Bedbug

They drink, and drink, and drink – up to three times their own body weight. No wonder, they are called the ultimate binge drinkers. At times, they are too bloated to return to their homes. Their stealthy lifestyle of drinking, and their habit of helping themselves uninvited stirs the strongest psychological fear amongst people. Evolved some 100,000 years ago, the drinking habit of bedbugs has sustained them as a species at the cost of humans, who continue to shudder at the mere mention of these tiny bloodsuckers. Their influence on our lives has been unprecedented, pretty much every other bug, including the stomach bug, the computer bug, and the electronic bug carries that name tag.
