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 treat the harbourage and entry points so the cockroaches do not simply return.
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.
Not every home wants chemical spray around young children, pets or food. Our chemical-free heat option clears cockroaches and their eggs in a single session using controlled heat alone, with no residue left behind. Where a space needs more, we combine methods, but you always have a low-chemical choice that most spray-only operators do not offer.
Two treatment options, one clear outcome, backed by a warranty.
Fast chemical knockdown, or a chemical free heat treatment, whichever suits your space.
Heat treatment clears eggs in a single session, for homes, vehicles and businesses.
Cockroach treatment is backed by a 3 month warranty for peace of mind.
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, vehicles 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.

Lasting control comes from treating the harbourage and eggs, not only the roaches you can see. We combine gel baiting, residual treatment or chemical-free heat with drain and entry-point checks, then advise on the moisture and food sources that keep drawing them back. Surface spray alone tends to knock down a few while the nest keeps breeding.
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.
