Why Mosquitoes fond of you ,not others
Research reveals why some people are constantly under attack from the bloodsucking insects, while others walk free.
For those unfortunate enough to feature highly on the mosquito hit list, summer nights are synonymous with mosquito bites.
Yet others hardly ever get bitten. So how do the bloodthirsty insects select their victims?
Scientists rubbed dishes against their stomachs. The mosquito season gives rise to countless speculations about possible solutions to
the age-old mystery of mosquito preferences.
The insects’ tastes may seem arbitrary. However, research reveals that when mosquitoes make their choice between potential victims,
it all comes down to scent:Mosquitoes are attached by carbon dioxide and heat, which everyone gives off. But mosquitoes are also attracted
by certain scents.Karl-Martin VAGN Jensen. According to Jensen, it has not yet been established exactly what the scents in question are.
But research does indicate that some scents are more attractive to mosquitoes than others.
“All the lab employees rubbed dishes against their stomachs. In that way, their scents were deposited on the dishes, which were then put
in an enclosure full of mosquitoes,”
“The mosquitoes repeated landed on some of the dishes, but didn’t go anywhere near the others. “
Vitamin B does not scare off mosquitoes. The experiment is one of several to squash one of the many myths concerning the unfortunate art of
mosquito attraction.While some believe that it is in fact sour blood that keeps the insects at bay, or that the mosquitoes
can detect blood disease, others are
convinced that vitamin B provides protection against mosquitoes.However, there is no indication that any of these theories are correct,
says Jensen: “There is no truth to that. The theory about vitamin B has been tested very, very thoroughly, and it doesn’t hold.”
“As far as I know, there is no scientific proof that eating garlic works. But there may be something to the theory that it’s possible to mask
your scent with garlic,” he says.
The only reliable method of protection against mosquitoes is to use one of the effective repellents that are sold over the counter. Mosquito
repellent contains some smells that confuse the mosquitoes. The first thing a mosquito does when looking for prey is to see if there are any
animals or people in the vicinity.
“When the mosquito comes closer, it uses smell, heat and carbon dioxide to decide whether to bite. But if it is confused by a repellent, it will
never get that far,” says Jensen. However, even repellents do not provide complete protection against the persistent insects.
“Repellents reduce the number of bites by as much as 70 percent. That’s all well and good, but you’ll still get bitten once in a while.”
