A bedbug is a wingless, rust-colored insect about the size of an apple seed. Bedbugs are nocturnal parasites, which means they rest during the day and come out to dine on the blood of humans at night. Bedbugs are attracted by human body heat and typically favor feasting on our shoulders and arms (ewww).
During feeding, the bedbug's proboscis pierces the skin of its victim, injecting bedbug saliva (double ewww). Bedbugs typically feed for five to ten minutes at a time. As the little critter fills with blood, its colouring changes from light brown to rust–red.
