Have you ever tried Combat roach bait traps?

These have worked for me in the past, in another city. You have to buy A LOT of them, preferably different sizes. Stick the regular size ones along the baseboards, every 3 feet or so. Get bigger ones and put them on the inside of the kitchen cupboard doors, reach in by the side of the refrigerator wall and put some there.

Buy as many traps as you can afford, just get an insane amount and put them everywhere. This actually worked for me when I lived in NY. Good luck.
