Will Bed Bugs Bite While Youre Awake?
Bed bugs prefer to bite humans during the night when they are sleeping and inactive, as their feeding is stimulated by the exhaled carbon dioxide and warmth of sleeping humans. However, if a bed bug is hungry and cannot find a sleeping host, it may bite during the day while a human is awake and active. Most people do not feel the bite itself but will later develop itchy welts or rashes.
