The term 'Australian' in roach identification refers to which species category?

• A. American
• B. Florida woods
• C. German
• D. Australian

Answer: (D)

In roach identification, common names are tied to specific species. The term “Australian” points to the Australian cockroach, Periplaneta australasiae—a distinct species from the others you might see named in pest control. This naming isn’t about where the roach is found, but about identifying the exact species so you can apply the right control methods. Other named categories refer to different species, such as the American cockroach (Periplaneta americana) or the German cockroach (Blattella germanica), and the Florida woods roach refers to a different outdoor species altogether. So, hearing “Australian” identifies the Australian cockroach as the species category.
