When bedbugs bite, like mosquitoes, they inject an anesthetic that prevents the host from feeling the bite, and an anticoagulant for blood flow. Bedbugs are normatively nocturnal, though they can bite during the day or with light, but they usually occur while people are sleeping.  Feeding takes three to 10 minutes, depending on maturity, and immediately after feeding the bug crawls off  to digest their meal in a safe place.  Bite marks can be random or in a straight line.<ref>http://www.cdc.gov/nceh/ehs/Publications/Bed_Bugs_CDC-EPA_Statement.htm</ref> Anecdotal evidence suggests they wait until the host is in their deepest part of sleep, usually 3-5am.

Bedbugs do not have nests like ants or bees, but do tend to congregate in habitual hiding places. Bedbugs can travel over 100 feet in one night, but they tend to live within 8 feet of where people sleep. Bedbugs appear to have an affinity for wood and fabric more so than metal or plastic. They hide during the day in such places as mattresses seams, box springs, bed frames and headboards, dresser tables, cracks or crevices, baseboards, behind wallpaper, and under any clothes, clutter or objects around a bed. Their small flat bodies allow them to fit into the smallest of spaces and they can remain in place for long periods of time, even without a blood meal. Bedbugs are easily and usually transported from place to place by people as they travel, and nymphs are especially hard to detect.

Bedbugs are attracted by the carbon dioxide and (secondarily) the heat and that a people generates, and they will feed only through a membrane.<ref>[http://www.faqs.org/periodicals/201006/2054573271.html ''Bed Bugs: The Pesticide Dilemma'']</ref> They can travel over 100 feet in one night, but they tend to live within 8 feet of where people sleep.

In addition to bits, bedbugs are made evident by areas are marked by dark spotting and staining, which is the dried blood excrement of the bugs. Dark spots of dried bed bug excrement are often present along mattress seams or wherever the bugs have resided. Also present will be eggs and eggshells, the brownish molted skins of maturing nymphs and the bugs themselves. Less often one may see rusty or reddish blood smears on bed sheets or mattresses from crushing an engorged bed bug. Some companies are beginning to use canines for detecting infestations, which, if properly trained, have been very effective.<ref>[http://www.ca.uky.edu/entomology/entfacts/ef636.asp BED BUGS]</ref>
