Cockroaches keep coming back to a Dubai apartment because they move between flats through shared plumbing risers, wall voids and service ducts, so treating one unit alone rarely holds. Under Article 16 of Dubai's Law No. 26 of 2007, the landlord carries maintenance and repairs during the lease unless your tenancy contract says otherwise.
You paid for the treatment. Two weeks of quiet, and then the same brown shape crossing the same kitchen tile at 2am. Most homeowners assume the company cut corners and go looking for a cheaper one, which starts the cycle again. In a tower, the company usually did its job — the flat sharing your kitchen wall, or the one directly below yours, was never treated at all, and the waste pipe runs straight through the slab between you.
So the useful questions are not about sprays. They are about who owns the route the cockroaches are using, and who has to pay to close it. This guide answers both from the actual legal text and from Dubai Municipality's own published remit, then gives you the script to get the whole riser treated instead of your flat alone.

Why are there so many cockroaches in Dubai apartments?
Dubai apartments give the German cockroach — the small kitchen species behind almost every recurring flat infestation — everything it needs without it ever going outdoors. Warmth is constant because the building is air-conditioned all year. Water is constant because of condensation on chilled-water pipes, drain traps and the gap behind the fridge. Food is constant because a kitchen is never perfectly clean at the millimetre scale that matters to an insect the size of a fingernail.
Density does the rest. A Dubai tower stacks dozens of kitchens vertically over one set of risers, feeds them through shared corridors and waste rooms, and often sits above ground-floor food outlets. Every one of those is a source that has nothing to do with how you keep your own home.
Where they actually live matters more than where you see them. Research published in the Journal of Economic Entomology in 2019, monitoring a high-rise apartment building, found traps by the stove and the refrigerator caught significantly more German cockroaches than traps in the cabinet under the sink or in the bathroom. The table below sets out the harbourages that matter in a Dubai flat and what a treatment has to reach in each one.
Who is responsible for cockroaches in a Dubai rental — the tenant or the landlord?
In a Dubai rental the default is the landlord's, and only your own contract beats it. Article 16 of Law No. 26 of 2007 reads: "Unless otherwise agreed by the parties, the Landlord will, during the term of the Lease Contract, be responsible for the Real Property maintenance works and for repairing any defect or damage that may affect the Tenant's intended use of the Real Property." So read the maintenance clause in your own contract first — that clause is the "unless".
One detail almost nobody states: Law No. 33 of 2008 superseded Articles 2, 3, 4, 9, 13, 14, 15, 25, 26, 29 and 36 of the 2007 law. Article 16 was not among them, so the maintenance default still reads as issued. The table below sets out the four articles of Law No. 26 of 2007 that decide almost every cockroach argument in a Dubai rental.
The line falls on cause, not on who noticed first. A gap around the waste pipe, a dry drain trap, an unsealed riser panel or a building-wide infestation is a property defect and points at the landlord. Food left out and stacked delivery cardboard point at the tenant.
Do cockroaches move between flats in a Dubai tower?
Cockroaches move between flats in a tower, and the movement has been measured rather than assumed. The 2019 Journal of Economic Entomology study of a high-rise apartment building found infestations were not distributed randomly: where one apartment was infested, the neighbouring units — adjacent through a shared wall, across the hallway, or directly above or below — were likely to be infested too.
💡 What the building-wide trial proved
After twelve months of coordinated treatment across every unit, the correlation between neighbouring flats across hallways and shared walls disappeared. The researchers concluded that only a comprehensive approach that left no apartment out could be effective, and that vertical movement through utility pipework was the pathway that resisted treatment longest.
Translate that into a Dubai tower and the shape of your problem changes completely. Towers stack kitchens and bathrooms vertically so one riser shaft serves a whole column of flats, which is why the most stubborn route is the one running up and down rather than side to side. A treatment inside your four walls can be done perfectly and still fail, because the population sourcing it never lived in your flat.
The riser is also the honest test of a pest control company. A company that inspects the riser penetration under your sink, asks whether the flats above and below have reported anything, and tells you plainly that a single-unit treatment may need repeating is being straight with you. A company that promises a permanent fix from one visit in a shared building is selling you a repeat booking.
What kills cockroaches in a Dubai kitchen, and what only scatters them?
Gel bait kills a Dubai kitchen population because it works where you cannot reach. A cockroach feeds at the bait point, returns to the harbourage inside the cabinet plinth or the fridge motor housing, and the active ingredient passes through the nest to insects you will never see. Add an insect growth regulator to stop the next generation maturing, seal the pipe penetration under the sink, fix any standing water, and book the follow-up visit — the eggs surviving the first round hatch after it.
⚠️ Supermarket aerosols make a tower infestation worse, not better
A contact aerosol kills the few cockroaches out in the open and acts as an irritant on every surface you sprayed. The rest are driven deeper into the wall voids — and in a shared building, into the flat next door and the one above. Spraying a repellent product over gel bait also stops the cockroaches feeding on it, which disables the one treatment that was working. In a Dubai tower you are not killing the population, you are redistributing it, and it comes back with the neighbours' share added.
