The common bed bug (Cimex lectularius Linnaeus 1758) is an ectoparisite insect (a parasite which lives on the outside of the body of the host) of the family Cimicidae. Bed bugs feed only on the blood of humans and other warm-blooded hosts. Although they have a cryptic behavior and can conceal themselves in tight cracks and crevices, bed bugs are often found in bed parts, such as mattresses and box springs, hence the common name.
Bed bugs like to travel and are good hitchhikers. They will hide in suitcases, boxes and shoes to be near a food supply. They are elusive, nocturnal creatures. They can hide behind baseboards and in cracks, crevices, and folded areas of beds, bedding and adjacent furniture, especially mattresses and box springs. Bed bugs can also hide in electrical switch plates, picture frames, wallpaper and nearly anywhere inside a home, car, bus, or other shelter. Bed bugs usually come out at night for a blood meal. However, they are opportunistic insects and can take a blood meal during the day, especially in heavily-infested areas. Bed bugs usually require 5-10 minutes to engorge with blood. After feeding, they move to secluded places and hide for 5-10 days. During this time, they do not feed but instead digest their meal, mate, and lay eggs.
Bed Bugs like to hide in small cracks and crevices close to a human environment. They can be found behind baseboards, wallpaper, upholstery, and in furniture crevices. Beg bugs are also known to survive in temporary or alternative habitats, such as backpacks and under the seats in cars, busse's and trains.
Although bed bugs can dine on any warm-blooded animal, they primarily dine on humans. Bed bugs do not transmit diseases, but their bites can become red, itchy welts.
