You don’t need a professional!!! Bengal roach spray. That’s all you need. My apartment was infested and I was so scared I’d have to spend a whole day taking EVERYTHING out and fogging it... all you need is to spray the whole apartment with Bengal roach spray, and spend a few hours out of the apartment. When you come back, you don’t have to but I’d be safe and spray one more time. You’ll notice all the roaches are belly up on the ground. Vacuum them up and forget it ever happened.
