Keep garbage in closed waster containers that you can empty and clean regularly. Store compost buckets in the refrigerator until they are emptied. Feed pets at scheduled times and do not leave bowls of food on the floor. Wipe up cockroach feces with a disposable cloth. Feces contain a pheromone that attracts roaches, and newly hatched roaches feed upon feces of older roaches.
Cockroaches require water, although the brown-banded can live for several weeks with minimal water.
Repair leaks, insulate pipes, and caulk gaps around sinks and tubs to prevent water from getting behind walls. Don't let water stand in houseplant dishes or in the pan under the refrigerator. Cockroaches live inside cardboard and paper bags and can eat the glue that binds them together. Do not store boxes, cardboard, equipment paper, clothes, or containers on the floor, and don't wedge paper bags between appliances or inside cabinets. Replace wooden shelving with plastic or stainless steel, or caulk gaps between pieces of wood shelving, after cleaning and vacuuming.
