Can you tell me how to get rid of german roaches? I've had them for the past two years and I keep spraying and spraying but they never seem to die. I know I have killed a lot but after a few weeks they're back again. The main problem seem to be in my kitchen cabinets. It's really tough to spray in there because I have to take everything else out beforehand. Is there any way I can treat this area better and with less effort? I just wan these roaches gone.
