Ok so we got these roachs not the big old ones that fly. but the litte brown ones that look like this http://upload.wikimedia.org/wikipedia/commons/thumb/4/49/Cockroach_closeup.jpg/449px-Cockroach_closeup.jpg

We have had people come spray. and they dident die. So we use begal. and it killed em. But they just came back. Then we use home defense and it dont seem to work. Borax powder don’t seem to either. Were running out of things to try. Were giving up hope. Does anyone know what to do or anything to kill these things they seem impossible to kill.
