Here are Some Tips on Distinguishing Between Two Types of Cockroaches.

Since their discovery in the U.S., the Asian cockroach has been frequently confused with its German cockroach cousin. Uncovered in Lakeland, Florida in 1986 by a professional pest control operator, the Asian roach was initially identified as a German roach. However, peculiarities in its behavior led to the discovery it was not German, Blattella germanica, as originally believed, but Blattella asahinai, the Asian cockroach. Fortunately, the NJ bed bug specialists are experts at identifying these pests.

Nearly Identical to German Roaches, Asian Roaches Differ in the Following Ways:

Habitat
The primary habitat of Asian roaches is outdoors in shaded or composted areas, where fresh plant litter accumulates.

Wings
Asian cockroaches have a longer, narrower wingspan than Germans, with wings extending past the tip of their abdomen.

Flight
Unlike the German cockroach, Asian roaches are strong fliers. They are most active after sundown, but will take flight in daylight if disturbed.

Dorsal Features
When viewed from above, the stripes on the Asian roach are darker and more defined than those on the German roach.

Underbelly
The abdominal midsection of the Asian roach appears white, while that of the German roach appears lightly pigmented.

Egg Capsules
The egg capsules and nymphs of the Asian cockroach are smaller than those of German cockroaches.
