To get rid of ants in a Singapore kitchen or home, do not just spray the trail, which leaves the nest. Baiting lets ants carry the treatment back to the colony. Four Solutions (NEA licensed) treats ants at the harbourage, not just the foragers you see.
A trail of ants across the kitchen counter or into a cabinet is one of the most common household pest problems in Singapore. Wiping the trail and spraying the ones you see feels like progress, but they are back the next day on a slightly different route. Here is why, and how to actually get rid of them.
Why ants keep coming back
The ants you see are foragers from a much larger colony nesting out of sight, often in a wall, under flooring, behind skirting or outside near the unit. They follow scent trails to food and water, so wiping one trail just sends them along another. Spraying the foragers does not touch the nest or the queen, which keeps producing more. That is why the trail returns.
How to get rid of ants properly
- Do not just spray the trail. Killing foragers leaves the colony intact. Baiting lets ants carry the treatment back to the nest.
- Find the entry points and the direction of travel, which point toward the nest.
- Remove food and water access. Store food sealed, clear crumbs and spills, and fix damp spots.
- Treat the harbourage. Reaching the nest is what actually clears the colony.
Why DIY often fails
Supermarket sprays are designed to kill on contact, which removes the visible ants but signals the colony to keep sending more and can even cause some species to split and spread. Baiting and treating the harbourage work with how the colony behaves, which is why they give a lasting result where spraying does not.
When to call a professional
It is worth getting help when ant trails keep returning, appear in several rooms, get into food or appliances, or you cannot find the nest. Four Solutions treats ants alongside cockroaches and flies using baiting, source reduction and targeted treatment matched to the situation, for homes and businesses across Singapore.

Ant control FAQs
Why do ants keep coming back after I spray?
The ants you see are foragers from a hidden colony. Spraying kills them but not the nest or queen, so the colony keeps sending more along a new trail. Baiting and treating the harbourage are what clear the colony, not surface spray.
How do I get rid of ants in my kitchen?
Remove food and water access, follow the trail to the entry point, and use baiting so ants carry the treatment back to the nest. Where the colony is established or hard to reach, professional treatment of the harbourage gives a lasting result.
Where do the ants come from?
They nest out of sight, often in a wall, under flooring, behind skirting or just outside, then send foragers in along scent trails to food and water. Finding the direction of travel helps locate the nest.
Is spraying ants a bad idea?
Contact spray removes the visible ants but can prompt the colony to keep sending more, and some species split and spread when sprayed. Baiting works with how the colony behaves, which is why it lasts.
