Asian roaches differ from German roaches in that

• A. Asian are much larger
• B. German are good flyers and attracted to lights
• C. Live outdoors and are attracted to light
• D. They differ by color patterns

Answer: (C)

The key idea is how habitat and behavior differ between these two roach species. Asian roaches are primarily outdoor insects; they’re commonly found around exterior lights and vegetation and tend to stay outside rather than congregating indoors. German roaches are the classic indoor pest, thriving inside structures like kitchens and bathrooms. So recognizing that Asian roaches live outdoors and are attracted to light helps you distinguish them from German roaches and guides you toward appropriate control measures (focusing on exterior areas and entry points for Asian roaches versus inside sanitation and sealing for German roaches). Color or size differences aren’t reliable, and German roaches aren’t known for being strong flyers, so that option isn’t a good cue.
