The bed bug is a bloodsucking parasite.
Bed bugs hide during the day in secluded places that are well protected. They are happy to hide in any opening providing it give them enough cover be it fabric, wood, plastic or paper surfaces. They might start quite close to the host's bed, but they will travel far distances for a blood feed. Mattresses are a favourite place for bedbugs they can be found under buttons, in seams, and folds spreading to any part of the bed frame and draws or the underside of the bed. Bed bugs will freely infestation the whole of the bedroom spreading to all the bedrooms in the house. This is particularly true of hotels and other multiple dwellings, bedbugs can contaminate multiple rooms in a home or multiple dwellings in hotels or flats very rapidly.
Bed bugs often occupy hiding places farther away from the bed. They can hide in door and window frames, behind telephone and electrical points, under floorboards, behind plasterboard, in furniture, behind on the wall pictures, in curtains, on curtain poles, wall hangings, drapery pleats, loosened wallpaper, cracks in plaster, and ceiling mouldings
Bed bugs are fast moving insects they move at the speed of an ant, they are nocturnal blood-feeders when their hosts are sleeping. They can gorge as much as 7 times their own body weight in one feed; often over feeding they will spill some blood on bedding. Nymphs may become engorged with blood within two to three minutes, whereas a full-grown adult bed bug will feeds for up to fifteen minutes, moving along its hosts body at will. When fully feed they crawl away to a hiding place to digest the meal. When hungry, bed bugs again search for a host and the process starts all over again.
The bugs locate the host by detecting warmth and carbon dioxide. Once located the bed bugs starts to feed by injecting the host with saliva that is a mild aesthetic making the bite itself painless, then feeding, sucking blood, commences. Reactions to the bites can take as long as 5 days before wound appear these are often all over the body. Some people have an allergic reaction to the bites which can result in to a nasty welt which is usually followed by a desire to scratch the bite sites.
