Viscosity of cockroach feces was peculiar to the cockroach species, no matter what kinds of foods consumed. The brown-banded cockroach, Periplaneta brunnea and the Japanese cockroach, P. japonica deposit solid feces on the floor of the test arena when they fed on mayonnaise, yogurt, condensed milk, banana or fermented soybean (Nattou). The feces of the smoky-brown cockroach, P. fuliginosa, the American cockroach, P. americana and the German cockroach, Blattella germanica tends to stick to the filter papers when they feed on the same above-mentioned foods. The feces of the latter three species has tendency to stick on the surfaces of filter papers. There were many feces when they fed on fiber-rich foods, such as banana or fermented soybean (Nattou) compared with being fed non-fiber foods. When they fed on water only, the feces were small and distorted.
