First of all, definitions are in order.
Bedbugs are small, nocturnal insects from the Cimicidae family, measuring just 4 to 7 mm. Flat and oval, they’re also reddish-brown in color. However, if they’ve just fed on a person, their shape will be more like a torpedo, and they’ll be more red in color. Young bedbugs are a more translucent white-yellow color. Even though they’re tiny, they can often be easy to spot.
