American roaches favor a ______ environment.

• A. Cold and dry
• B. Warm and moist
• C. Cool and dusty
• D. Brightly lit

Answer: (B)

American roaches thrive in warm, moist environments. They need steady warmth and humidity to support their metabolism, development, and hydration, so you’ll typically find them in places with moisture and food near human activity—kitchens, bathrooms, basements, and sewers. Cold or dry conditions are uncomfortable and reduce their survival chances, and while bright light isn’t preferred by roaches (they tend to hide in dark, sheltered spots), the key factor describing where they like to live indoors is the combination of warmth and moisture.
