Ants reaching the food store rather than crossing the worktop is the point at which this stops being a nuisance and starts being worth treating.
Empty the cupboard, discard what is contaminated, break the trail, and seal everything else.
Do not put anything down inside a food cupboard. No spray, no powder, no loose bait — and professional gel goes into cracks and hinges, never onto shelves.
People clear one cupboard and stop. The ants simply move to the next one, and it reads as the treatment failing.
£190 for a flat, £220 for a house — and honest advice about when you need neither.
View Ant Control Rayners Lane →| Never | Why |
|---|---|
| Insecticide spray on shelves | Contaminates food surfaces |
| Loose ant powder | Displaced easily, unsafe with pets and children |
| Bait laid on a shelf | Wrong placement, and reachable |
| A fogger | Contaminates the whole kitchen and does not reach the nest |
| Bleach in a confined cupboard | Fumes, and no effect on the colony |
| Professional gel in cracks and hinges | The correct approach |
Pharaoh ants in a food cupboard are a different matter entirely. They are about 2mm, yellowish-brown, active year-round, and they nest inside the building. Spraying makes the colony split. If the ants in your cupboard are pale rather than black, tell us before anything is applied — the whole approach changes, and in a block it is usually a building-level problem.
Anything opened and reached is best discarded. Sealed jars and tins are fine once washed.
Check every one. Empty the affected ones.
Activity usually falls within days and the colony clears over two to three weeks.
Something larger in the roof? Wasp nests are £90 fixed in Rayners Lane, guaranteed for 30 days.
Empty it completely, discard anything opened that ants have reached, wash it out with hot soapy water, break the whole trail, and seal everything in proper containers.
No. Never spray, powder or lay loose bait inside a cupboard you store food in. Professional gel goes into cracks and hinges, never onto shelves.
Yes, every one. People clear one cupboard and the ants simply move to the next, which reads as the treatment failing.
Anything opened and reached is best discarded. Sealed jars and tins are fine once the outsides are washed.
Because the food source in the cupboard is permanent. Removing it is what lets the cleaning work.
Usually around a pipe entering under the sink, through a unit's back panel, up from the plinth void, or along the wall behind the units.
They may be pharaoh ants, which nest inside the building and split when sprayed. Tell us before anything is applied — the approach changes completely.
When the trail returns within a day of every cleaning, ants are in more than one cupboard, or they are small and pale rather than black.
Empty it, wash it, seal everything. If they are pale rather than black, tell us first.
