Hi Sherry: Check this site, it may help:
Call an exterminator. Roaches are too hard to deal with on your own. They can spray in places you can't reach.
I agree with Em. We've set off roach bombs and sprayed around the outside of house with Home Defence. That worked well.
I used glue traps ,bombs every week ,that’s only if you afford a exterminator I got rid of them I a few months
Boric acid powder. It’s inexpensive, and effective. The roaches carry it back to the nest, and it kills all of them.
Boric acid if you have no kids or pets. Earth grade diatomaceous earth if you do.
