The female produces an average of five eggs cases (oothecae) in a lifetime. The first three contain 28 eggs each, with later oothecae containing far less. Early instar nymphs are yellowish-cream in color. Later instars appear darker in color but are still lighter than German cockroach nymphs. Developmental time from egg to adult is about 70 days with nymphs going through five to seven molts. Adults live about 100 to 150 days.
This species lives outdoors and feeds on decaying vegetation. It often comes into structures seeking moisture during dry periods and populations may be found in irrigated garden or vegetable areas. Originally native to south Asia, it is now found across the southwestern U.S. to Louisiana.
