The apartment complex my sister use to manage had monthy exterminators come in and spray the whole complex to avoid problems just like this. If you move, be careful that you don't take them with you in the things you move.

In the mobile home park I live in, people come and go... Twice I have had those pesky little things start coming into mine after someone new moved in. I used Roach Pruff to get rid of them both times. It is a powder and I put it in all cracks inside, under my mobile home outside and on disposable paper plates under dressers, stove, refrigerator and stuff where my babies couldn't get into it. Working like I do, I would also put some on a paper plate on my kitchen counters and on the kitchen floor.. In no time, my problem would be gone. This stuff works good, even the worst infestation will be gone with in 3 months if used and left there. You may want to check in your area and see if you can get it there. Roach Pruff, in a yellow can, about $13 the last time I bought it and it WORKS.

I am highly allergic to the things and I can NOT live where they do...ewwwww! My allergy doctor told me they crawl away and die, they decompose and get into the air and you breath it in and never see it.

You could easily treat your own apartment but they will keep coming in as long as all the neighbors still have them. That whole complex needs to be treated!
