Bedbugs or bed bugs are small parasitic insects and live by feeding exclusively on the blood of warm-blooded animals. The name "bedbug" is derived from the insect's preferred habitat of houses and especially beds or other areas where people sleep. Bedbugs, though not strictly nocturnal, are mainly active at night and are capable of feeding unnoticed on their hosts.
It is the most irritating insect I’ve ever known (aside from cockroach). I hate it because recently I was not able to sleep well because this stupid bug keeps on biting my skin that creates a number of rashes in my skin. Also I need to sleep on the floor for me to avoid this creepy creature.
