Mice Control — Cambourne

Where Should You Look for Mouse Entry Points Around a Cambourne Property?

If a mouse is in your kitchen, the way in is very often in the kitchen too — and behind something you have never moved.

A kitchen concentrates everything a mouse needs and everything a building does badly: food, warmth, and more holes through the external wall than any other room in the house.

Why Kitchens Have So Many Openings

Count them. Hot and cold supply, waste, gas, electrical, an extractor duct, a boiler flue, condensate, an outside tap, sometimes a soil pipe. Every one of those is a hole through the wall, and every one was filled by somebody working quickly.

BPCA put a mouse at a gap of 5mm, roughly the diameter of the eraser end of a pencil. The clearance left around a pipe after the filler has shrunk is very often more than that.

The Places to Look, In Order

  1. Under the sink. Waste and supply pipes through the wall or floor, usually behind a cupboard nobody empties. The single most productive spot in most kitchens.
  2. Behind the kickboards. Unclip one — it takes thirty seconds. The void behind runs the length of the unit run and connects to the wall, the floor and every service penetration on that side.
  3. Behind the washing machine and dishwasher. Supply, waste and a power point, all through the wall.
  4. Behind and under the cooker, and around a gas supply.
  5. Around the boiler, including the flue penetration and the condensate run.
  6. At the extractor duct where it passes through the wall, and check the external grille while you are outside.
  7. Where a modern extension meets the original wall, which is where shrinkage cracks appear.
  8. Under the back door, at a worn threshold.
The kickboard void is the one that matters most. It is continuous, it is dark, it is warm, it connects to the outside wall at several points and almost nobody ever looks in it. If there are droppings anywhere in a kitchen, that is the next place to look — and it is where treatment usually goes.

What You Are Looking For

  • Daylight, which is the easiest test of all where a wall backs on to outside
  • A draught, felt on the back of a hand on a cold day
  • Smearing at the edge of an opening, which is close to proof
  • Droppings concentrated near one spot
  • Gnawing at the edge of a plastic pipe collar or a timber batten
  • Filler that has shrunk, cracked or fallen out

Then Check the Same Points Outside

Every one of those penetrations exists on both sides of the wall, and the external side is usually easier to see and easier to seal. Walk the outside of the kitchen wall with a torch held low and look at every pipe, cable, duct and vent.

Note what you find, and do not seal it yet — proofing comes after the property is confirmed clear, or you seal the animals inside.

Common Questions

Where do mice get into a kitchen?
Most often around the pipes under the sink, behind the kickboards, and behind the washing machine, dishwasher, cooker or boiler — anywhere a service passes through the wall.
What is behind a kitchen kickboard?
A continuous void running the length of the unit run, connecting to the wall, the floor void and every service penetration on that side. It is the most useful place to look.
How do I check for a gap?
Torch held low and raking across the surface, look for daylight, feel for a draught on a cold day, and look for smearing at the edge of any opening.
Should I seal what I find?
Note it, but not yet. Proofing comes after the property is confirmed clear, or you seal the mice inside.
