Don't waste Your money with trap and sprays. Put down a thin layer of Boric Acid around your kitchen and bathroom walls. It's not toxic to humans or pets but it is deadly to cockroaches. The cockroaches will carry it back to their nest when it attaches to their bodies thus helping to kill them where they live. Your roach problem should be gone in about a week or two. You can purchase Boric Acid at any hardware store and it comes in bottles with applicators that can be used for dispensing it. Say goodbye to your roaches!
