Sihaiwang: in summer, in addition to the heat, there are also a lot of mosquitoes. You can hear the hum in your ears when you want to go to sleep in the dead of night. It's too noisy to sleep. I wish I could shoot them all to death. So why don't mosquitoes come out during the day? How high is the floor to avoid mosquitoes? Let's learn about it with Xiaobian!
How many floors do you live without mosquitoes
Generally, there will be mosquitoes on all floors, but there will be more mosquitoes on the 1st to 5th floors, and there will be less mosquitoes on the higher floors. Mosquitoes are usually under 10 meters. That is to say, most of the mosquitoes are active on the 1st to 5th floors. From the 6th floor, there will be fewer mosquitoes, but there will be more or less. Some mosquitoes with abundant physical strength can also fly to the 10th floor, which is the limit height that mosquitoes can fly naturally. Moreover, most of the mosquitoes that can fly to the 10th floor are male mosquitoes, which do not directly bite people.
Why there are mosquitoes at the top
In theory, the highest flying altitude of mosquitoes is about 15 meters, which is about 5 to 6 floors. Sometimes there are mosquitoes in more than 20 floors. What's the matter?
In fact, the reality is not as mentioned above. Mosquitoes first fly from the ground to the 6th floor, and then lay their eggs on the 6th floor. Then the take-off point of the second generation of mosquitoes starts from the 6th floor. If the second generation of mosquitoes lay their eggs on the 12th floor, the take-off height of the third generation of mosquitoes will become the 12th floor. So even buildings with 20 or 30 floors will not be completely free of mosquitoes, but the number of mosquitoes will be less.
Therefore, the height of the floor has nothing to do with the emergence of mosquitoes, so we don't need to choose a higher-level house to avoid mosquitoes in summer. Of course, we should try not to choose a lower floor. After all, there are a lot of mosquitoes here.
How to avoid mosquito breeding
Clean up, clean up the source. The development of mosquito needs four stages: egg, larva, pupa and adult. Mosquitoes will lay their eggs in the water, only need a little water to reproduce, so we need to control the source, often clean up the water, so that mosquitoes can be killed in the cradle.
Who is easy to recruit mosquitoes? 1. People with high temperature and more carbon dioxide
Mosquitoes are very sensitive to temperature. Therefore, people with a large body will release more carbon dioxide, especially after exercise and wheezing, they are more likely to be bitten by mosquitoes. The perspiration person body heats quickly, can let the mosquito feel immediately.
2. A man of taste
The chemical composition on the skin of everyone is not the same. Compared with people who sweat as usual, lactic acid is discharged from the skin surface, which is easier to attract mosquitoes.
3. A person who has made up or sprayed glue
Stearic acid in cosmetics has certain attraction to mosquitoes.
4. People in dark clothes
Mosquitoes have the habit of darkening. Black is their favorite color, followed by blue, red and green.
Why don't mosquitoes come out during the day
This is determined by the living habits of animals. It is safer to hunt and protect yourself at night. Mosquitoes have poor vision. It doesn't matter whether they are light or not. Most mosquitoes forage in the evening or at dawn, because the dry heat in the summer day will dehydrate them to death, so they usually stay in the hidden and humid places during the day, and only come out in the evening and at night. The mosquitoes that move at dawn or in the evening are usually Culex and Anopheles.
What mosquito will bite in the daytime
Not all mosquitoes come out at night to bite, and some come out during the day. There are many kinds of mosquitoes, and their activities are not the same. Some species like to move in the daytime, high temperature and low humidity. They move frequently from morning to afternoon. They stop after dark. Aedes is the mosquito that bites people in the daytime. We should do a good job of mosquito control in both day and night.
