7 Best Rat Control Services in Singapore (October 2026)

NEA names three rodents, and they live in different places. The Norway rat is heavy, with a blunt nose and a short tail. It digs, so you'll find it at ground level and below: drains, burrows by bin points, the back lanes behind food shops. The roof rat is slimmer, with big ears and a tail longer than its body, and it climbs. That's the one running across the false ceiling of a terrace house at night. The house mouse is the smallest and likes warm, dry corners such as kitchen cabinets, store rooms and F&B back-of-house.

Look for dark droppings near food or along walls (fresh ones are soft and shiny), gnaw marks on cables and plastic, and greasy rub marks low on walls and pipes where rats run the same route every night. Outside, NEA describes burrows as round holes 2 to 4 inches wide with loose soil around them. Inside, the giveaway is noise in the ceiling after dark.

Poison alone keeps failing, for a few reasons. Rats are suspicious of anything new, so fresh bait can sit untouched for days, and Anticimex notes that some become resistant to certain poisons. The ones that do eat it often die where they nest, which in a landed house means inside the ceiling. And the gap they came through is still open. Rentokil points out that rodents can squeeze through a 1cm gap.

What works takes longer. Inspect to find the entry points, the nest and the food. Seal gaps around pipes, doors and ceiling edges. Put bait in lockable stations outdoors and along runs, use traps indoors so the bodies are recovered, and keep coming back until there's no fresh activity. Every company on this list describes some version of that on its own site.

Most rodent companies won't publish a price, because it depends on how the rats get in and how much sealing is needed. These are typical ranges from the published prices and quotes I found. Use them to compare quotes, not as a promise.

If you're looking to hire a rat exterminator in Singapore, this is how I'd narrow it down.

1. NEA registration, checked yourself. NEA says only companies registered with it as vector control operators can be engaged for vector control work, and their staff must be licensed technicians or certified workers. NEA publishes the register on that page, and all seven companies here are on the September 2026 list.
2. An inspection before a price. A company that quotes a rat job over the phone without seeing the place is guessing. I want someone who looks for entry points, nests and food first.
3. Proofing in the scope. NEA rat guidance tells owners to repair the structural defects rats shelter in, and its advice for homes includes sealing gaps in false ceilings. If the quote doesn't mention sealing, ask why. Bigger gaps may need a builder, and my renovation contractors guide or the handyman services hub is where I'd look.
4. Lockable bait stations and traps indoors. Bait should sit in tamper-resistant stations, outside or along runs. Inside the house, especially above a ceiling, I'd rather see traps, so nothing dies where you can't reach it.
5. Follow-up visits and a written report. One visit rarely ends a rat problem. I look for a set number of return checks and a report after each one.
6. Reviews at volume. I trust a 4.8 across hundreds of reviews more than a 5.0 across ten.

I started from NEA's register of vector control operators dated 30 September 2026, picked companies with a dedicated rodent service, and read each rodent page for methods, proofing and follow-up. Pages that said little beyond "we treat rats" didn't make it. I checked Google ratings on Google Maps on 27 October 2026 and only quote the ones I saw.

I also gave weight to anything that helps you compare, like a published price or a monitoring system, and counted Rentokil and Killem once. Ratings change and companies get bought, so check the latest before you book.

Town councils handle rat control in the communal areas of HDB estates, and NEA funds them for it under its Rat Attack Programme, according to a 2020 parliamentary reply from the Ministry of Sustainability and the Environment. Inside your own flat, keeping rats out and hiring any pest control company is your job.

Report rats at a bin centre, drain or void deck to NEA through the OneService app. Don't pay a private company for communal areas. In a condo, go to the managing agent first. On landed property, the house, roof and garden are all yours.

S$450 is the clearest published figure: Protect Pest Control charges that for a one-off rodent treatment in an HDB flat, condo, terrace or semi-D, S$500 for a bungalow, and S$1,350 for a year of monthly visits. Most other rat control companies in Singapore quote after a free inspection, because the sealing work varies so much.

Compare the scope, not just the total: how many visits, whether proofing is included, and whether there's a free return visit if activity comes back.

NEA describes the roof rat as an agile climber that reaches roofs and false ceilings, which makes it the usual source of noise overhead. Rats are most active after dark, so scratching and scurrying in the ceiling at night is the classic sign. Check for droppings, gnawed cables and rub marks near ceiling edges.

Don't throw poison into the ceiling yourself. A rat that dies up there smells for days, and the panel has to come off to get it out. Ask for an inspection of the ceiling void and for traps up there instead.

Two things sink a poison-only rat job. First, rats are wary of new things and can ignore fresh bait for days, and the ones that eat it often die inside walls or ceilings. Second, the gap they came through stays open, so new rats move in. Poison works as one part of a plan.

The plan that holds up is inspection, sealing, lockable bait stations outdoors, traps indoors and follow-up visits. If you also see cockroaches around the bin chute or kitchen, it's usually the same food source, and my cockroach control guide covers that side.

Up to S$20,000, up to three months' jail, or both, for a first offence under the Control of Vectors and Pesticides Act, according to a 2023 written reply from the Ministry of Sustainability and the Environment. NEA can use it against owners whose premises let rats breed or shelter, poor refuse management included.

The same reply puts the fine for poor refuse management at up to S$1,000, plus up to S$100 a day if the offence continues after conviction. The ministry also told Parliament in February 2025 that NEA would tighten enforcement on rat-related lapses from 1 April 2025, Food shops carry a second risk: the ministry's 2020 reply says operators must hold a pest control contract, and serious or repeated offences can get the licence suspended or cancelled.
