Why Kilburn's Rats Come From Below
Kilburn was built up in the Victorian and Edwardian decades, and so was the drainage under it. Where a clay pipe has cracked or a redundant connection was left open when a house was divided, rats living in the sewer reach the ground beneath the building, and the void under a suspended timber floor takes them where they like. That is why noise under a floor with nothing visible outside so often ends with a drainage contractor rather than a hole in a wall.
Lower-ground and basement flats
A flat at the bottom of a tall house is the first home a rat meets. Its floor sits at or below the drain runs, its rooms open onto a lightwell or a sunken area, and the airbricks and waste pipes serving it are all at ground level or lower. If you rent, tell the landlord or agent early: what turns up in the lowest flat concerns the whole building. How rats reach flats covers the routes.
Bins and food waste behind the High Road
Shops, cafés, pubs and takeaways along the High Road put trade waste out into yards, side alleys and shared bin areas, and a rat feeding there does not stay on the ground. Waste pipes, cable runs and gaps in tired brickwork lead up the back wall towards the flats above, so droppings behind the kitchen units of a flat over a parade are worth acting on. The premises themselves are business addresses, quoted per site.
The long gardens behind
Behind the houses are long gardens, some shared between the flats in one building and tidied by nobody in particular. Overgrown corners, timber left over from a conversion, bagged rubbish and open compost offer food and cover within one run of the back door. A rat nesting there works along the rear wall for a way in: the foot of a basement door, a cracked airbrick, the hole where a waste pipe leaves the brickwork. How rats get in has the rest.
Signs Worth Checking in a Converted House
- Dark, tapered droppings in an under-stairs cupboard, a meter cupboard or a basement store
- Smear marks along a soil pipe or around a hole where pipework passes through a wall
- Noise beneath the floor of a lower-ground room after dark, rather than inside the walls
- Gnawed bags or spilled food in a shared bin area or the yard behind a parade
- Burrows or flattened runs in the garden, beside a wall or a compost heap
The first signs of rats describes what those look like close up. Droppings the size of a grain of rice mean something smaller, and mouse control in Kilburn is the booking instead.
What to Do This Week
- Put rubbish inside a closed container, never in a bag on the floor of a shared bin area
- Keep dry food and pet food in tins or thick tubs, especially in a room let on its own
- Report an overflowing or broken bin store to the landlord, agent or freeholder in writing
- Leave airbricks alone: stuffing one blocks the floor void's air and sends a rat elsewhere
- Keep poison out of a shared garden or yard, where a cat or a child can reach it

What to tell us
When you book rat control, say whether it is a flat or a whole house, which floor a flat is on, and whether there is a basement, a lightwell or a shared garden. Mention a shop or takeaway below or behind you, and where you have seen or heard activity. Business premises are quoted per site, so say if the address is a shop or restaurant rather than a home.
Getting ready
Clear the cupboard under the sink and any under-stairs or meter cupboard where droppings have shown up, and make sure the basement, the rear area and the garden can be reached.
Afterwards
You will be told what was found and what happens next. How long it takes depends on the building and on whether the rats are coming from the ground beneath it, which this guide to timescales explains. Get back in touch if fresh droppings appear after a quiet spell.
Keeping Rats Out of a Kilburn House
Where the way in is a drain, sealing indoors settles nothing: a drainage contractor surveys the pipe and either repairs it or fits a one-way blocker, and rats and drains explains that. Above ground it is simpler. Keep planting and clutter back from the rear wall, have a cracked airbrick replaced with one that still passes air, and close small gaps around pipes and under a basement door with rodent proofing in Kilburn. Rat proofing sets out what lasts.
For rats in the rest of the borough, see Rat Control Brent. The older terraces of neighbouring Kensal Green stand over much the same kind of drainage.
