The frustrating truth about cockroaches in apartment buildings: your flat is not an island. German cockroaches travel through service shafts, drain lines and wall voids, which is why the tenant who "sprays every month" still has roaches and wonders what they are doing wrong. The answer is strategy, not volume of chemical.
Why spraying alone fails in towers
Surface sprays kill on contact and repel survivors — deeper into the walls and into your neighbour’s kitchen, from where the population re-invades within weeks. Meanwhile the egg cases, which sprays barely touch, hatch on schedule. You are mowing the lawn, not removing it.
What actually works: gel baiting
Professional gel baits placed at nesting and travel points get carried back into the colony and spread through it — including to roaches that never cross a sprayed surface. Municipality-approved gels are odour-free, require no evacuation, and remain active for weeks. One treatment plus a follow-up visit typically collapses an established infestation.
The prevention that keeps them out
Seal the highways: steel wool or sealant around pipe penetrations under sinks, mesh on floor drains, silicone on kitchen skirting gaps. Deny the water more than the food — roaches survive weeks without food but days without water, so fix dripping taps and dry sinks overnight. And check cardboard delivery boxes; they are the taxi service of the roach world.
Know your enemy: German vs American cockroaches
The small (1–1.5 cm) light-brown roaches in your kitchen are German cockroaches — the apartment specialist, breeding indoors year-round, one egg case producing 30–40 offspring, and the species gel baiting targets. The big (3–5 cm) reddish ones that appear near floor drains and balconies in summer are American cockroaches — sewer travellers coming up from the drainage network, less an infestation than an invasion route. The distinction matters because the treatments differ: gel and hygiene for German; drain treatment, mesh covers and trap water for American. A company that asks which you have before quoting is a company that treats rather than sprays.
What professional treatment costs (2026 Dubai)
Municipality-approved gel treatment with follow-up visit: AED 199–350 for apartments, AED 350–600 for villas. Annual contracts (typically 3–4 scheduled visits plus free call-outs between them): AED 500–900 for apartments — the sensible option in older buildings where the reservoir population next door never disappears. Beware two extremes: AED 99 spray-only visits that scatter the colony deeper into the building, and pressure-sold "fumigation" for ordinary infestations that gel handles better without evacuating anyone.
If you are seeing them in daylight
Cockroaches are nocturnal; daytime sightings mean the harbourage is crowded enough to push individuals out — an established colony, not stragglers. The same is true of finding them in bedrooms (far from food, meaning kitchen harbourages are saturated) and of pepper-like droppings inside cabinet hinges and drawer runners. At that stage, add-a-spray DIY has been overtaken by events: the colony is producing faster than surface killing removes, and professional gel plus a follow-up visit is the efficient path back to zero.

Frequently Asked Questions
Do I need to leave my apartment during cockroach treatment?
Not for gel baiting — it is odour-free, targeted and safe for occupied homes, including those with children and pets, with baits placed out of reach. Only broadcast spray treatments need a few hours away; a modern German-cockroach programme rarely requires them.
Why do cockroaches keep coming back after pest control?
Usually because the treatment was spray-only (killing foragers, missing the colony and egg cases) or because the building reservoir re-invades through unsealed pipe gaps and drains. Gel baiting plus physical sealing addresses both — and a written re-treatment guarantee covers the gap between visits.
How much does cockroach pest control cost in Dubai?
Professional gel treatment with a follow-up visit costs AED 199–350 for apartments and AED 350–600 for villas with Dubai Municipality-approved products. Annual protection contracts run AED 500–900 for apartments and include scheduled visits plus free call-outs.
