Short answer: Cut off food and water, seal the gaps they come in through, clear clutter, and put gel bait where you have seen activity.
Spraying the ones you see does nothing about the nest. If cockroaches keep appearing after two to three weeks of this, show up in daylight, or turn up in more than one room, the infestation is established and needs professional treatment to reach where they are breeding.
Why Are Cockroaches So Common In Singapore Homes?
Heat, humidity, and a steady supply of food, water and hiding places. They come in through gaps around pipes, drains, doors and other openings, then settle where it is dark, damp and close to food:
- Kitchens and food prep areas
- Under sinks and inside cabinets
- Behind fridges and other appliances
- Bathrooms and utility areas
- Around floor drains and pipes
- Rubbish bins and disposal areas
- Storerooms and cluttered corners
How Do I Get Rid Of Cockroaches At Home?
Five steps, in this order. Each one removes something cockroaches need.
1. Remove Food Sources
Keep food in sealed containers. Never leave uncovered meals or snacks out overnight. Wipe crumbs and spills as they happen, and check under appliances and furniture where they collect. Pick up pet food bowls rather than leaving them out.
2. Keep The Kitchen Dry
Cockroaches need water as much as food. Check under the sink and around plumbing for leaks, wipe wet surfaces, and don’t leave water standing in the sink overnight. Persistent damp usually means a plumbing fix is part of the cure.
3. Take Out The Rubbish Regularly
Use bins with tight lids and empty them often, especially when they hold food waste.
Wash the inside of the bin now and then to remove residue and smell, and keep the floor around it clean. Scraps outside the bin attract pests, as well as scraps inside it.
4. Seal Gaps And Entry Points
Cockroaches fit through very small gaps. Check around:
- Pipes and plumbing fixtures
- Doors and windows
- Floor and wall gaps
- Kitchen cabinets
- Drainage areas
- Cracks around appliances
Weatherstripping or sealant handles small gaps; larger openings need proper repair.
5. Reduce Clutter
Stacked cardboard, newspapers and unused containers are cockroach shelters.
Keep storage organised and cardboard off the floor, especially in kitchens, storerooms and utility areas.
Do Cockroach Baits And Traps Work?
Baits work because cockroaches carry the poison back to the nest. Traps mostly tell you where the cockroaches are.
What it does | Best use | |
|---|---|---|
Sticky traps | Catch individuals; show where activity is concentrated | Monitoring, finding hotspots |
Gel bait | Attracts cockroaches, who feed and spread it to others | Reducing an active population |
Contact spray | Kills the one you see | Nothing beyond that one |
Place bait where you have seen activity, follow the product instructions, and keep it away from children and pets.
Don’t put bait next to strong cleaning products or insecticide sprays; the smell puts cockroaches off and the bait stops working.
Should I Spray Cockroaches When I See Them?
Spray if you like, but it won’t fix the problem. It kills one insect. The rest are in cracks, cabinets and appliances you can’t reach.
If the population is established, spraying gives temporary relief at best. Sanitation, sealing, monitoring and, where needed, professional treatment together do what spray alone cannot.
What Are The Signs Of A Cockroach Infestation?
One cockroach can wander in by accident. These signs mean they are living with you:
- Regular sightings
- Cockroaches out in the daytime (they hide by day unless the nest is crowded)
- Small cockroaches or nymphs, which mean breeding nearby
- Droppings
- Egg cases
- A persistent musty smell
- Cockroaches in more than one room
Why Do I Keep Seeing Cockroaches After Cleaning?
Because cleaning removes their food, not their nest. An established population hides in wall gaps, cabinets, appliances and pipe openings that cleaning never reaches.
In apartments and condos, they may also be coming from a neighbouring unit or shared building areas. If they keep appearing after regular cleaning and the five steps above, find where they are coming from, and consider professional treatment.
When Should I Call Pest Control?
When any of these apply:
- Cockroaches keep appearing despite your own efforts
- They show up in several rooms
- You see them regularly in daylight
- You have found nymphs or egg cases
- They seem to come from areas you can’t reach
- They return soon after a treatment
A technician assesses the property, finds the activity zones, and recommends treatment based on the species and scale of the infestation.

In apartments, report recurring problems to building management; the source may be shared.
FAQ
What Is The Fastest Way To Get Rid Of Cockroaches At Home?
Remove food and water, then put gel bait where you’ve seen activity. If they keep appearing, professional treatment is faster than more DIY.
Why Do I Have Cockroaches Even Though My House Is Clean?
They come in through gaps, drains and pipes, or from neighbouring units. A clean house has less food for them, but it doesn’t stop them entering or hiding.
Does Killing One Cockroach Mean There Are More?
Not always. Repeated sightings, and especially small cockroaches, do mean there is a population nearby.
How Can I Stop Cockroaches From Coming Back?
Seal food, take out rubbish, remove moisture, reduce clutter and seal entry points. If they still return, get professional treatment.
Final Thoughts
Getting rid of cockroaches means removing what attracts them, not just killing what you see. Cut off food and water, take away hiding places, block entry points, and monitor to see whether it’s working.
Repeated sightings or signs of breeding mean the nest is somewhere you can’t reach, and in Singapore’s climate an infestation left alone only gets bigger.
Get it treated early by calling a professional pest control specialist. The sooner you act, the easier and more cost-effective it is to eliminate the problem before it spreads beyond control.
