Mosquitoes bite anyone, but they still have their favorites; we tell you which ones.
One of the most unpleasant things that can happen in everyday life and that no one can get rid of is mosquitoes.
We have to accept that even if it happens little, it is enough for us to want to rip off the piece of skin where it is.
But why do they sting? Why do some people do worse than others in this matter? To begin with, you have to understand that mosquitoes bite instinctively because this is the way they feed so don’t take it personally, they do it simply because it is born of the heart.
Scourge of hot summers, they rot our evenings and nights by turning around for hours in order to drink our blood. Not content to buzz near our ears and prevent us from sleeping, the mosquitoes end up irretrievably biting us leaving on our skin itchy blisters. But by the way, why are they stinging us?
Only the female mosquitoes bite
The media Brut has made a short video that explains why mosquitoes love to replenish our blood so much. First information distilled by the video: only the female of the mosquito bites humans. And for one reason: our blood is essential to it to reproduce.
Feeding mainly on nectar and the sweet juice of ripe fruit to meet their energy needs, adult female mosquitoes need proteins in mammalian blood to allow their eggs to mature before laying eggs.
Most often, mosquitoes bite at night, especially at dawn or dusk. If he is not disturbed, it only takes him two to three seconds to take ours without before taking off again. Interestingly, unlike most other insects, the mosquito mostly uses its wings to take off, not its legs.
This allows it to be as quiet as possible and not end up crushed against a wall. During the bite, the female of the mosquito injects anticoagulant saliva which, in humans, causes an inflammatory allergic reaction more or less important depending on the individual: it is the formation of the famous “buttons” that itch.
But let us rejoice: we are far from being the main victims of mosquitoes. More than half of the species feed exclusively on the blood of birds, followed by rodents and large mammals, reptiles and batrachians.
Mosquitoes have their preferences
And if you still find that you get stung more than your friends or family members, there’s probably an explanation.
Indeed, several studies have found that mosquitoes have their preferences for human blood. For example, research dating back to 2004 showed that people in blood groups A and O were more likely to be bitten by mosquitoes than those in Group B.
According to the researchers, 85% of humans secrete a chemical signal through their skin that informs the mosquito about the type of blood type, so they refer to it to choose their prey.
Another element that can play against you is the presence of carbon dioxide in your breath, which can attract mosquitoes from 50 meters away. This explains why children, who exhale less CO2 than an adult, are less stung. But also why pregnant women particularly attract them: they exhale on average 20% more carbon dioxide and have a higher body temperature.
Mosquitoes also love the blood of athletes: the presence of lactic acid, uric acid, and ammonia in their sweat attracts them like a magnet.
These flying insects are able to identify the place where a person is up to 50 meters away; their smell is able to detect when there is more carbon dioxide in the environment than normal and that’s why when you have a meeting, the first to arrive are them, even if you haven’t invited them.
However, though there is virtually no way to get rid of them, there are certain factors that will make one of these small predators identify you and come directly to attack you probably without you noticing. We tell you what they are so that, as far as possible, you avoid them:
They seem to have nothing to do with it, but it has been shown that people who wear dark clothing are more likely to receive the picket of a mosquito, even though it was previously believed that it was the bright colors that called them.
Alcohol in the blood
On the other hand, it has been seen that mosquitoes like people who drink alcohol and obviously the more, for the better. This has its explanation in the change that your smell suffers when you consume alcoholic beverages because all of that comes out through the sweat glands and they can identify you immediately.
Avoid stagnant water
The tiger mosquito can transmit tropical diseases such as dengue and chikungunya fever, so experts advise fighting any occurrences – which is a matter for the federal states. However, experts say the risk of contracting the disease is low. So far, no mosquito has been discovered in this country that carried such a pathogen. “There is only a danger when an infected returnee is stung and the mosquito transmits the pathogen to another person,” says Susanne Glasmacher of the Robert Koch Institute in Berlin.
Even without infection, mosquito bites are stressful. In order to push the animals back, breeding opportunities should be taken away from them.
Finally, be aware that what you wear can also make it easier for you to be spotted by mosquitoes. According to Professor Jonathan Day, a physician at the University of Florida, these insects would use their eyesight to spot their future prey and would be particularly susceptible to black, navy blue, and red.
