The Kilburn homes that get ants are the ones closest to the soil: lower-ground and garden flats in big converted houses, where the kitchen sits level with a paved lightwell at the front or a shared path at the back. Black garden ants nest in the sand and rubble beneath that paving and walk in through whatever gap is nearest.
If the same trail keeps reappearing along a skirting board, book ant control: £190 for a flat, £220 for a house. Call 0800 955 2347.
Black garden ants want loose, warm, free-draining ground they can tunnel through undisturbed, and the made ground around an old house gives them that: bedding sand under worn flagstones, rubble behind a retaining wall, the strip of dry soil at the foot of a back addition. A lower-ground kitchen sits on the same level as all of it. The colony itself stays outdoors; what comes indoors is a foraging line after something sweet. Where ants nest around houses covers the other likely spots.

A lightwell is a small paved box that holds the afternoon sun, drains slowly and is hardly ever disturbed. Slabs work loose down there, the steps from the pavement crack, and the wall alongside carries air bricks and pipe entries at the height of a kitchen worktop. Small heaps of fine soil pushed up between the flags in June are the clearest sign that a colony is living underneath.

At the back, several flats may open onto one path, one flight of steps or a garden nobody owns alone. Ants use the joint where a back addition meets the main house, the threshold of a door that no longer shuts tightly, and the holes where waste pipes leave the kitchen wall. Trace the line indoors back to the point it enters the room, then look at the same spot from outside; why ants keep coming into the kitchen explains what they are after. Where the paving is communal, report loose slabs to the freeholder or managing agent rather than lifting them. A steady stream of insects using one gap at roof level for weeks is not ants but a wasp nest.
For a few humid days each summer, colonies send out winged queens and males together. Watching them rise from a crack in the lightwell or between the flags of the back path marks where a nest already was, and a day or two later it is finished. Winged ants coming up through a kitchen floor, from under a skirting or around an old hearth matter more, because the nest may be beneath the floor rather than the yard, so mention it when you book. Why flying ants suddenly appear indoors goes into what is happening.
Pharaoh ants are a different proposition from garden ants. They are minute, yellowish and almost translucent, they nest inside warm buildings rather than in the ground, and they are associated with heated blocks rather than gardens. Around Kilburn that points to the newer blocks and the estates rather than a converted house. A trail several floors up, nowhere near soil, is the clue.
A Pharaoh ant colony runs several queens at once, and wiping out the workers on a worktop can prompt the rest to divide and set up again elsewhere, turning one kitchen into three. Put shop-bought products away, leave the trail so it can still be followed, and read Pharaoh ants vs garden ants first. Because the nests sit in wall voids and warm pipe runs, neighbouring flats are often involved: ask whether anyone else has seen them, and tell your landlord, agent or whoever manages the block. Can ants nest inside walls? explains why the nests are so hard to pin down.
Ants can still be about for a while after the visit, and how long depends on the size of the colony and how far it runs under the paving; how long ant treatment takes explains what affects that. If activity has not fallen away, get back in touch and describe what you are still seeing. Small brown insects that scatter from under a kitchen unit when the light goes on are more likely cockroaches.

Once the colony is dealt with, a few small jobs at the outside wall make a repeat less likely. How to stop ants entering your home goes further, Ant Control Brent covers the rest of the borough, and neighbouring Kensal Green has the same kind of older terraces.
Ant control in Kilburn is £190 for a flat and £220 for a house. A converted flat, a bedsit or a flat in one of the South Kilburn blocks is priced as a flat, even where several front doors share one entrance, while a house still in single occupation is priced as a house. The price covers dealing with the ant problem at your address, and we go through what the visit involves before you confirm anything.
| Treatment | Price |
|---|---|
| Ant Control – Flat | £190 |
| Ant Control – House | £220 |
It puts the kitchen on the same level as the ground the colony is living in, so a foraging trail has only a short way to travel. Look along the bottom of the outside wall, at the air bricks and at the lightwell paving for where they come and go. Ant control for a flat is £190.
In most conversions the lightwell and its steps are part of the building rather than yours alone, so reporting loose paving beats digging it up. Watching where the ants disappear tells us as much anyway. How to find an ant nest shows what to watch for.
It helps a great deal to know. A single colony under a shared path can feed trails into two or three kitchens at once, so tell us if the neighbours are seeing them as well, and mention it to whoever manages the building.
It suggests a nest under the floor or in the ground beneath the back addition, not out in the yard. Vacuum them up, keep that room's door shut for the afternoon, and tell us about it when you book so we know where to start looking.
Probably not. Very small pale ants in a heated block are likely to be Pharaoh ants, which nest indoors and travel between flats. Do not spray them, and say how small they are when you call. Ant control in a flat is £190.
Tell your landlord or agent in writing where the ants come in and when they started, since the route in is usually part of the fabric of the building. Ant treatment is priced for the property, £190 for a flat and £220 for a house, whoever books it.
Products that kill the workers you can see rarely reach a colony sitting under the paving, and it simply sends out more. Why ants come back after DIY treatment covers that, and when an ant problem needs treatment helps you judge whether to book.





















Tell us whether it is a house, a converted flat or a flat in a block, where the ants get in, what size and colour they are, and your NW6 postcode. Ant prices across the borough are on Ant Control Brent.
