£190 for a flat, £240 for a house, £180 for proofing. Which one applies, what each covers, and why proofing matters more for mice than for almost anything else.
Professional mouse treatment costs £190 for a flat and £240 for a house. Pest proofing is a separate service at £180, covering up to one hour on suitable small holes.
These are our standard published prices — you do not need to make an enquiry to find out what treatment normally costs.
Most people find mouse evidence before they ever see a mouse — droppings behind a kettle, a gnawed cereal packet, a scratching noise in a ceiling void at two in the morning. And the first question is almost always the same one.
Our answer is on this page rather than behind a contact form. £190 for a flat, £240 for a house, and suitable small-hole proofing separately at £180 for up to one hour.
| Property / 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 |
The flat price covers professional mouse treatment in a flat. Flats have a particular complication with mice: they are rarely a single-property problem. Mice move readily through service voids, riser cupboards, ceiling spaces and the gaps around pipework that run between units.
That does not change what your own treatment costs, but it is worth knowing early — particularly if you are a tenant, because access to communal areas is usually something only a landlord or managing agent can arrange.
The house price reflects a larger property: more rooms, more ground-floor perimeter, usually a loft, often a garage or shed, and more potential routes between outside and inside.
Proofing is separate, and with mice it is more often worth having than with almost any other pest. A house mouse can pass through a gap that looks far too small to matter — the usual rule of thumb is that if a pencil fits, a mouse can get through.
Our proofing service is £180 for up to one hour on suitable small holes.

View Mouse Control Harrow Weald →The two get confused constantly, and it matters. Mouse droppings are small dark specks, roughly the size of a grain of rice; rat droppings are noticeably larger and more tapered. Mice tend to leave many droppings scattered widely, because they defecate almost continuously as they move.
Rat treatment happens to cost the same in a flat and slightly more context in a house, but the approach differs and misidentifying the pest wastes a visit.
Read nextRat Control Harrow Weald – How Much Does Professional Treatment Cost? →Common signs, roughly in the order people notice them:
One dropping is worth watching. Several, or any that return after you have cleaned up, is worth acting on — mice breed quickly and a small problem does not stay small for long.
Kitchens and food-storage areas are where people look, but the evidence is often somewhere less obvious: under kitchen units, behind or beneath appliances, in an airing cupboard, in a loft, or in a garage or shed attached to the house.

For a let, proofing after treatment is usually the sensible economy — £180 once tends to cost less than a second treatment plus another round of tenant disruption a few months later.
Seeing one mouse indoors usually means there are more. Mice are small, quiet and mostly nocturnal, so a daytime sighting in a living space generally indicates established activity rather than a lone visitor.
Sometimes, partly. A cat may catch mice in the open but will not reach the ones nesting inside a wall cavity or under floorboards, and cannot do anything about the gap they are using to get in.
They can, in small numbers, well placed. The difficulty is that most people place them in the open rather than along the walls mice actually travel, and stop after a few days.
