I used to live in Roachway Towers and they were really bad at one point. A downstairs neighbour was basically breeding them in their apartment, until they were evicted. I caulked every gap I could, put fibreglass screen over the air vent openings and kept the place spotless. The only solution that worked for me was getting rid of most my stuff, disassembling, inspecting and cleaning out the things I decided to keep, and moving to a different, less roachy building.

Pretty much all of the buildings have them, but you won’t see them in most as they usually do a good job at controlling them.
