Bed bugs probably received their common name from their habit of feeding on humans while they sleep in their beds.
Bed bugs have also been called "red Coates," "mahogany flats," and "wall-lice."
Sign of Bed Bugs
Small red to reddish brown faecal spots on mattresses, upholstery or walls.
Molt bed bug skins, their white, sticky eggs or empty eggshells.
Very heavily infested areas may have a characteristically sweet odour.
Red, itchy bite marks, especially on the legs, arms and other body parts exposed while sleeping.
Behaviour of Bed Bugs
Female bed bugs lay one to five eggs per day, or an average of 540 eggs in a lifetime. They typically lay their eggs in cracks or rough surfaces.
Bed bug nymphs grow to full adulthood in about 21 days and go through five stages of development before they reach maturity. A bed bug will molt once during each stage of development, though a blood meal is required for a molt.
An adult bed bug can live for several months without a blood meal. Bed bugs are attracted to the carbon dioxide emitted by their hosts. They tend to feed at night on bare skin that is exposed while sleeping.
They are opportunistic insects and will consume a blood meal during the day, especially in heavily-infested areas. Although bed bugs prefer to feed on humans, they will feed on other warm-blooded hosts as well.
Bed bugs usually require 5-10 minutes to engorge with blood. They feed by inserting two hollow, beak-like feeding tubes into their host. The first tube injects the bug's saliva, which contains anaesthetics to numb the feeding area. The second tube draws 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. The queen emits a scent that makes all the workers behave in the way they do.
Where to Find Bed Bugs
Bed bugs are excellent hitchhikers and are easily transported. They will hide in suitcases, boxes and shoes to be near a food supply. They like to hide in small cracks and crevices close to a human environment. Bed bugs are most often found in bed parts, such as mattresses, box springs and folded areas. They can also conceal themselves behind baseboards, wallpaper, upholstery, picture frames, electrical switch plates, and in furniture crevices.
Beg bugs are known to survive in temporary or alternative habitats, such as backpacks and under the seats in cars, buses and trains. Single family homes, multi-family housing, apartments, hotels, hospitals, schools and college campuses, office buildings, retail stores, movie theatres and even public transportation.
Residual spraying at all internal perimeter of the infested area.
