original infestation returning.

This honest wording builds trust and prevents unrealistic expectations. The goal is:

Professional goal: eliminate the current infestation, treat hidden harbourages, target eggs and newly hatched nymphs, monitor after treatment, and give clear prevention advice so the chance of future reintroduction is reduced.

Bed bug treatment timeline: what happens and when

StageWhat should happenWhy it matters
First 24 hoursTake photos, avoid moving rooms, bag bedding before moving it, inspect mattress seams and headboard, do not use smoke bombs.Good first actions reduce spread and preserve evidence.
Before treatmentCareful preparation, laundry control, clutter reduction and access to skirting, beds and furniture.Treatment fails if bed bugs are protected by clutter or moved into clean rooms.
Phase 1 treatmentInspection, vacuum reduction, steam where suitable, targeted residual treatment and clear aftercare instructions.Attacks adults, nymphs, eggs and harbourages.
Days 1–7Do not clean treated areas too soon. Keep clean laundry sealed. Continue monitoring.Residual products need time to work and new activity must be observed.
Around 2 weeksSecond phase: reinspection and retreatment of remaining or newly hatched activity.Targets nymphs that may hatch after the first treatment and checks missed harbourages.
Weeks 3–4+Monitoring, interceptors, photo evidence and prevention advice.Confirms whether activity has stopped and reduces reintroduction risk.

Light, moderate or heavy infestation: why treatment plans differ

LevelTypical signsLikely treatment need
Light / earlyOne or two live bugs, light spotting, isolated bed area, few eggs or skins.Fast action, focused inspection, targeted treatment and follow-up monitoring.
ModerateRepeated bites, several harbourages, eggs, cast skins, activity in bed frame or bedside furniture.Thorough treatment of bed, furniture, skirting, laundry and second phase.
Heavy / establishedMany bugs, heavy black spotting, multiple rooms, sofas, wall cracks, clutter, long history.More intensive programme, wider inspection, possible heat advice, repeated follow-up and strict preparation.

The professional step-by-step method to get rid of bed bugs

This is the treatment logic that should be explained to clients. It shows that bed bug control is a detailed process, not a quick room spray.

Step 1: Confirm the infestation

Bites alone are not proof. Look for live bed bugs, pale eggs, cast skins, black faecal spots, blood marks on bedding or insects in mattress seams, headboards, bed frames, sofas and furniture joints.

NHS guidance notes that bedbug bites can be itchy and may appear in a line or cluster, but bed bugs are difficult to spot and hide in furniture, clothing and bedding. Source: NHS.

Step 2: Inspect and locate harbourages

A harbourage is where bed bugs hide, rest, mate and lay eggs. Common harbourages include mattress seams, labels, headboard edges, screw holes, bed frame joints, divan bases, bedside cabinets, skirting gaps, sockets, sofa seams, curtains, luggage and clothing piles.

The most important rule is simple: find the harbourage before treating. Random spraying misses hidden insects.

Step 3: Reduce clutter carefully

Clutter gives bed bugs more hiding places, but moving clutter incorrectly can spread the infestation. Do not carry loose items from an infested bedroom into clean rooms. Bag items first and separate clean, treated and untreated belongings.

EPA preparation advice recommends sealing items in plastic bags when moving them and keeping cleaned items sealed so they remain bug-free. Source: EPA.

Step 4: Vacuum visible bed bugs, eggs and debris

Vacuuming is not a complete treatment, but it can remove visible adults, nymphs, eggs, cast skins and debris before steam and residual treatment.

Use a crevice tool around mattress seams, headboard gaps, bed frame joints, slats, skirting edges, sofa seams and furniture corners. Empty contents into a sealed bag and dispose of them safely. Clean the nozzle or crevice tool afterwards.

Step 5: Laundry control

Bedding, clothing and soft fabrics must be controlled properly. Bag laundry before moving it, wash suitable items at 60°C where the care label allows, and tumble dry on high heat where possible.

NHS advises washing affected bedding and clothing on a hot wash at 60°C and tumble drying on a hot setting for at least 30 minutes. Source: NHS.

Step 6: Steam treatment

Steam is useful for seams, cracks and furniture because it can kill bed bugs and eggs on contact when applied correctly and slowly. It is especially useful for mattress seams, bed frames, headboards, sofas, curtain folds and luggage seams.

EPA says steam can be used on carpets, baseboards, bed frames and furniture, and the steam temperature should be at least 130°F / about 54°C, with care not to scatter bed bugs. Source: EPA.

Step 7: Targeted residual treatment

Residual insecticide can be an important part of a professional programme. It should be applied to selected harbourages and movement routes, not sprayed randomly into the air.

Treatment areas may include bed frame joints, headboards, skirting lines, cracks, crevices, furniture joints, bedside units, sofa frames and wall-floor junctions. BPCA describes residual insecticide spray or powder as a standard professional treatment option for infested premises. Source: BPCA.

Step 8: Mattress encasement and monitoring

Why the second phase after around 2 weeks matters

The second phase is not a small extra. It is often the part that helps turn a reduction job into a successful control programme.

Bed bug eggs can be hidden in seams and cracks. Some may hatch after the first treatment. A second phase around two weeks later allows the technician to check progress, target newly hatched nymphs, inspect missed harbourages, reinforce residual treatment where appropriate and correct any preparation problems.