Foggers and smoke bombs fail for the same reason at greater scale: the cloud never penetrates the sealed voids where the insects actually live, and it drives the survivors through the ceiling void into a neighbour's kitchen. Ultrasonic plug-in repellers do nothing measurable at all. Aim your own effort at the stove and the fridge rather than the bathroom, because that is where the monitoring data puts them.
Does Dubai Municipality do pest control in homes?
Dubai Municipality does carry out pest control directly, but the published remit is narrower than most residents assume. Its Public Health Pest Control Section states that it runs integrated pest management "especially for disease-transmitting pests, such as mosquitoes, flies, and rodents", and that it performs public health pest control in "public areas and facilities, landfills, markets, wastewater treatment plants, public gardens and parks, horse stables, citizens' homes, ports, airports and others".
Read that list again and notice what is absent. Cockroaches in a rented apartment are neither a disease-transmitting public health pest programme nor one of the listed premises, so a tenant in a Dubai tower should not expect a Municipality crew to arrive and treat the kitchen. For that flat, the Municipality's role is regulatory: it issues the No Objection Certificate a pest control company needs before obtaining its trade licence, regulates and qualifies those companies, assesses their pest control programmes, classifies pest samples and tests pesticide effectiveness.
The section publishes its own contact details for public health pest questions: the toll-free number 800900 and info@dm.gov.ae, with the office in Al Quoz Industrial Area 3 open 07:30 to 14:30, and 08:00 to 13:00 during Ramadan. Use that route for mosquitoes, rodents or a genuine public health concern in a shared area. For the cockroaches in your own kitchen, the practical step is a Municipality-approved private company — our guide to finding and verifying a Municipality-approved pest control company walks through that check.
How do you get a whole Dubai building treated, not just your flat?
Asking nicely by text message achieves nothing, because a building manager cannot act on a complaint that names no defect. Put the shared route in writing and the request stops being about your housekeeping and starts being about the property. The checklist below is the sequence that gets a riser treated.
✅ The five-step escalation that actually works
- Photograph the route, not the insect. Dated photos of the unsealed pipe penetration, the open riser panel or the missing drain trap.
- Email the landlord and the building manager together. Name the defect, name Article 16, attach the photos, and ask for a written reply.
- Ask for the units above, below and adjacent to be included. Cite the shared riser as the reason, not the smell or the fright.
- Get the follow-up date in writing before the first visit. A single visit in a shared building is half a treatment.
- If the landlord refuses and your contract is silent, escalate. The Rental Disputes Centre is the forum for a Dubai tenancy dispute.
Meanwhile, get your own flat treated properly by a company that will say the word "riser" out loud. TaskRight is a verified, zero-commission home services platform in the UAE — every pest control company on it is verified before it can quote, the quotes come to you free, and you hire the company direct with nothing taken out of the job.

Frequently asked questions about cockroaches in a Dubai apartment
Who is responsible for cockroaches in a Dubai rental — the tenant or the landlord?
In a Dubai rental, Article 16 of Law No. 26 of 2007 places maintenance and repair of defects affecting your use of the property with the landlord, unless the tenancy contract says otherwise. A building defect such as an unsealed riser is the landlord's side. Bins, spills and stored food are the tenant's under Article 19.
Can a landlord in Dubai refuse to arrange pest control for cockroaches?
A landlord in Dubai can refuse where the tenancy contract validly shifts maintenance to the tenant, because Article 16 applies only "unless otherwise agreed by the parties". Where the contract is silent and the cause is a property defect rather than your housekeeping, the refusal is contestable and the Rental Disputes Centre is the forum for it.
Do cockroaches travel between flats in a Dubai tower?
Cockroaches travel between flats in a Dubai tower through shared plumbing risers, wall voids, ceiling voids and service ducts. A 2019 study of a high-rise apartment building found infested units clustered next to, across the hallway from, and directly above or below one another, and that vertical movement through utility pipework resisted treatment longest.
Does Dubai Municipality treat cockroaches in a rented Dubai apartment?
Dubai Municipality's Public Health Pest Control Section targets disease-transmitting pests such as mosquitoes, flies and rodents, and lists the premises it treats as public areas, landfills, markets, parks, stables, citizens' homes, ports and airports. Cockroaches in a rented Dubai apartment fall outside that remit, so the route is an approved private company.
Do shop-bought cockroach sprays work in a Dubai apartment kitchen?
Shop-bought aerosols kill the cockroaches in the open in a Dubai apartment kitchen and drive the rest deeper into wall voids and into neighbouring flats, so the visible problem returns larger. Spraying over gel bait also stops the insects feeding on it. Gel bait placed into the harbourage is what reaches the population.
Stop paying twice to kill the same cockroaches
Every repeat treatment you buy for a problem sourced two floors down is money spent on the wrong flat. The cheapest version of this is the one that ends it: a written request that names the shared route and Article 16, and one properly done bait treatment with the follow-up already booked, from a company that inspects the riser instead of fogging your kitchen.
Compare verified pest control companies in Dubai side by side, get your quotes free, and hire direct. Nothing comes out of the job, so the company is working for you rather than for a platform's cut.
