What Makes Some People So Attractive to the Mosquito?
Is the old wives tale true? Are some people just “sweeter” or naturally more attractive to the flying bloodsuckers than others? What exactly makes people a target for a mosquito bite, and why are others seemingly immune to the pests?
Researchers have determined that it is not a smell or taste that drives a mosquito to bite its victim, but rather behavioral patterns or other signs that prey may be less “defensive.”
In fact, a slower, larger animal that has a low activity level will always be more attractive to a mosquito than a lively small one that is bouncing all over the place. Effort and survival play the biggest role in determining potential targets. If a mosquito thinks it can sneak a couple drops of blood from you, safely, and with a decreased chance of being swatted, it’s going to go for it.
Interestingly enough, ingesting alcohol (beer, mostly) can make you a more attractive target for a mosquito bite. This could be because the alcohol slightly raises your body temperature and reduces your reaction time, but it is probably mostly due to the increased apathy the target may exude when under the influence. According to one research study, mosquitos landed on study participants much more frequently after they began drinking beer:
“Thirteen volunteers (12 men from 20 to 58 years old and a 24-year-old woman) were chosen as test hosts and a 30-year-old man was established as a control. We measured ethanol content in sweat, sweat production, and skin temperature before and after ingestion of 350 ml of beer (ethanol concentration 5.5%) by volunteers and compared them with a control subject. Our study demonstrated that percent mosquito landing on volunteers significantly increased after beer ingestion compared with before ingestion, showing clearly that drinking alcohol stimulates mosquito attraction.”
You can reduce your chances of being bitten by a mosquito using bug repellent, which confuses its senses and makes you more trouble than you are worth.
A mosquito bite is mostly harmless, most often causing a slight irritation at the source of the bite, however the mosquito ...
