Ants are a common issue in Singapore homes, especially in HDB flats and condominiums. When they return again and again, most homeowners compare two choices: a one-time ant treatment or a bi-monthly pest control plan. This guide explains which option gives you better value, using the actual pricing from Termite Specialist Pte Ltd.

What One-Time and Bi-Monthly Treatments Mean
One-Time Ant Treatment
A single visit that includes an inspection, targeted gel baiting, and surface treatment.
It works best for light or first-time infestations.
You can learn more about our methods on the ant pest control in Singapore page.
Bi-Monthly Pest Control Plan
Six scheduled visits over one year.
Includes inspections, treatment, follow-up checks, and monitoring.
Suitable for recurring or moderate infestations.
Both services follow NEA guidelines and are performed by trained technicians.

These prices are used in the cost comparison below.
Cost Comparison: When Each Option Makes Sense
One-Time Treatment
Lower upfront cost
Ideal for minor issues or when ants appear only once in a while
Using an HDB flat as the example:
- One visit = $140
- Two visits a year = $280
- Three visits = $420
- Four visits = $560 (same as condo bi-monthly plan)
If ants return three or more times a year, one-time visits become more expensive than a plan.
You can also check the national price range on our ant pest control cost Singapore guide.
Bi-Monthly Treatment
A scheduled plan that averages:
- $86.67 per visit for HDB (520 ÷ 6)
- $93.33 per visit for condos (560 ÷ 6)
You get scheduled monitoring, follow-up checks, and preventive treatment.
This reduces the chances of ants returning and avoids emergency call-outs.
Which Option Is More Cost-Effective?
Choose One-Time Treatment If:
- You saw ants only once or twice
- The issue is limited to a small area
- You want a lower upfront cost
Choose Bi-Monthly Treatment If:
- Ants return every few months
- Several rooms are affected
- You live in a condo with shared ducts or walls
- You want continuous monitoring and prevention
For homes with repeated ant activity, the bi-monthly plan usually gives better long-term value.
HDB Example: Real Scenario
Sugar ants commonly appear in HDB kitchens.
If they return after a one-time treatment, you will pay another $140.
If this happens two or three times a year, the cost becomes higher than the bi-monthly plan.
This makes the $520 bi-monthly plan more cost-effective after the second call-out.
For HDB owners comparing other pests, see our residential pest control in Singapore page.
Condo Example: Why Plans Often Work Better
Condo units share ducts, refuse chutes, and exterior walls.
Even if your unit is treated, ants may re-enter from neighbouring homes that are not treated.
A bi-monthly plan allows regular treatment of hotspots, keeping ant trails under control and preventing colonies from building up.
To see how ants and other pests behave differently, you may also refer to termite vs ant.

- Inspection of kitchens, bathrooms, balconies, and service areas

FAQ
Is the bi-monthly plan safe for children and pets?
Yes. All products used are NEA-approved.
How long do ants take to disappear after treatment?
Most trails fade within days. Full control of the colony can take one to two weeks.
Do I need to be at home during treatment?
Yes, an adult must be present to allow access to key areas.
Final Recommendation
If you rarely see ants, a one-time treatment is good enough.
If ants keep coming back or you live in a condo with shared ducts, a bi-monthly plan is more cost-effective and provides better protection.
