Etymology

Origin of bedbug

First recorded in 1800–10; bed + bug 1

Explanation

A bedbug is like a tiny vampire that lives in mattresses and couches, feeding on human and animal blood. About the size of an apple seed, these insects are especially frightening in large groups. Bedbugs are tiny, flat insects that feed on human and animal blood, usually at night. These pests have coexisted with humans for thousands of years, hitchhiking around the world in luggage and clothing. Despite their name suggesting a preference for beds, bedbugs can also conceal themselves in unexpected places like electronics and behind wallpaper. Their ability to hide and travel with unsuspecting hosts makes them terrifying invaders in any environment.
