Common Bedbugs, Cimex lectularius (left) & Tropical Bedbug, Cimex hemipterus (right)
Ectoparasites which only feed at night. Bedbugs spend most of the time hiding/resting in the habitat. They only approach a host when they intend to have a blood meal. Bed bugs feed for 3 to 5 minutes until they are fully engorged and drop off from the host. They will hide themselves up in their habitat for few days to digest the meal. If they seek for a blood meal, they will leave the habitat to look for new host. If no food is available, the new nymphs may live for several weeks in warm weather, or several months in cool weather. Bedbugs remain alive for 2 months or longer without food.
