You wipe the trail, they are back in an hour, in the same line. There are four reasons for that, and three of them you can fix.
Four reasons: the chemical trail was not fully removed, the food source is still there, the entry point is still open, or the colony is large enough to keep probing.
The first three you can address yourself. The fourth is what treatment is for — £190 for a flat, £220 for a house.
An ant trail is a chemical path laid down by workers. Other ants follow it by scent, not by sight.
Wiping the visible stretch across a worktop removes the ants and a portion of the trail — but the rest of the route, up the wall, along the skirting, into the cupboard and out through the gap, is untouched. The next ant picks it up where you stopped cleaning.
Even a perfectly cleaned trail gets relaid if the destination is still worth walking to.

Sealing the entry point is what converts a recurring problem into a resolved one. In a house that is usually a patio junction, a door threshold, a crack in mortar or a pipe entry. In a flat it may be a gap around pipework, a perished window seal, or — awkwardly — a communal riser you cannot touch.
Read nextHow Do You Get Rid of Ants From Kitchen Cupboards in Wealdstone? →If you have done the first three properly and they are still coming a fortnight later, this is the answer.
A large established colony close to the building sends out scouts continuously. It does not need a trail to persist; it will find your kitchen again. That is the situation treatment is for, because treatment addresses the colony rather than the trail.
Heavy rain floods shallow nests and pushes activity toward drier sheltered ground — often against a building and then inside it. A trail that only appears after heavy rain usually settles once the ground dries, and is less likely to need treatment.
Ant activity rises sharply in warm weather. A trail that appeared during a hot fortnight and vanished afterwards was weather, not an infestation.
For a few days in mid-summer, colonies release winged reproductives all at once, across the whole area on the same day or two. Startling, brief, and not a reason to treat.
Before booking anything, do this properly once:
If they return within days, you have reason four and treatment is warranted. If they do not, you have saved £190 and we would rather that.
You can — bait stations placed directly on the trail have a sensible mechanism. Do not spray at the same time; spraying kills the workers that would carry bait to the colony.
A colony near the building and an open route. Sealing the route is what breaks the annual cycle.
Usually yes, probing different routes. Tell us all of them when you enquire.
Something else that recurs each summer — wasp nests. That one is a £90 fixed cost in Wealdstone, guaranteed.
Four reasons: the chemical trail was not fully removed, the food source remains, the entry is still open, or the colony is large enough to keep probing.
The whole route — up the wall, along the skirting, into the cupboard — with hot soapy water or dilute vinegar, once and thoroughly.
The sticky ring under jars and bottles in a cupboard.
Heavy rain floods shallow nests and pushes activity toward drier sheltered ground, often against the building.
Often not. Ant activity rises sharply in warm weather and settles again.
Bait stations placed directly on the trail can work on a modest problem. Do not spray at the same time.
A colony near the building and an open route. Sealing the route breaks the cycle.
If they return within days after you have cleaned the whole route, removed the food and sealed the entry.
Do the two-week test first. If they come straight back, that is a colony and treatment is warranted.
