Four Solutions provides NEA licensed cockroach removal and treatment in Singapore (Reg. NEA201812722M), using gel baiting, residual treatment, drain treatment or chemical-free heat matched to the activity and eggs. We assess hiding places, entry points and conditions supporting the activity, then explain treatment scope and follow-up.
Cockroaches breed quickly and hide their eggs where sprays cannot reach. Ants and flies also return when food, moisture, drains or entry points are not handled. Effective cockroach removal in Singapore means treating the harbourage and eggs at the source, not just the roaches you can see, so we match the method to the source.
Tell us about children, pets, food areas and sensitive items during assessment. Heat-only treatment may suit particular spaces; other infestations need baiting, residual treatment or a combination. We explain preparation, access and return-to-use requirements for the selected method.
A plan for the assessed cockroach activity, with treatment and warranty scope explained before work begins.
We inspect cockroach activity, hiding areas and access, then recommend suitable baiting, residual treatment, heat or other targeted work.
Treatment targets the assessed hiding areas. Follow the preparation and aftercare instructions, and report continuing activity so the team can advise on follow-up.
Eligible cockroach treatment includes a 3-month warranty. The quote confirms covered areas, conditions and the follow-up process.
Cockroaches hide in drains, cabinets, appliances, vehicles and service gaps. The final highlighted method is used when the inspection calls for broader coverage.

Professional residual insecticide applied to suitable travel paths, cracks, cabinets, drains and harbourage points.
Why it helps: Provides immediate knockdown and a residual barrier for appropriate crawling-pest zones.
Professional bait placed strategically for cockroach, ant and colony behaviour, including sensitive food-preparation areas.
Why it helps: Bait-sharing can reach hidden colony members with minimal spraying and low disruption.

Fine-mist treatment for suitable larger spaces, movement zones, drains and areas where even coverage is needed.
Why it helps: Reaches inaccessible areas with reduced downtime when site conditions suit fogging.

Chemical-free heat treatment for suitable cockroach cases involving eggs, hidden harbourage or sensitive spaces.
Why it is more extensive: Heat reaches concealed harbourage and egg-stage activity without chemical residue. It is suitable for sensitive spaces and eligible heat treatment includes the documented 3-month warranty.
Careful planning, clean work and clear communication from the first WhatsApp message to the final check.

Small, light brown cockroaches about the length of a fingernail that run out of kitchen cabinets or from behind the fridge are usually German cockroaches, which live and breed indoors. A colony inside the kitchen needs baiting and residual treatment at the harbourage; visitors from the drains need the drain and the entry routes treated and sealed.
When you see cockroaches repeatedly, see them in the day, find droppings or egg cases, or have them in a kitchen or food business.
Small dark droppings like ground pepper, smear marks along edges, and brown egg cases about the size of a grain of rice.
Leave bait placements alone and do not spray near them. A few sightings in the first days are expected; report sightings that continue past the follow up period or appear in new areas.
Treatment of the kitchen, drains and harbourage found at the assessment, with a 3 month warranty on eligible treatment.
Mobile ULV fogging at your carpark, from $150 for a sedan or hatchback plus $20 to $40 transport, usually 1.5 to 2 hours. See car fumigation.
Scheduled visits planned around service hours, with baiting, drain treatment, proofing and reports for SFA audits. See commercial pest control.
More detail in how to get rid of cockroaches and what to expect after treatment.
Tell the operator exactly where the signs appeared: on the floor nearby, around the outside, or apparently inside a food or electrical compartment. A sighting near an appliance does not establish that it is faulty or must be discarded. Photograph accessible external signs without moving a heavy appliance or opening its casing. Ask what kitchen access and treatment the quotation covers, and confirm any appliance inspection, cleaning or repair with the appropriate provider. Do not assume a general pest product is suitable for an appliance compartment; follow the specific product and manufacturer instructions rather than using spray or heat as a test. Read the detailed guide.
Do not spray an appliance merely because an insect was seen nearby. A general pest product should not be assumed suitable for a food or electrical compartment. Record the location and ask about the appropriate pest assessment and appliance handling. See the appliance cockroach guide.
Timing depends on the infestation and selected method. We assess hiding areas and access before confirming the visit length, preparation and any follow-up. Heat treatment may be suitable for some cases; one visit is not a universal guarantee.
Eligible cockroach treatment includes a 3-month warranty. Your quote confirms the covered areas, conditions and follow-up process.
Homes, vehicles and businesses across Singapore.
A heat-only option is available for suitable assessed areas. Some infestations need baiting, residual treatment or combined methods. We confirm the proposed method and the preparation and re-entry requirements before treatment.
Depending on activity and harbourage, we may use indoor residual spray, gel baiting, drain treatment, foam injection or heat treatment. The chosen method fits the pest pressure, eggs, voids, vehicle or sensitive-space conditions.
Heat treatment is used for suitable cockroach cases where egg-stage control, hidden harbourage or sensitive spaces need a chemical-free approach. Eligible heat treatment has the documented 3-month warranty.
Heat treatment is an assessed option for suitable cockroach cases, including egg-stage concerns. The team confirms the treatment area, preparation and return-to-use requirements. Report continuing activity so follow-up can be assessed.
Yes. We assess ants and flies together with cockroach activity, then use the right method such as baiting, source reduction, residual treatment, drain treatment or ULV fogging.
Yes. Four Solutions provides professional cockroach treatment and removal services across Singapore for homes, HDB flats, condos, offices, kitchens and F&B outlets, using fast chemical knockdown, gel baiting, drain treatment or chemical-free heat treatment depending on the situation.
Cockroach treatment is quoted after a quick assessment because the scope depends on the property size and how severe the activity is. Message us with your situation for a fast quote, or see our pest control cost guide.
No treatment prevents every future entry. Four Solutions assesses the hiding places, suitable treatment and conditions supporting the activity, then explains prevention advice and follow-up. The quote confirms the covered areas and any eligible warranty.
Height does not keep them out. Cockroaches travel up through rubbish chutes, drainage lines, pipe risers, lift lobbies and shared walls, and they can be carried in with boxes, groceries and second-hand items. A high-floor unit can still have activity if there is a food or moisture source and a way in.
No treatment makes a home permanently roach-proof, but we can make it far less attractive to them. After treating the current activity, we check drains, gaps, pipe entries and cabinet voids, and advise on sealing, food storage and moisture control so new roaches have fewer ways in and less reason to stay.
