Bed Bugs

Bed bugs are small wingless insects that feed solely upon the blood of warm-blooded animals. Bed bugs seek out people and animals, generally at night while these hosts are asleep, and painlessly sip a few drops of blood. While feeding, they inject a tiny amount of their saliva into the skin–some people develop a sensitivity to the saliva and additional bites may then result in mild to intense allergic responses. Bed bugs are not known to transmit any diseases to humans.