EPA DIY guidance recommends continued inspection after initial control steps and notes that retreatment may be needed if bed bugs are seen again or if eggs hatch. Source: EPA.

Bon Accord approach: phase one attacks the active infestation. Phase two checks the result, targets hatchlings, treats remaining harbourages and improves the chance of complete control.

What to expect after bed bug treatment

Clients often worry if they notice itching or a bug soon after treatment. Some activity shortly after treatment does not always mean failure, but fresh evidence should be monitored and reported.

After treatmentWhat it may meanWhat to do
Itching continuesOld bite reactions can continue after treatment, and itching is not proof by itself.Check for physical evidence and speak to a pharmacist/GP for skin symptoms.
One bug seen shortly afterMay be disturbed by treatment, but should be reported.Photograph it, keep monitoring and tell the technician before follow-up.
Fresh black spottingPossible ongoing activity.Take photos and arrange reassessment or follow-up.
New nymphs seenEggs may have hatched after phase one.Second phase is important.
No signs for several weeksGood sign, but continue sensible monitoring.Keep prevention advice in place and inspect after travel.

What not to do after treatment

Do not deep clean treated areas immediately unless instructed. Do not move to another bedroom without advice. Do not return unbagged clean laundry to an untreated room. Do not throw away furniture without wrapping and planning. Do not use smoke bombs or extra DIY sprays over professional treatment without asking.

London flats, HMOs, hotels and serviced apartments

London bed bug jobs often involve flats, HMOs, mansion blocks, short-let apartments, hotels and serviced accommodation. These settings can be more complicated because people move luggage, linen, furniture and clothing between rooms, and adjoining units may need consideration.

In flats and HMOs, treatment may need cooperation from tenants, landlords, managing agents and neighbours. EPA notes that bed bug control in multi-family housing needs cooperation from residents and building management. Source: EPA.

Hotels and serviced apartments need fast, discreet action: room inspection, linen control, neighbouring-room checks where appropriate, professional treatment, monitoring and written records. One quick spray is not enough for hospitality settings.

FAQ: How to permanently get rid of bed bugs

The best approach is a professional programme: inspect, locate harbourages, vacuum visible bugs and eggs, manage laundry, steam seams and cracks, apply residual treatment, return for a second phase and monitor afterwards.

A second visit around two weeks later helps target newly hatched nymphs, remaining harbourages and activity that may have been hidden during the first phase.

Vacuuming helps remove visible bed bugs, eggs, cast skins and debris, but it is not a complete treatment. It should be followed by steam, residual treatment and monitoring.

Yes, steam can kill bed bugs and eggs when applied correctly and slowly to seams, cracks and harbourages. It is best used as part of a wider treatment plan.

Professional residual spray can kill bed bugs when applied correctly to harbourages and movement routes. It should not be used as a random room spray.

Old bite reactions can continue, eggs may hatch, or remaining activity may still be present. Take photos of any fresh evidence and report it before the follow-up visit.

Usually you should keep sleeping in the treated room unless your technician tells you otherwise. Moving rooms can spread bed bugs. Follow the re-entry and aftercare instructions for your treatment.

Not automatically. Many mattresses can be treated, encased and monitored. Throwing furniture away without wrapping can spread bed bugs through hallways, lifts and communal areas.

In flats and HMOs it is possible for neighbouring activity or movement of belongings to affect control. This is why inspection, cooperation and monitoring are important in multi-occupancy buildings.

Steam and residual spray do different jobs. Steam gives direct heat treatment to seams and cracks, while residual spray can continue working on selected surfaces. Many programmes use both where appropriate.

Smoke bombs may kill exposed insects but are not reliable as the only treatment because bed bugs hide in cracks, seams and furniture joints.

It depends on infestation level, preparation, clutter, room layout and cooperation. Many professional programmes use at least two phases with monitoring afterwards.

Yes, they can hide in seams, zips, pockets and folded items. Bagging, washing, drying and inspection are important after travel or suspected exposure.

Yes. Bon Accord Pest Control can inspect and treat bed bug problems in London flats, houses, HMOs, hotels, serviced apartments and rental properties.

We thought we had bedbugs but could find no evidence apart from what we thought were bites. I called Bon Accord and Gabriel was there within a couple of hours. He told us we had carpet beetle. Finding the evidence and showing us photos of the skin reaction which was exactly what we had. He advised and returned at a time to suit us to spray which was done thoroughly and efficiently. No sign of the little critters returning. Thank you Gabriel.

Gabriel was absolutely wonderful, a real life saver when I found a mouse by my bed at 10pm. He came in less than an hour and was able to catch the mouse and put my mind at rest so I could go to sleep! Highly recommend, fab service and lovely people.

Gabriel turned up with an hours notice one evening and immediately identified the issued. He works efficiently and professionally throughout with timely follow-ups to ensure the problem was resolved. Once completed he was kind enough to continue to check in to see that the issue had gone. Having had Rentokil previously that spent two years doing very little this was a complete breathe of fresh air and solved the problem in less than two weeks. We are grateful and would highly recommend his services.

We were lucky to have found Bon Accord, they responded very fast to our request and Gabriel was very helpful and informative. He made several visits and did his absolute best until the mice problem we had was gone. Highly recommended.
