The same thing every summer: mosquito alarm! Why some people prefer annoying insects and how you can keep them away from you - these facts will surprise you at the next barbecue evening.

The winter was mild, the spring warm and humid - ideal conditions for mosquitoes, which were able to multiply early and abundantly this year. We get to feel that now during mild summer evenings: with lots of annoying mosquitoes and itchy bites!

Some of us literally attract mosquitoes and are always bitten, while others are almost non-existent for mosquitoes. We'll tell you what this is and what you should pay attention to so that mosquitoes avoid you in the future: Eight facts about mosquitoes that you probably did not know yet.

1. Mosquitoes love dark colors

Do you like to wear dark clothes? Bingo, you are mosquito's best friends! They are more likely to fly to dark areas than light ones. If you want to keep the bugs at a distance, it is better to wear light, loose clothing. This also minimizes the fact that the bloodsuckers actually hit your skin when they sting.


2. Mosquitoes like to spend the winter in apartments

... and could lay eggs there in spring. Therefore: If you see mosquitoes in the colder season, it is best to chase them away before they nest and multiply. This also applies to standing water in the garden: rain barrels, buckets with water and garden ponds are particularly popular breeding grounds.


3. Only the females sting

Mosquitoes feed on sap. However, this is not enough for female mosquitoes of some mosquito species: they need certain proteins from the blood of other living beings for their eggs. That's why they suck blood there - and that's why the females are particularly prickly just before they lay their eggs.


4. Male mosquitoes hum higher than female ones

You have two mosquitos in your bedroom and are wondering which one to pounce on? Take those whose sums sound lower! The stinging females have a slightly lower wing beat frequency than the male. The higher-sounding males disturb our sleep just as much with their annoying hum - but at least it doesn't itch everywhere the next day.


4. Electro music takes away mosquitos' lust for sex and stinging

... more precisely: a song by the US DJ and producer Skrillex. In a study, researchers from Mahidol University in Thailand found out: without music, female mosquitoes quickly pounce on their test victim, a hamster, to suckle blood. They then often mate several times. But if the song by Skrillex is running, it inhibits the females' lust for stinging and sex. They take a lot more time to sting at all and then mate significantly less.

It is unclear whether this can be transferred to our domestic mosquitoes. But maybe we should take the ghetto blaster with us on our next Thailand vacation ...


5. Some people actually prefer mosquitoes to bite them than others

... but contrary to popular belief, this is not due to the fact that popular mosquito victims have particularly "sweet blood". Mosquitoes love it wet - and they react to carbon dioxide, i.e. stale breath, and body exhalations. The body chemistry of some people is more attractive to mosquitoes. Each of us produces different amounts of these substances - depending on our genes, but also on our current metabolism.

The respective blood group, which the mosquitoes recognize via a certain chemical signal on the human skin, also plays a role. Mosquitoes mainly target people with blood group 0, as Japanese scientists found out in 2004 in an experiment with Asian tiger mosquitoes. This is followed by people with blood group B. Mosquitoes don't like people with blood group A the least.


6. Mosquitoes are hardly impressed by light

... but, as I said, are mainly attracted by the human smell. The fact that light attracts insects is especially true for moths. The mosquito is also attracted to light - but it doesn't bite.


7. There is less chance of a sting after a cool shower

Those who jog, meanwhile, produce more lactic acid in their sweat. Because mosquitoes are also sensitive to heat, athletes should expect more attacks during training. Conversely, the risk of a sting after a cool shower is significantly lower.


8. After a bite: spit cools, heat stick works

You have been bitten by a mosquito and itchy? Smearing spit on the sting has a cooling effect, but does not help. Difficult as it is at times, avoid scratching or pressing on the sting. This only increases the itchiness unnecessarily. So-called heat sticks can also provide relief. You heat the sting to 51 degrees Celsius for a brief moment. This destroys the mosquito's protein-containing saliva, which triggers the itching in the bite.


Wrong thought: the 8 greatest animal myths

You have to be very strong now: your friends who claim that they used to push cows at night are lying - because cows can't just be pushed around like that. And these myths are also wrong. more
