The phrase to listen for is 'municipality-approved chemicals'. Approved residential products in the UAE are mostly modern pyrethroids, insect growth regulators and gel baits: compounds with low mammalian toxicity at label rates, designed to break down within hours or days indoors. A legitimate technician can tell you the product name, show you the label in Arabic and English, and produce a safety data sheet if you ask.

The most serious violations involve fumigants, above all aluminium phosphide tablets, which release phosphine gas. The product is restricted to licensed agricultural and warehouse fumigation under strict controls and is banned outright in residential settings across the emirates. It has caused fatalities in the region when used illegally in flats and villas, because the gas travels through wall cavities, drains and AC ducting into neighbouring units while occupants sleep. Enforcement tightened sharply after residential incidents, and municipalities now treat illegal fumigation as a criminal matter, not a licensing slip.

Verification takes five minutes and legitimate companies expect it. Ask for the trade licence number and check that the activity list includes public health pest control services, not just cleaning or building maintenance. Ask for the municipality pest control permit for the emirate you live in, since a Dubai permit does not automatically cover work in Sharjah or Ajman. Ask which products will be used by name, and whether the technician carries a municipality approval card.

Then ask two questions that separate professionals from improvisers. First: what is the re-entry time for this treatment with children and pets in the house. A trained technician gives a specific answer tied to the product, usually somewhere between immediately for gel baits and a few hours of ventilation for sprays. Vague reassurance that 'it is completely safe, no problem' is a warning sign, because no responsible operator describes a pesticide that way. Second: what does the service warranty cover and for how long, in writing.

Bedbugs are the pest where cutting corners costs the most. They hide deep in mattress seams, bed frames, skirting boards and behind headboards, and they have developed resistance to many common sprays. A single quick spray visit typically kills the exposed insects, scatters the survivors into adjacent rooms and leaves the eggs untouched, which is why the infestation appears to vanish and then returns worse within weeks.

The gold standard is heat treatment: raising room contents above roughly 45 to 50 degrees Celsius for a sustained period, which kills adults, nymphs and eggs in one pass, including inside furniture where no chemical reaches. It requires specialised heaters, careful monitoring, and preparation such as removing heat-sensitive items, so it costs more than spraying and sits at the upper end of residential pricing. Chemical programmes can still work, but only as a series of two or three visits spaced to catch newly hatched insects, combined with mattress encasements and thorough vacuuming.
