£190 flat, £240 house, £180 proofing. With mice, the proofing is not an optional extra so much as the half of the job that stops it happening again.
Professional mouse treatment costs £190 for a flat and £240 for a house. Pest proofing is a separate £180, covering up to one hour on suitable small holes.
The same prices apply across the whole Harrow area. With mice in particular, the proofing is worth serious consideration — more so than with any other pest we handle.
| Service | Price |
|---|---|
| Mouse treatment – flat | £190 |
| Mouse treatment – house | £240 |
| Pest proofing (up to one hour, suitable small holes) | £180 |
| Flat treatment + proofing | £370 |
| House treatment + proofing | £420 |
A house mouse can pass through a gap far smaller than people expect. The working rule of thumb is that if a pencil fits through an opening, a mouse can get through it — which means the routes into an ordinary building are numerous, small, and almost never noticed.
Nobody looks at the 6mm gap around a waste pipe until something is using it. That is why a treated property with no proofing so often has mice again within a year, and why we mention proofing on a mouse page more insistently than on any other.
Treatment removes the mice. Proofing removes the reason there were mice. With rats you can sometimes get away with only the first. With mice you usually cannot.
Worth understanding, because it explains why waiting is a poor strategy. Mice breed rapidly and reach maturity quickly, so a problem noticed in October and left until Christmas is a materially different job from the same problem dealt with promptly.
It is also why 'we only saw one' is rarely accurate. Mice are small, quiet and largely nocturnal, so a sighting in a living space generally indicates established activity rather than a lone visitor.

View Mouse Control Harrow →Professional treatment of an active mouse problem at your property — the whole property, not a room. Lofts, garages and utility spaces are part of the building and part of the price.
Same price either way — £190 flat, £240 house — but the approach differs and getting it right matters:
| Mouse | Rat | |
|---|---|---|
| Droppings | 3–6mm dark specks | ~15mm, tapered |
| Quantity | Many, scattered widely | Fewer, concentrated |
| Noise | Light, fast skittering | Heavier, with dragging |
| Behaviour | Curious, investigates readily | Wary of new objects |
| Gap needed | Pencil width | Larger, but gnaws to fit |
The behavioural difference matters practically: mice investigate new objects readily, which is why a mouse problem often responds faster than a rat problem.
Read nextRat Control Harrow – How Much Does Professional Treatment Cost? →Rental properties are treated at the same published prices, so a tenant's report can be authorised in one conversation.
For a let, proofing after treatment is usually the sensible economy — £180 once against a second treatment plus another round of tenant disruption a few months later. Mice are the pest most likely to recur in a property where the gaps were never closed.
These are domestic prices. Mice in a food business are a different proposition — documentation frequently matters as much as the treatment — and commercial requirements vary too much for a published figure. Tell us about the premises.
Partly, sometimes. A cat may catch mice in the open but cannot reach the ones nesting inside a wall cavity or under floorboards, and can do nothing about the gap they are using.
Not generally. Tell us about pets and small children when you book, because it affects how and where things are placed.
Usually it means there are more. Mice are nocturnal and secretive, so a daytime sighting in a living space suggests established activity.

No — it is a separate service, though with mice it is more often worth having than with any other pest.

If a pencil fits through it, a mouse generally can.
Usually it means there are more. Mice are secretive and mostly nocturnal.
No. The same published prices apply everywhere we cover.
Partly at best. A cat cannot reach mice nesting in a wall cavity or do anything about the gap they are using.
