Bed Bugs - Pictures

Identification:
Bed bugs are about 1/4" long when full grown,
reddish-brown in color, wingless, and can vary between
somewhat flattened (unfed) to "football"-shaped after
feeding.

Bed bug bites
are usually painless
Bed bug bites are painless and generally cause red
and itchy lesions, somewhat like marks from bad
mosquito bites. Unlike many insects that feed on human
blood, bed bug bites do not transmit diseases and they
are not otherwise dangerous. Secondary infections
caused by scratching to relieve the itch are common.
Bites can occur in lines or clusters.

Bed bugs
swell up during feeding
Bed bugs expand or "inflate" somewhat as they feed
and ingest blood (see photo right). After feeding bed
bugs will usually retreat to their hiding places to
digest the blood. The black, greasy stains that are
found in the hiding places are digested blood.
