How to verify a company before anyone sprays your kitchen
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.
