The problem isn't your apartment, it's everyone elses' that live around you. I first saw roaches when I moved to Korea, my apartment was spotless, my neighbors' not so much. I would open drawers in my desk and they would be crawling around. No food anywhere to be seen. Didn't matter. At least they were small. Now I deal with 4 inch long behemoths in a warm climate at least once every few months. I swear you can hear them breathing.
