Bed Bug Detection Dogs
Screening a whole building for bed bugs by eye is not realistic. A trained detection dog can sweep a care home, hotel, student block or HMO room by room in hours — so you find out where the problem actually is, confirm it, and treat only the rooms that need treating.

Why It Changes Things
The Problem With Inspecting a Whole Building
In a house, finding bed bugs is a matter of looking properly in a handful of places. In a sixty-bed care home or an eighty-room hotel, the same job is arithmetic that does not work: nobody is stripping every bed, every week, on the off chance.
So what usually happens instead is that a building waits for a complaint — by which point the population has been doubling every couple of weeks, often for months, and has had every opportunity to move along a corridor. Canine screening is the only practical way we know of to check a building at that scale before someone complains.
A building gets screened in hours, not days
A handler and dog work along a corridor at walking pace. A care home or hotel floor that would take a technician a full day to strip and inspect properly can be swept in a fraction of the time, room by room, without turning out every bed.
You stop treating rooms that do not need it
The expensive mistake in a large building is not treatment — it is treating the wrong rooms, or blanket-treating a whole wing because nobody knows where the problem actually is. Screening turns that into a short list.
It finds problems people cannot report
In care settings, residents with dementia or limited mobility often cannot report bites, and marks get attributed to something else for weeks. A screening sweep does not rely on anyone noticing.
It gives you something to show
You get a room-by-room record of what was screened, what alerted and what was confirmed. That is what a CQC inspector, an environmental health officer, a franchise auditor or an unhappy guest actually wants to see.
The Evidence
How Accurate Are Detection Dogs, Really?
This is worth being straight about, because the industry is not always.
In controlled conditions, dogs are extremely good. A University of Florida study published in the Journal of Economic Entomology found that trained bed bug detection canines located live bed bugs with 98% accuracy in hotel-room experiments. The same work found dogs could discriminate bed bugs from ants, cockroaches and termites with a 97.5% correct indication rate and no false positives, and could tell live bugs and viable eggs apart from dead bugs, cast skins and faeces with a 95% indication rate.
Pfiester, Koehler & Pereira (2008), Journal of Economic Entomology 101(4)In real, occupied buildings, results are more variable. A later study assessed eleven working canine teams in naturally infested apartments and reported a mean detection rate of 44% and a mean false-positive rate of 15%, with wide ranges on both — and, importantly, significant variation for the same team on different days.
Cooper, Wang & Singh (2014), Journal of Economic Entomology 107(6)Both of those things are true at once, and the gap between them is the whole point. A detection dog is an outstanding screening tool — it narrows a hundred rooms down to a handful, faster than any other method available. It is not a diagnosis, and any company telling you it is has an interest in you not asking follow-up questions.
So we use it as a screen, not as a verdict. The dog tells us where to look. A technician confirms what is actually there. Nothing gets treated, and nothing gets billed as treatment, on an alert alone.
How It Works
From Scoping Call to Clear Building
A short scoping call
We establish the building type, how many rooms are in scope, whether there is a known problem or this is routine screening, and what access looks like. Canine screening is quoted per building, not per room, so this is where the price is fixed.
The screening sweep
The handler and dog work the rooms in scope with minimal disruption. Rooms do not need stripping first, residents and guests do not need to be moved out for the sweep itself, and it is done quietly — no vans full of equipment in the car park.
Visual confirmation of every alert
Where the dog indicates, a technician inspects properly — mattress and divan seams, bed frame joints, headboard fixings, skirting and furniture. Nothing is booked for treatment on an alert alone.
Targeted treatment where it is confirmed
Confirmed rooms go forward to heat treatment, which kills adults, nymphs and eggs in a single visit. In buildings where heat cannot be used in a particular room, steam and desiccant dust is the alternative.
Re-screen to prove it is clear
A follow-up sweep after treatment is how you close the file — and it is the part that matters most if you are answering to an inspector, an insurer or a guest who is threatening a review.
Compare
Canine Screening vs Visual Inspection
They are not competing methods — they do different jobs, and a good programme uses both.
| Canine screening | Visual inspection only | |
|---|---|---|
| Speed across a large building | Hours | Days |
| Rooms that can realistically be covered | All rooms in scope | Usually a sample, or only reported rooms |
| Room preparation needed first | None | Beds stripped, furniture moved |
| Finds problems nobody has reported | Yes | Only by chance |
| Confirms what is actually there | No — needs visual confirmation | Yes |
| Best used for | Screening at scale, and proving a building is clear | Confirming and scoping a known problem |
Confirmed rooms get the 60-day guarantee
Screening finds the rooms. Heat treatment clears them in a single visit, killing adults, nymphs and eggs together — and carries our written 60-day guarantee.

What a Detection Dog Cannot Do
We would rather you knew this before you booked than after.
An alert is not a diagnosis
A dog indicates the presence of an odour. It cannot tell you how many bugs there are, whether they are alive, or whether you are smelling a problem that was treated last year. That is why every alert we act on is visually confirmed first.
Performance varies with conditions and with the day
Field research on teams working occupied flats found not just lower detection rates than the laboratory figures, but significant variation between the same team on different days. Heat, airflow, clutter and fatigue all matter.
It does not replace treatment, and it does not replace looking
Screening tells you where to look. A technician still has to open the bed frame and confirm it, and heat treatment still has to do the killing. Anyone selling a dog as an alternative to inspection is overselling it.
Blanket screening on its own is not a programme
One sweep is a snapshot. For a hotel or care home the value comes from screening on a schedule, or on triggers — a reported bite, a new admission, a room that keeps generating complaints.
Who It Suits
Where Canine Screening Pays for Itself
The value scales with the number of rooms and with how expensive a missed room is.
Care homes — the strongest case of all. Residents may not be able to report bites, rooms cannot be emptied casually, and a single undetected room can seed a wing through shared laundry. Screening also gives you a documented, room-by-room position to show an inspector.
Hotels and guest houses — where the real cost of bed bugs is not the treatment, it is the review. Screening between changeovers lets you find a room before a guest does, and re-screening gives you a defensible answer when someone claims they were bitten.
Student accommodation — the summer changeover window is exactly the right time to sweep a block: rooms are empty, the whole site can be screened at once, and anything found can be treated before the new intake arrives.
HMOs, blocks of flats and portfolio landlords — where bed bugs travel between units along service voids and shared walls, and where treating one flat repeatedly is usually a sign that the neighbouring one has never been checked.
