Call any pesticide service company or buy a suitable pesticide from shops in vegitable market or any agriculture/gardening company and spray all into beds, sofas, furnitures, cup-boards, etc. It takes only half/one hour to kill all. Yes you have to dilute the chemical. This was done by my workers in another GCC country and it works 100% for the purpose.
Well! It is found in all GCC countries and is difficult to eridicate as the municipalities do nothing to get rid of it & in particularly low earning persons are the victims of rich class, as they are dumped to get their countries developed by paying too less to their efforts.
