Every Singapore home has had them: the housemates who never signed the tenancy agreement, never chip in for utilities, and have strong opinions about where you keep the sugar. One day the kitchen counter is spotless; the next, a single scout ant is marching across it with the confidence of someone who has already told all their friends.
And it is never just ants. There is the cockroach that materialises at eleven at night, precisely when you are least emotionally prepared. There are the mosquitoes that treat your ankles as a buffet the moment you sit on the balcony. Living in the tropics has many perks — this rotating cast of uninvited guests is not one of them.
Think about what a pest is looking for: warmth, moisture, food and shelter. Now think about what Singapore offers: 30-degree days, humidity that never clocks off, and kitchens that produce something delicious most evenings. To an ant, your HDB flat or condo is not a home — it is a resort with an excellent breakfast spread.
High-rise living does not exempt anyone, either. Pests are excellent commuters. They travel through service pipes, along corridors and up rubbish chutes, and a tenth-storey unit is no more remote to a determined cockroach than a ground-floor one. If the whole block is their neighbourhood, the goal is simply to be the least interesting flat in it.

Ants are the organised ones. That lone explorer on your counter is a scout, and it is filing a report. Leave a splash of kopi or a few biscuit crumbs out overnight and the report reads: promising site, recommend full deployment.
Cockroaches are the night shift. They love warmth and damp, which makes the back of the fridge, the gap under the sink and the kitchen drain their favourite addresses. They are shy about daylight — which is why spotting one at noon is a sign the household has grown larger than anyone agreed to.
Mosquitoes are the freeloaders with the worst manners. They need surprisingly little to get started: a forgotten saucer under a plant pot, a vase topped up too long ago, a bit of water pooled on the balcony after a downpour. In Singapore, keeping still water out of the house is more than comfort — it is the habit the NEA reminds us about every dengue season, and it starts at home.
The good news: you do not need to turn your home into a fortress. You just need to be a consistently disappointing host. A few small habits do most of the work:

Sometimes, though, the housemates dig in. A trail that keeps reappearing no matter how often you wipe it away, cockroaches strolling about in daylight, or that telltale musty smell from a cupboard are all signs the problem has moved beyond what a supermarket spray can reach. Sprays deal with the individuals you can see; they rarely do much about the nest you cannot.
That is the point where it is worth handing things over to people who do this for a living. Pest Control is now one of the services you can book directly with Nimbus Homes, alongside old favourites like Deep Cleaning — which clears out the grease, crumbs and hidden build-up that attracted your uninvited guests in the first place — and regular Housekeeping to keep the welcome mat firmly rolled up. If your home has housemates you never agreed to, you can book a session at book.nimbushomes.com and let someone else serve the eviction notice.
