Scratching in the Walls at Night in Saint Ives: Could It Be Mice? – Practical Local Guide

This comes up often enough to be worth addressing properly. The pest control part is straightforward. The rest of it is about a household getting through a fortnight.

First, the Reassurance That Is Actually True

• Mice do not come out to interact with people. They avoid us, and they are active when a room is quiet and still
• They are in the void, not the room. A wall cavity or a ceiling void is a separate space from the bedroom
• They are not going to get into a bed. This is the specific fear children have and it is worth addressing directly
• They are small. Showing a child what a mouse actually is, in a picture, is frequently more reassuring than not talking about it
• It is temporary, and saying when something is being done about it helps a great deal

Practical Things That Help With Sleep

• A fan or white noise in the room. The most effective single thing, and it works from the first night
• Moving the bed away from the affected wall, even by a foot or two
• Sleeping elsewhere for a few nights, which is a perfectly reasonable answer and not a failure
• Keeping the door shut, which helps some children and not others
• A nightlight, because the fear is usually of the dark and the unknown rather than of a mouse

No Food in the Bedroom

Worth mentioning without making it anybody's fault. Snacks, crumbs and wrappers in a bedroom — under a bed, in a drawer, in a school bag — are a genuine draw, and clearing them is both useful and something a child can help with, which tends to help with the worry as well.

The Pest Control Part

• Tell us there are children in the household and their ages, at the point of booking. It changes what we use and where it goes
• Everything goes in tamper-resistant housings, secured and placed out of reach in voids and behind fixed equipment — never loose in a room
• Where a non-rodenticide approach is right, we will say so and work with it
• Everything is recorded and removed at the end of the job
• We will tell you what to expect, including that the noise may continue for a few days

And the Honest Timescale

Activity usually reduces over the first week rather than stopping on the day, and the job finishes when a return visit confirms it has stopped rather than gone quiet. So the white noise is for about a fortnight, not a night — and it is better to say that at the start than to promise a quiet house tomorrow.
