Pest control is a licensed trade, not a man with a spray can
In the UAE, pest control sits under public health law, not general maintenance. At the federal level, the Ministry of Climate Change and Environment (MOCCAE) registers every pesticide that may legally be imported, sold or applied, and it maintains a list of restricted and banned substances. No company, however large, is allowed to use a product that does not appear on the approved register, and residential use faces tighter limits than agricultural or industrial use.
This matters because pesticides are dose-dependent poisons. The same active ingredient that is safe at label concentration in the hands of a trained technician becomes dangerous when an unlicensed worker doubles the mix to make the treatment 'stronger'. The licensing system exists to keep untrained hands away from concentrates, and every shortcut around it transfers risk directly onto your household.
