Break the trail, remove what it leads to, find where it comes in. Most flat ant problems end there, without anyone spending anything.
Wipe the trail with detergent, remove the food source, then find the entry point. Most kitchen trails end within a week.
Do not spray it. Spraying kills foragers, scatters the rest, leaves the queen producing replacements, and with pharaoh ants actively makes it worse.
Ants follow a chemical path laid by a scout. Washing it away removes the road itself, which is why detergent outperforms almost everything sold for the job.
£190 for a flat, £220 for a house — and honest advice about when you need neither.
View Ant Control Rayners Lane →| Remedy | Verdict |
|---|---|
| Insecticide spray on the trail | Counterproductive. Queen unaffected, foragers scattered |
| Chalk or talc lines | Briefly deters, no effect on the colony |
| Cinnamon, coffee grounds, peppermint | Mild repellent at best |
| Ultrasonic repellers | No credible evidence |
| Boiling water | Not usable indoors, and rarely reaches the queen |
| Sealing everything up | They find another route |
Garden ants become inactive in cold weather. Pharaoh ants do not — they live in the warm.
Helpful, not essential. Bait carried back finds it for you.
Black garden ants are essentially harmless. Pharaoh ants in a building are a different matter.
A wasp nest is not something to tackle yourself — £90 fixed in Rayners Lane, guaranteed for 30 days.
Wipe the whole trail with hot soapy water going beyond both ends, remove the food source, and find the entry point. Most kitchen trails end within a week.
No. It kills the foragers, scatters the rest, leaves the queen producing replacements, and with pharaoh ants makes it actively worse.
Usually inside the building — along boxed pipework, a service run, or through a floor void from the flat below. Or they are pharaoh ants, which nest indoors.
Very small at about 2mm, yellowish or pale brown, trailing along warm pipework, and present in winter when garden ants are inactive.
They have multiple nests and queens inside the building, and spraying causes the colony to bud and split. They need a specific bait programme.
Mild repellents at best. They do not affect the colony.
Everyone has to seal food and clear crumbs, not one person. Partial effort achieves very little.
A persistent internal trail is worth reporting in writing. Pharaoh ants are a building matter rather than a housekeeping one.
Try detergent and sealed food for a week first. If they are small and pale, tell us straight away.
