Bed bugs feed mainly on the blood of

• A. Dogs
• B. Humans
• C. Rodents
• D. Birds

Answer: (B)

Bed bugs are hematophagous insects that rely on blood meals to grow and reproduce, and in typical indoor settings they are most closely associated with humans. They are adapted to feed on people, especially at night when skin is exposed and accessible. They locate hosts using cues like body heat and carbon dioxide, which are most abundant around sleeping humans, making people the primary source of blood. They can bite other warm-blooded animals such as dogs, rodents, or birds if a human host isn’t nearby, but these encounters are less common and don’t reflect their normal feeding pattern. So, humans are the best answer because bed bugs’ feeding behavior is strongly aligned with human hosts in home environments.
