I just moved into a apartment on 3/1 and within a week had roaches. Noticed that there was a hole in the ceiling and waited over 3 weeks for the hole to be fixed. They sprayed and bombed just last week and I am still having issues with roaches crawling around. It will barely be 2 months since I have moved in. I have cleaned from top to bottom, left no food or trash to wake up to roaches still in the house. What can be done?
