Bed bugs feed by piercing the skin with an elongated beak through which they withdraw blood. Feeding takes about 3 to 10 minutes, yet the person seldom knows they are being bit. Bed bugs normally do not reside on people like head or body lice. Immediately after feeding they crawl off and reside elsewhere to digest their meal. Symptoms after being bit vary with the individual. Many develop an itchy red welt or localized swelling within a day or so of the bites. Others have little or no reaction, and in some people the reaction is delayed. Unlike flea bites that occur mainly around the ankles, bed bugs feed on any skin exposed while sleeping (face, neck, shoulders, back, arms, legs etc.).
A common concern with bed bugs is whether they transmit diseases. Although bed bugs can harbor pathogens in and on their bodies, transmission to humans is considered unlikely. Their medical significance is chiefly limited to the itching and inflammation from their bites. Though not known to carry diseases, bed bugs can severely reduce the quality of life by causing discomfort, sleeplessness, anxiety, and embarrassment.
