How Much Does Mice Control Cost in Cambridge?

Mouse control in Cambridge is £260, confirmed before booking, with no call-out fee.

Here is what that buys, and why the trapping is the less important half of it.

Trapping Is the Easy Part

Anybody can put a trap down, and a trap will catch a mouse. What a trap cannot do is tell you why there were mice in the first place, or stop the next ones.

A house mouse gets in through a gap far smaller than people expect. It climbs confidently, it follows pipe runs and cable routes through cavities, and it will travel a considerable distance inside a structure. So the point where you see one is frequently a long way from the point where it came in.

Which is why the survey matters more than the traps. The question is not “where is the mouse” but “where is the hole”.

Where They Get In

• Around pipe and cable entries — under the sink, behind the boiler, where the gas or water main enters
• Air bricks with damaged or missing covers
• Gaps under external doors, especially where a threshold has worn
• Where the floor meets the wall in older properties
• Through a cavity, entered at ground level and travelled upward
• Round soil pipes and waste pipes where they pass through a wall
• Gaps at the eaves and under roof tiles, reached from a fence, a drainpipe or an overhanging branch
• Between adjoining properties in a terrace, which is why a neighbour's problem can become yours

Reading the Signs

Droppings

The most useful evidence there is, because they tell you where the activity is concentrated. Mouse droppings are small and dark, and mice produce a lot of them. Look along skirting, in the back of cupboards, under the sink, behind appliances and in the airing cupboard.

Fresh droppings are dark and soft; old ones are grey, dry and crumble. That difference tells you whether you are looking at a current problem or an old one.

Sounds

Scratching and scurrying in the small hours, usually from a ceiling void, a wall or under the floor. Mice are largely nocturnal, so activity in daylight often means the population is large enough that they are competing.

Damage

Gnawed food packaging, often with the contents spilled. Gnawing at the corners of cupboards and doors. Shredded paper, insulation or fabric used for nesting.

Smear marks

Dark greasy marks along a regular route, where the same run is used repeatedly. These are genuinely useful because they map the route rather than just showing presence.

Smell

An established population has a distinctive musky ammonia-like smell, most noticeable in an enclosed space such as a cupboard or a loft.

What the Treatment Involves

1. Survey. Where the activity is, how extensive it is, and how they are getting in — inside and outside the property.
2. A treatment plan appropriate to the household. What is used and where depends on whether there are children, pets or wildlife concerns, and we discuss that before starting rather than after.
3. Placement in protected locations that non-target animals cannot reach.
4. Follow-up visits to monitor and to remove what has been caught.
5. Proofing advice — the specific gaps, in priority order, and what to fill them with.
6. Confirmation that the activity has stopped before we sign it off.

Proofing: What Actually Works

• Wire wool packed into a gap and sealed — mice will gnaw through expanding foam and sealant on their own, but not through a properly packed metal fill
• Metal or heavy-duty bristle strips at the base of external doors
• Proper air brick covers rather than a rag or a piece of card
• Sealing around pipe and cable entries with a rodent-resistant material
• Cutting back branches and climbing plants that reach the roof
• Making sure the drain and gully covers are intact

Proofing is worth doing properly, and it is worth doing all of it. Mice only need one route, so nine gaps closed and one left open is not ninety per cent of a solution.

What You Can Do

• Store dry food in sealed hard containers rather than in packets
• Clear crumbs and spills, especially behind and under appliances
• Do not leave pet food down overnight
• Keep bin bags off the floor and lids closed
• Clear clutter from the areas where activity is showing, so there is less harbourage
• Take a photograph of any droppings before you clear them — it helps with identification
