THE CYCLE
Bait treats symptoms. It was never designed to fix anything.
Rodenticide bait works by killing rats that consume it. It does not close entry points, remove harbourage, or address why rats are present in the first place. A new population colonises the same routes and voids within weeks because nothing about the structure has changed. The visit cycle — bait, wait, return — is not a treatment plan; it is a maintenance contract on an unresolved problem.
The structural incentive problem runs deeper: a contractor paid per visit has no financial reason to find and communicate the root cause. The trade as a whole does not routinely offer diagnosis — it offers attendance. This is not necessarily bad faith; it is simply the shape of the market. The consequence is that customers stay customers indefinitely, and the underlying problem is never named.
THE SOURCE
Rats don't appear — they arrive through a route and stay because something lets them.
Three structural factors drive persistent infestations. Entry points: gaps in the building fabric — pipe penetrations, damaged airbricks, joint failures, unpointed cavities — that give rats consistent access regardless of how many are killed. Harbourage: undisturbed void space, insulation, cluttered subfloors, ceiling voids, dense vegetation against the structure — the undisturbed cover that makes a building worth staying in. Food and water access: accessible waste, compost, bird feeders, drainage failures that make the location rewarding. None of these are addressed by bait. Until an entry point is sealed and harbourage reduced, rats will return regardless of how many are killed. A building that has supported a colony for months or years will have established runs, worn access points, and embedded scent trails that actively recruit new animals. The problem is architectural. The solution must be too.
THE PROBLEM
8 in 10 of my customers didn't get a rat problem. They inherited one.
Nobody told them the truth. I will. That's where RatREVEAL starts. The truth will set you free — and living with rats is a prison no one admits to. The trade's answer is bait, stink, flies, repeat. It never ends, so people do the only thing that feels like escape: they sell up and pass the problem on. That's why 8 in 10 of my customers inherited their rats with the house — the last owner never fixed it, because nobody ever told them the truth.
Sellers who have lived through the bait cycle and never received a structural diagnosis have no diagnosis to disclose. The infestation is not listed in the survey. The buyer completes on a house with an active or dormant rat problem embedded in its fabric, often with bait boxes still in the subfloor. The silence is not always deliberate — it is the direct product of a trade that never named the source.
THE INVESTIGATION
A RatREVEAL investigation names what baiting never could.
A bait contractor observes activity and places rodenticide; a RatREVEAL investigation maps the building's entry points, traces established runs, identifies harbourage zones, documents evidence of how long the problem has been active, and produces a written record of findings. The customer leaves with a diagnosis — not just a treatment. They know where the rats are getting in, why the previous baiting did not resolve the problem, and what structural remediation is needed. That diagnosis is also a document: it can be shared with a builder, a solicitor, or a new occupant. It ends the silence.
COMMON QUESTIONS
Questions people ask once they've stopped trusting the bait cycle.
My pest controller has been coming for a year. Why hasn't it worked?
Repeated baiting kills individual rats but leaves the entry points, runs, and harbourage intact. A new population occupies the same structure within weeks. Until the building itself is investigated and the access routes are identified and sealed, the problem will continue regardless of how many visits are made or how much bait is laid.
Could the rats in my house have been there before I moved in?
Almost certainly, if the problem appeared within the first year of ownership. Active infestations leave physical evidence — worn runs, grease marks, embedded scent trails — that persists long after the animals themselves have been baited out. A house that supported a colony for years will have entry routes and harbourage that new occupants inherit without knowing. RatREVEAL investigations regularly find bait boxes, old droppings, and sealed-over entry attempts that predate the current owner's tenure.
Why doesn't my surveyor or estate agent flag this?
Standard building surveys do not include specialist pest inspection. A RICS survey covers the structural condition of the property; it does not involve a thorough investigation of subfloor voids, cavity walls, or drainage runs. Rat activity can be present and active without being visible to a general surveyor. The result is that infestations pass through property transactions undisclosed — not always through deliberate concealment, but through the limits of what a standard survey examines.
Is a RatREVEAL investigation just a more thorough pest control visit?
No. A pest control visit is an attendance: bait is placed or refreshed and the contractor leaves. A RatREVEAL investigation is a diagnostic exercise: the building is examined systematically for entry points, runs, harbourage, and evidence history. The output is a written findings report — not a follow-up appointment. The goal is to produce a diagnosis that is actionable and documentable, not to start a maintenance relationship.
What do I do with the diagnosis once I have it?
The written report names the entry points and structural factors driving the infestation. You can take that directly to a builder or contractor to commission the remediation work. If you are in a dispute with a previous owner or vendor, the report documents the evidence of pre-existing activity. If you are considering selling, a resolved and evidenced problem is far more defensible than an undisclosed ongoing one. The diagnosis ends the guesswork.
