How baiting works
Bait stations are placed where termites are active, or around the property. Worker termites feed on the bait and carry it back to the colony, which declines over the following weeks. The operator returns to check and top up the stations until activity stops, and may keep stations in place for monitoring afterwards. More on baiting.
PestClinic describes two placements: in-ground stations around the property, and above-ground (AG) bait stations fixed directly onto active mud trails indoors. It says colony elimination with baiting typically takes 4 to 12 weeks, followed by monitoring every 6 months to a year (PestClinic, Termite Treatment).
How soil treatment (a chemical barrier) works
A liquid termiticide is applied to the soil around or under the building, or injected into walls and floors through drilled holes, to create a treated zone that termites contact as they travel. It's most common for landed homes and for new construction, where the soil can be treated before the slab is laid.
Side by side
| Baiting | Soil treatment (chemical barrier) | |
|---|---|---|
| Target | The colony, via termites carrying bait back | A treated zone between the soil and the building |
| Speed | Gradual, typically 4–12 weeks with repeat visits (PestClinic, Termite Treatment) | Creates a treated zone once applied |
| Disruption | Low: stations, no drilling in most cases | Can involve drilling and injecting, or trenching around the house |
| Typical fit | Flats, finished interiors, where drilling isn't practical | Landed homes, new builds and major renovations |
| Published price | From S$700 per year with monitoring (Rentokil Singapore, Termite Treatment Price in Singapore) | From S$900 pre-construction, from S$1,600 for existing buildings (Rentokil Singapore, Termite Treatment Price in Singapore) |
Which should you choose?
- HDB flats and condos: drilling into slabs or common property often isn't practical, so baiting or spot treatment is common. Check with your Town Council or MCST if common areas are involved.
- Landed homes: operators may suggest soil treatment, baiting or a combination, depending on where the termites are coming from.
- Drywood termites: neither is usually the main answer. They live inside the wood, so local treatment such as foam is more common.
Some operators combine methods, for example baiting an active colony and then treating the soil. Rentokil lists post-construction options as spot treatment, a chemical barrier around the perimeter, or a combination (Rentokil Singapore, Termite Treatment Price in Singapore). Ask why they recommend what they do.
Do you need to move out?
For most baiting and soil treatments, no. PestClinic notes that vacating isn't required for most baiting or soil treatments, though fumigation, which is used for severe drywood cases, may require it (PestClinic, Termite Treatment). Your operator will tell you if any rooms need to be cleared.
Not sure which kind of termite you have? Read subterranean vs drywood termites first, because baiting doesn't work on drywood termites.
Questions to ask
- Which species is it, and how did you confirm it?
- Why this method for my home?
- How many visits, and how will you confirm the colony is gone?
- What does the warranty cover, and for how long?

Questions
Is baiting slower than soil treatment?
Usually, yes. Baiting relies on termites feeding and sharing the bait, so it works over weeks with repeat visits. Liquid treatment creates a treated zone once applied, but doesn't target the colony in the same way.
Can I use both baiting and soil treatment?
Yes. Some operators combine the two, for example baiting an active colony and then treating the soil to protect the building.
Which is better for an HDB flat?
In flats, drilling and soil treatment are often not practical, so baiting or spot treatment is common. A licensed operator should confirm this after inspecting.
