They sneak into the night, and pinch something from you. A minuscule precious drop of liquid red ruby. But how long will it really take them to steal every tiny drop? Are these the fabled vampires that steal into the night?
Mosquitoes have a way of attacking you out of the blue like a sly villain that it is. But the real question is, can they drain our blood to the last drop?
An entomologist at Virginia Tech, Zach Adelman, wrote an email to Tech Insider stating that, "one female tiger mosquito will usually drink about five microliters of blood in a meal. That's roughly the volume of a single dried mustard seed. Now consider the average human has 5.5 liters of blood, or 5.5 million microliters." Another study claims that the regular human at about 145-150 pounds has approximately five liters of blood in their body. A mosquito on average will draw five millionths of a liter of blood. Mathematically, it would take 5/0.000005 = 1,000,000 mosquitos to drain everything from the human body, i.e. the whole 5 liters. Conversely, a loss of over two liters, if untreated with a blood transfusion, will most likely end with death. But odds are you'd die long before all your blood was gone.
There are some factual complications about getting bitten by numerous mosquitos. This is a question of presented skin. The human skin is roughly 2 square meters in size. This would require 100,000 bites per square meter. A square meter has 10,000 square centimeters, so this means that there would be about 10 mosquitos which essentially need to bite you per square centimeter. Quite dubious.
Mosquitoes also bite you based on certain reasons such as your blood type, temperature, clothing colour, alcohol consumption etc.
Try to avoid spending time in places where mosquitoes can feast on you as their all you can eat brunch buffet!
