Call an exterminator. Home remedies don't work and you will never truly be rid of them if you don't. So sorry!
Boric Acid works best in my experience. A decent second, if pets or kids is a concern, is diatomaceous earth. Either will need to come in contact to be effective.
We set off roach bombs inside, then sprayed out side perimeter with Home Defense. All gone. Got at home depot.
Found this product on Amazon a few years back. As a apt manager I will SWEAR by this stuff. Takes a few days for 'knock down' - but once they eat it they go back to the nest and die, others eat them, and they die, and on and on.... can be 'hidden' away from kids and pets so only the roaches get to it. I put it out once every 2 years or so -
