In Dubai and other parts of the UAE, it is mandatory to have your food area inspected every six months. But that's not the only way to keep pests at bay. You should also ensure the inside and outside as far as a metre from the exterior of your restaurant has a schedule for insect control and that any areas where food is prepared are disinfected regularly with an approved cleaning agent for the removal of pathogens. When you're first starting out, book in for debug pest control twice a year or four times a year depending on if you're in Dubai or another region like Sharjah.
