Every apartment block has roaches, I’m not naive. But to get rid of the ones in mine I put a teaspoon of borax near the dishwasher kick plate and blew it under with compressed air. Sprinkled some around the perimeter of the cabinet beneath the kitchen sink.
Have not seen a roach in 10 months.
Edit: don’t try to bait food with borax, they won’t eat it, just get it on the walking paths. You want them tracking it into the hive where they all clean it up like cats and die because to an insect it’s like eating knives.
Borax as insect repellant/ murderer.
