Roaches require a multi-pronged approach. Cleaning up as you are doing a good first step. Generally, they are around because there is food, water, and shelter available. Cleaning up can help reduce these resources. Roach motels are excellent for monitoring the population to see if your efforts are helping. Borax sprinkled in the drawers or cabinets is not as effective as mixing up a solution of borax and sugar in water. Roaches drink a lot of water and sugar makes it more attractive so the combination left in shallow containers where you find them is helpful.
