To prevent cockroach infestations, it is essential to reduce food and water sources as well as known and potential hiding places. If cockroaches have access to food, baits (which are primary control tools) may take longer to provide satisfactory control. Insecticide sprays alone will not eliminate cockroaches.

A few insecticides used for cockroach control are applied as dusts or powders. Most familiar to householders are boric acid and diatomaceous earth.
