People often wonder why a biting bed bug doesn't wake up its human host when it feeds.

Bed bugs are parasitic insects that feed on the blood of humans and other warm-blooded organisms. Like mosquitoes, they are attracted to carbon dioxide.

Each of those bed bugs needs to feed once per week, which means that you're likely to get bitten every night by multiple bugs if you have an infestation. CC Image courtesy of AFPMB The good news is that bed bugs are not known to have ever transmitted a disease to a human host.
