Bed bugs feed mainly on the blood of which host?

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

Answer: (A)

Bed bugs are blood-feeding parasites that rely on a steady blood source to grow and reproduce. In domestic settings, their primary host is humans because we provide a reliable, close, warm blood source, especially at night when people are sleeping. They’re attracted to body warmth and carbon dioxide and typically bite people during the night for short feeding sessions. They can feed on other warm-blooded animals such as dogs, cats, or birds if humans aren’t available, but those are less common in homes, so humans are the main host.
