Please....apartments have roaches, that is a fact. They go from one apartment to the next when the bug man comes. That is fact. They just hide in some places better than others.
Go to the store and buy some Boric Acid Powder and squirt it behind the appliances and under the sink, behind the drawers, etc...everywhere there is a crevice or opening. That should take care of any issue of roaches.
I have had them so bad that watching "Welcome To Joe's Apartment" was like a homecoming. I had bought a plant at TG&Y and then ended up having emergency knee surgery from a softball injury. I had left the plant sitting on my coffee table and when I came home the whole place was infested. The bug man came month after month after month. I could get up in the middle of the night and flip on the light. It was like the floor had been painted dark there were so many roaches.....it was disgusting. Finally the bug man came back and he talked to me, asked me thoughtful questions...where did I see the most bugs, did I think they had a nest somewhere in particular, good questions. I told him I felt like they were around the coffee table the most. He got his bug spray tank and had me go out on the landing. He sprayed the exposed sides and top of the coffee table then flipped it up and OH MY STARS!!!! there was a huge nest. He saturated it and that month all my bugs died. I did not have roaches ever again. But I did also use the Boric Acid Powder all the time too.
Roaches happen. They can't be helped especially in apartment situations where they can hide in the walls and go to a different apartment when one is sprayed and the ones around it are not.
