Mice Control — Cambourne

Scratching in the Walls at Night in Cambourne: Could It Be Mice?

One question does more work than every description of the sound put together: what time do you hear it?

Mice Control in Cambourne — £260. See the Cambourne service page →

We ask this on every call about a noise, and the answer usually narrows it to one or two possibilities before anything else has been discussed.

The Timetable

When you hear itMost likely
After dark, picking up an hour or two after the house goes quiet, through the nightMice or rats
During daylight, loudest mid-morning and late afternoon, quiet at nightSquirrel
Very early morning, with the dawn chorus, then quietNesting birds
Briefly at dusk, and again before dawnPossibly bats
Only when the heating comes on or goes offPipework and timber, not an animal
Only in windA loose vent, tile, aerial or downpipe
No pattern at all across several nightsWorth keeping a log before concluding anything

Why the Time Is So Reliable

Because it reflects the animal's biology rather than your perception. A description of a sound is subjective and depends on the structure between you and it. Activity hours are not subjective, and they differ sharply between the species that end up in buildings.

The single cleanest separation in this whole subject. Squirrels are diurnal — active in daylight, quiet at night. Mice and rats are nocturnal. If the noise is loudest at two in the afternoon and silent at two in the morning, it is very unlikely to be a rodent of the sort people mean, and no mouse treatment will change it.

How to Keep a Log Properly

  1. Note every instance with the time, over at least four or five nights — a single night is not a pattern.
  2. Note where as precisely as you can: which room, which wall, ceiling or floor.
  3. Note the type: scratching, scurrying, gnawing, thumping, fluttering.
  4. Note how long each episode lasted.
  5. Note anything that changes it — whether it stops when you knock, whether it coincides with the heating.

Five nights of that is more useful to a technician than anything else you can give them, and it frequently answers the question on its own.

The Knock Test

Simple and surprisingly informative. Knock firmly on the wall or ceiling where you can hear it. An animal will usually go silent and then resume after a minute or two. A building will not respond at all, and will carry on doing whatever it was doing.

And If the Pattern Says Rodent

Then go and look for the physical evidence in the part of the building the noise comes from: droppings, gnawing, nesting material, a musky smell, and gaps outside at the corresponding wall or roofline. BPCA put a mouse at a gap of 5mm, roughly the diameter of the eraser end of a pencil, so what you are looking for outside is smaller than seems plausible.

Common Questions

What time of night do mice make noise?
Usually starting an hour or two after the house goes quiet and continuing through the night, in short bursts rather than continuously.
I hear it during the day. Is it mice?
Unlikely. Squirrels are active in daylight and quiet at night, which is the reverse of mice and rats. Daytime noise usually means something else.
How long should I keep a log?
Four or five nights at least. A single night is not a pattern, and the pattern is what separates the possibilities.
Does knocking on the wall tell me anything?
Yes. An animal usually goes quiet and resumes after a minute or two; a building carries on regardless.
