I used to live in an apartment complex in Phoenix, and cockroaches were a constant problem.
You have to keep absolutely ALL food in your house sealed at all times.
Call the apartment manager and have them fumigate your apartment.
This will only drive out the cockroaches temporarily, they will go to neighboring apartments.
As soon as those neighboring apartments get fumigated, the cockroaches will go looking for a new home.
I'f you forgot to keep all your food sealed, the cockroaches will return to your place.
It's a constant battle, and in the long term, the roaches win.
