→Life and behavior: temp kills
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>

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>
As bedbugs become active when sensing human presence, in the 1960s the US Army considered them for use in a portable insect ambush detector or a stationary intrusion detector device.<ref>http://handle.dtic.mil/100.2/AD837100</ref>
