Which roach is most likely to be found around grass and leaves?

• A. German
• B. Australian
• C. Oriental
• D. American

Answer: (B)

Outdoor habitat preferences of roaches are being tested here. The Australian cockroach is commonly found outdoors in warm, humid environments, and it thrives around grass, leaves, mulch, and other vegetation. That outdoor, leaf-litter association is what makes it the most likely to be seen around grass and leaves. In contrast, German roaches are typical indoor pests found in kitchens and bathrooms, Oriental roaches prefer damp, dark areas like basements and crawl spaces, and American cockroaches are often tied to human structures such as sewers and basements. So the Australian cockroach best fits the outdoor, leaf-litter context.
