The American Cockroach is the largest structure-infesting species, seeking shelter in warm, damp areas, especially food preparation spaces. They also prefer hiding during daylight hours. Measuring up to 1.5 inches long, American Cockroaches have red-brown wings with light markings on their thorax.
These aggressive scavengers will eat almost anything and adults live up to 15 months. The female American Cockroach need only mate one time to produce several egg capsules, which contain an average of 13 eggs. American Cockroach nymphs molt 13 times in about 600 days before reaching maturity.
The American cockroach is second only to the German cockroach in abundance. (Factoid Source: Kathryn A. Barbara, University of Florida)
