Good hygiene is the key to keeping cockroaches out. It denies them a food source and makes them easier to spot. All cracks, crevices and other building problems that could provide a dark enclosure for cockroaches should be repaired as quickly as possible. Pipe work should not be boxed in as it provides an excellent hiding place for them.
