German and American roaches have different treatments.
American roaches are more of any outdoor pest and the treatment needs to be outdoors, under the structure (if pier and beam), in attic, walls, etc. Demon WP should work on American roaches in any of these areas, there is no known (resistance) to Demon WP in American roaches that I am aware of. Just be sure that you are treating any possible area where they could be living. If you are missing the crawl space for example, then you won't totally kill them all.

German roaches different story. These roaches are a pest of inside the structure. They live and breed inside cabinets, pantry's, closets, under and behind stoves, refrigerators, dishwashers, etc.

If Demon WP is not working it could be that the roaches are RESISTANT, or basically immune. In that case, you have to use a different product from a different chemical family.
Alpine Pressurized works great as a spray -

The best way to get rid of German Roaches is with a bait such as Maxforce FC Cockroach Gel Bait - http://www.epestsupply.com/product/CH...
This bait works well because the roaches will actually consume each other when dead and this bait will kill other roaches that feed on each other. This is called the "Domino Effect".
In any case, just remember that German Cockroaches can travel from home to home and this can be a problem. American Cockroaches usually are limited in where they travel and usually do not travel as do German Roaches.
