Which roach is a good flyer, both feral and peridomestic (living in and around human habitation)

• A. Asian
• B. American
• C. Brown
• D. German

Answer: (A)

Flying ability varies by roach species, and this affects how they disperse around homes. The Asian cockroach has wings that function very well for sustained flight, so adults readily take to the air in outdoor areas and can move between yards and into buildings. This makes it effective at establishing both feral populations and peridomestic infestations. In contrast, German and brown-banded roaches are generally poor fliers and tend to spread more by crawling, and American cockroaches can fly but are less consistently observed flying in peridomestic settings. So the Asian cockroach is the best match for a good flyer in both feral and peridomestic contexts.
