Now that the southern region is already in a state of semi-summer, the maximum temperature in Guangzhou in the coming week has reached 33 degrees, and it is difficult to sleep without air conditioning at night.
As the temperature rises, it's not just what you wear, what you get in, what you do, but also how you sleep. Because after the temperature rises, mosquitoes also begin to increase.
The number of mosquitoes varies greatly depending on the season, and the main factors affecting the seasonal growth of mosquitoes are temperature, rainfall and breeding habits of mosquitoes, so the summer temperature is high, humidity is large, and the amount of rainfall is large, which is suitable for mosquito breeding and mosquito density. Winter temperatures are too low, not only can not develop and reproduce, but also a large number of deaths, so the density is greatly reduced. Although some mosquitoes may not die, they are already in a state of sleep without eating or moving.
In order to deal with mosquitoes, we have accumulated a lot of experience, and physical and chemical methods of mosquito repellent have emerged in an endless stream.
Physical mosquito repellent: mosquito nets, screens, electric mosquitoes, etc
Chemical mosquito repellent: mosquito coil, electric mosquito repellent, etc
Now one way to compare fire is: anti-mosquito lights
What is an anti-mosquito lamp? The anti-mosquito lamp is a simple and practical mechanical device that traps mosquitoes by releasing beam chemicals and then catching mosquitoes through a negative pressure device according to the living habits of mosquitoes.
The principle of the anti-mosquito lamp is: the use of mosquitoes to light, moving with the air flow, sensitive to temperature, like to gather, especially the use of mosquitoes chasing carbon dioxide breath and foraging pheromones and habits to develop. Generally divided into: electronic anti-mosquito lamp, stick-catching anti-mosquito lamp, negative pressure air flow suction mosquito lamp three kinds.
The following takes a brand of negative pressure airflow suction mosquito lamp as an example, and talk about why the mosquito lamp is less attractive to mosquitoes than yourself.
1. Although mosquitoes have a certain degree of phototropism, different mosquitoes have different sensitivities to different wavelengths of light, so it is difficult to attract all types of mosquitoes with mosquito repellent lamps with only the same wavelength of light, which makes the anti-mosquito effect of mosquito lamps limited.
It is possible to attract non-blood-sucking mosquitoes
The mosquito belongs to the chironomidae of the family Chironomidae, commonly known as non-biting midges, which translates to non-biting midges.
2, mosquitoes are attracted by the infrared rays generated by the heat of the lamp, rather than by ultraviolet rays. If there are people indoors, mosquitoes will be attracted to people, and ultraviolet mosquito lamps are wood with attraction effects.
The following figure is the infrared heat map of people and anti-mosquito lamps, when people and anti-mosquito lamps are together, the heat of the anti-mosquito lamp is really a small witch.
3. Why can mosquitoes attract mosquitoes?
Now many anti-mosquito lamps in addition to the use of light attraction, but also add "attractants" to attract real mosquitoes over. Then use negative pressure to attract mosquitoes to the inside of the mosquito lamp, and kill mosquitoes by "air drying".
4, for mosquitoes, anti-mosquito lamp is only a bionic principle, human body temperature, smell is more attractive, if you have purchased a fan of anti-mosquito lamp, it is recommended to place in the living room, toilet, kitchen and other places far away from people.
