Bedbugs: Facts, Bites and Infestation
By Megan Gannon, Live Science Contributor | May 2, 2017 05:12pm ET
Bedbugs lurk in cracks and crevices and they've been living on human blood for centuries. Though they aren't known to transmit disease or pose any serious medical risk, the stubborn parasites can leave itchy and unsightly bites. However, bedbugs don't always leave marks. The best way to tell if you have a bedbug infestation is to see the live, apple-seed-size critters for yourself. Unfortunately, once bedbugs take up residence in homes and businesses, they can be difficult to exterminate without professional help.
Appearance, lifestyle and habits
Bedbugs are flat, round and reddish brown, around a quarter-inch (7 millimeters) in length. The ones that typically plague humans are the common bedbug Cimex lectularius and the tropical bedbug Cimex hemipterus.
