Cockroaches need food and water to survive. That is why kitchens and bathrooms are areas where we commonly see cockroaches. Food, including pet food, or water anywhere in the home will attract roaches, so immediately wash soiled dishes, throw away discardable food containers, and remove standing water from all rooms. Keep trash in closed containers, and keep food covered and put away. Discard grocery bags, newspapers, cardboard boxes, and other clutter.
People tend to eat where they watch television.
As a result, cockroaches and cockroach remains are frequently found in living rooms, family rooms, and bedrooms. You will find cockroaches any place where food is consumed and crumbs are left behind. These areas will need to be vacuumed or swept to get rid of food crumbs.
