Bed bugs bites, although not dangerous, can cause itching and swelling of the skin. The best way to prevent bed bug bites is to identify the location of the infestation and destroy it. This may take time during which bed bugs continue to bite. Bed bugs normally leave the body after they have finished sucking human blood.
Bed bugs (Cimex lectularius) are small, flat, parasitic insects that feed solely on the blood of people and animals while they sleep. Bed bugs are reddish-brown in color, wingless, range from 1mm to 7mm (roughly the size of Lincoln's head on a penny), and can live several months without a blood
Their front claws actually need to be set in a certain way before they begin feeding, which is hard enough to do without hair getting in the way. When bed bugs come to feed, they would much rather do so on bare skin. If you do find bugs crawling around your skin or hair, take a hot shower with liberal use of soaps and shampoos.
They can only crawl for locomotion, so moving from the floor to the bed requires them to climb up a leg of the bed, or to scale belongings or furniture you've placed nearby. This can work to your advantage if you're battling bedbugs, as you can create barriers to keep them from climbing onto your bed.
These mites dig tunnels under your skin and lay eggs in them. You can get them if you have close contact or sleep in the same bed with someone who has them. They're too small to see, though. They prefer the skin between fingers, arm and leg folds, the penis, breasts, and shoulder blades.
Bed bugs do not live in your skin. They live in cracks on your headboard and also under your mattress. They come out at night to feed on your skin.
