Cockroaches can contaminate food products with their bodies or their waste products; they may also leave a disturbing odor in areas where infestation has taken place. Foraging cockroaches can also be vectors of disease, depositing germs or bacteria in areas that they infest and causing attacks of asthma in some people prone to reactions to cockroaches.
