Mix Borax (20 Mule Team Borax, found in the laundry section) with boric acid powder (drug store), even amounts of both ingredients. Sprinkle where ever the roaches are a problem and where ever they are getting in the house. Don't use around children or pets. This has worked in some serious roach infestations and it's way cheaper than professionals.
