Bedbugs do not have nests like ants or bees, but do tend to congregate in habitual hiding places. They 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> Bedbugs can travel at the rate of 3 feet per minute and 100 feet in one night, but they tend to live within 8 feet of where people sleep. They appear to have an affinity for wood and fabric more so than metal or plastic. Bedbugs 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 eggs and instar nymphs are especially hard to detect.

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 are eggs and eggshells, the brownish molted skins of maturing nymphs and the bugs themselves, though these may be hidden more deeply. 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, can be very effective.<ref>[http://www.ca.uky.edu/entomology/entfacts/ef636.asp BED BUGS]</ref>

Cold temperatures below 55 degrees stop bed bug development and egg production,<ref>http://www.bedbugsite.com/faq.php</ref> however, bed bugs are remarkably resistant in almost every sense of the word, and are comfortable within all but the extremes of most inhabitable climates. They can survive freezing temperatures (32°F) for days and tolerate much lower temperatures (5°F) for short periods. Their upper lethal temperature is 120°F causing death within minutes, but longer exposures to temperatures above 113°F are also lethal. They have a wide humidity tolerance range but tolerate dry climates better than humid.<ref> http://www.michigan.gov/documents/emergingdiseases/Bed_Bug_Manual_v1_full_reduce_326605_7.pdf</ref>
