Asian Cockroach

The term “Asian roach” typically refers to the Asian cockroach (Blattella asahinai). This cockroach species is often confused with the German cockroach (Blattella germanica) due to their similar appearance. However, they have some distinguishing characteristics that can help you identify the Asian cockroach:


  • Asian cockroaches are small to medium-sized cockroaches.
  • Adults typically measure between 0.4 to 0.6 inches (10 to 15 millimeters) in length.


  • They are light tan to light brown in color, often with a slightly yellowish or grayish tint.
  • Unlike German cockroaches, Asian cockroaches lack the distinctive dark stripes on the pronotum (the plate-like structure behind the head).

Body Shape:

  • Asian cockroaches have a slender, oval-shaped body.
  • The body is flattened, making it easier for them to squeeze through small cracks and crevices.


  • Asian cockroaches are strong fliers and are attracted to outdoor lights, which is why they are sometimes referred to as “flying cockroaches.”
  • They are primarily outdoor insects but can be drawn indoors, especially when outdoor conditions are favorable for them.


  • Asian cockroaches are commonly found in outdoor environments, such as gardens, lawns, and vegetation.
  • They are more commonly encountered in warm, humid regions and are less likely to infest indoor spaces.


  • Asian cockroaches have a typical cockroach lifecycle, including egg, nymph, and adult stages.
  • They reproduce outdoors and lay their egg capsules in moist soil.

It’s important to note that the Asian cockroach is primarily an outdoor pest and is not as common indoors as the German cockroach, which is a well-known indoor pest. If you suspect an Asian cockroach infestation indoors, it’s advisable to consult with a pest control professional for proper identification and treatment, as the control methods for outdoor and indoor cockroach species may differ. Additionally, outdoor lighting management can help reduce their attraction to your property.
