The estate was landscaped as it was rebuilt, so the ground around the houses and low-rise flats is mostly block paving, kerbed path edges, mown grass and planted beds laid up against brick and render. Black garden ants nest in the bedding sand and soil under all of it, then take the shortest route indoors.
Where a trail keeps returning to the same corner of the kitchen, book ant control: £190 for a flat and £220 for a house. Call 0800 955 2347.

Garden ants want ground that is loose, well drained and warmed by the sun, and the sand bed under block paving describes that almost exactly. Look along the edge restraint of a path or a parking bay, at joints where the blocks have lost their sand, and at the strip where paving finishes against the wall of the building. Fine granular soil pushed up in little heaps is the colony underneath telling you where it is. Finding an ant nest covers how to read those heaps, and where ants nest around houses has the wider list.
Beds of shrubs and bark mulch run right up to the walls in places, and a bed on a sunny elevation stays warm and dry a little way down. A colony sitting in one is inches from the building, so its workers have next to no distance to cover before they reach a door or an air brick. Where the planting is communal it is maintained under contract, so lifting blocks or digging into a bed is not a resident's job; note where the ants surface and pass that on when you report it.

Newer homes are built with low weathered thresholds at patio and back doors so that there is no step to trip over, and the trade-off is a shallow detail with a drainage channel and a track that ants walk along without any trouble. In a ground-floor flat whose doors open onto a courtyard, the kitchen may be only a few strides from the planting outside. Follow the trail to the point where it leaves the room, then look at the same spot from outside; the two ends nearly always line up. Why ants keep coming into the kitchen explains what draws them that far.
Garden ants thin out sharply with height, so a flat on the first or second floor of a low-rise block sees far fewer of them than the one below it. If ants on an upper floor are tiny and pale rather than black, say so when you ring, because that is a different insect altogether and shop-bought spray makes it worse instead of better — Pharaoh ants vs garden ants explains why. Small brown insects that scatter from behind the kickboard when the light goes on are cockroaches rather than ants of any sort.
On a handful of close, humid afternoons in July and August every colony in the area sends up winged queens and males together, and over paving and mown grass the effect is hard to miss. They will not start a nest indoors and the flight is over within hours, so on its own it is not a reason to book anything. What it does tell you is precisely which crack, kerb joint or bed the colony has been living under all year, which is worth remembering. Why flying ants appear indoors covers the day itself; winged insects working one opening steadily for weeks are a wasp nest and not ants at all.
Ants do not vanish the moment a visit ends, and how long they take depends on the species and where the colony sits; how long ant treatment takes runs through what affects it. If the trail is as strong as ever a while later, ring back and describe where it now runs. When an ant problem needs treatment helps if you are still weighing it up.

Once the colony has been dealt with, the aim is to make that last few feet not worth walking. How to stop ants entering your home goes further, Ant Control Brent covers the rest of the borough, and ground-floor flats around Wembley deal with much the same layout.
Ant control in Stonebridge is £190 for a flat and £220 for a house. A house on the estate is priced as a house, while a flat in a low-rise block is priced as a flat whichever floor it is on, and holding your home on shared ownership changes neither figure. The price is for dealing with the ant problem at your own home, and we talk through what the visit involves before anything is booked.
| Treatment | Price |
|---|---|
| Ant Control – Flat | £190 |
| Ant Control – House | £220 |
The drainage detail under that sort of threshold has to stay clear, so packing it solid is not the answer. Keeping the channel clean and dealing with the colony outside is what stops the trail, and a brush seal fitted by whoever maintains the door helps too. Book ant control if the trail keeps coming back.
Better not. Planting and paving in shared areas are looked after under contract, and powder scattered on a bed washes away with the first rain. Note which bed or joint they come up through, report it, and book treatment for your own home.
Usually not. Black garden ants live outdoors and come in only to forage, which is why the trail always leads back to a door, a pipe or an air brick. Winged ants coming up through a kitchen floor are the exception worth mentioning, as that suggests a nest right under the building.
Garden ants are much less common that high up. Look carefully at the size and the colour, because very small pale ants in a warm building are a different species that lives indoors and should not be sprayed. Tell us what you are seeing and we will go through it with you.
A surface product mostly reaches the foragers, while the colony under the paving carries on producing fresh workers that pick up the same scent trail. Why ants come back after DIY treatment goes into it.
Garden ants are a nuisance rather than a structural problem, and they do not eat timber. A trail that keeps returning is still worth dealing with, because it means a well-established colony sitting hard against the building.
It often explains yours. A single colony under a shared path or a run of block paving can supply trails into several homes at once, so it is useful to know when you call.





















Tell us whether it is a house or a flat, which floor, where the trail comes in, what the ants look like and your NW10 postcode. Prices for the rest of the borough are on Ant Control Brent.
