Typically found indoors in temperate climates; hides in cracks and crevices near sleeping areas, such as mattresses, box springs, bed frames, furniture, behind baseboards, and under wallpaper.
Diet & Feeding
Hematophagous (blood-feeders); they feed exclusively on the blood of mammals, preferring humans, but will also feed on pets.
Behavior Patterns
Nocturnal and elusive, emerging at night to feed on sleeping hosts. They are attracted to warmth and carbon dioxide. After feeding, they retreat to hidden harborage sites where they digest and reproduce. They do not fly or jump but crawl quickly.

While not known to transmit diseases directly, infestations can cause significant psychological distress, anxiety, and insomnia. Can cause allergic reactions in some individuals. Benefits: No known benefits to humans or the domestic ecosystem.
