Bed bugs primarily feed on blood of which animal group?

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

Answer: (C)

Bed bugs are obligate blood feeders, and in typical indoor infestations humans are their primary source. They live close to where people sleep and take advantage of exposed skin at night, feeding for a few minutes on areas like the face, neck, and arms. This close, frequent access makes human blood the most common and preferred meals.

They can bite other warm-blooded animals if humans aren’t nearby—pets, birds, or other animals might be bitten in some settings—but those hosts are not the usual target when people are present in their homes. The regular, reliable availability of human blood in sleeping areas explains why humans are the primary blood source bed bugs rely on.
