As for the small "German" roach, most commonly found in multiple unit residential human dwelling places, the feces looks like tiny specks of black pepper. When a roach infestation occurs the build-up of roach feces and regurgitation will cause the effected area to have a characteristic dank, "septic," unhealthful odor. Such build-up can cause allergic reactions such as sneezing, watery irritated eyes, skin rashes & Asthma. Additionally, roaches & their feces & regurgitaion carry, spread & contain disease causing microbes.
