Why are there mosquitoes when I live on the 22nd floor?

There is standing water somewhere in the house or you go up with the elevator.

There are still mosquitoes on the 28th floor for the following reasons:

1. There is an environment for mosquitoes to live in the home, that is, the indoor warmth is very good, many families are obviously late autumn, but there is still a pseudo-autumn climate, and even some families have turned on the heating or air conditioning in advance, so mosquitoes can also adapt to it.

2. There is an area for mosquitoes to breed at home, and the larvae of mosquitoes are in need of an aquatic environment, so there are two places where there is an aquatic environment indoors, one is the water tank of the bathroom, many families have a second bedroom, and the bathroom is equipped with a bathroom, and the toilet tank has also become an incubation base.

The second is plant pot picking, some aquatic plants, such as lotus, are also one of the main environments for mosquitoes to lay eggs, and the solution is also very simple, just raise fish in pots.

Protect against mosquito bites.

1. Install screens and mosquito nets in summer. Whether it is mosquito repellent water or smoked vinegar, it is not as safe and reliable as physical mosquito repellent.

2. You can put some orange peel, star anise, fennel, etc. in the room to repel mosquitoes, because mosquitoes don't like the special smell emitted by these things.

3. The pots and pots, floor drains, sewers, flower pots and other places that are prone to water accumulation in the home should be cleaned up in time, and the lid should be closed, and the water should be changed frequently.

4. If there are still some mosquitoes entering the screen window and mosquito net, you can use some mosquito repellent supplies, such as mosquito coils and mosquito repellent liquid.

Why: The secret to allowing mosquitoes to climb the heights of their flight** is the elevator in a high-rise residence. In fact, it is easy to breed mosquitoes in places with stagnant water such as basement

Mosquito repellent method:

1. Mosquito coils. After the mosquito coil is lit, the pyrethroid in the mosquito coil is evaporated with the smoke and dispersed in the indoor air, paralyzing the mosquito's nerves, causing it to either fall to the ground and die, or scatter and flee. Mosquito coils are best used outdoors, such as around the home, at the door, or in a well-ventilated area. In the evening, light mosquito coils before dark for the best mosquito repellent effect.

2. Spray insecticides.

Its main chemical ingredient is an insecticide called profenethrin. Spraying insecticides on stairwells, under sinks, gutters, toilets, cupboards, and under tables can effectively kill mosquitoes. You don't need too many insecticides, too much is not only wasteful, but also pollutes the environment, and the key is to know the time, place and amount of mosquito control.

3. Anti-mosquito solution.

Also known as mosquito repellent. The main ingredient of insect repellent is DEET. Applying a qualified insect repellent can stop mosquito bites within 6-8 hours. The principle is that the drug directly acts on the tactile organs and chemoreceptors of mosquitoes to achieve the purpose of repelling mosquitoes.

4. Mosquito repellent toilet water.

It contains bionic repellent raw materials, which can make mosquitoes have the illusion of biting and lose their desire to bite. The time limit can be up to 5 hours each time. Some mosquito repellent lotions also contain precious Chinese herbal ingredients, which have the functions of cooling, removing heat heat, and avoiding heat, which can be described as a multi-purpose.

The room and the spraying agent should match, that is, the amount of medicine used; Mosquitoes are on the 28th floor with people and corridors or elevators, and it should be noted that the effect of spraying some pesticides at the door of the unit should be doubled. We hope you will be able to solve your troubles.

There will also be mosquitoes on the 23rd floor, but there are many fewer mosquitoes on the lower floors. Although theoretically mosquitoes can't fly very high, but mosquitoes parasitize between people's lives, and will use elevators and stairs to rise step by step, and small insects are constantly evolving, and they are also adapting to human society.

Mosquitoes belong to near-Earth organisms, and their flight altitude is limited, generally more than 10 or 20 meters, so they generally mainly operate in the area below 6 floors, and there are relatively few mosquitoes that can fly to high floors.

Mosquito hazards

The main hazard of mosquitoes is to transmit diseases. According to research, there are more than 80 diseases transmitted by mosquitoes. No animal on earth is more harmful to humans than mosquitoes.

Malaria is a disease transmitted by the Anopheles mosquito. Malaria is also known as miasma. According to a 1935 survey by the Department of Health, 50 per cent of residents in areas where miasma was prevalent had malaria parasites in their blood, and 72 per cent had falciparum malaria.

In 1936, about 20,000 people died of malaria in Gao County, Jiangsu, and in 1876, when the Panama Canal was dug, countless workers died due to yellow fever and malaria, so that work had to be stopped in 1889. Later, the problem of mosquitoes was solved by entomologists and the canal project was continued. The report of the Far Eastern Society of Tropical Diseases in 1930 stated:

About 50 people die each year from the mouth of the tiger and 50,000 people die from malaria.

It's an interesting question, but I've had a similar experience in practice, when a mosquito is driven out of a high-rise building (which is often difficult to repel), it immediately stays next to the window, and when the window doesn't close in time, it invades again. If it fails to break in, it will try to fly away, but with the updrafts of high-rise buildings, it can only move with the currents! I believe everyone understands this urban airflow!

Mosquitoes can do elevators, I've seen it 2 times.

Yes, flies and mosquitoes are all from the elevator up to the headlines.

Mosquito one-time flight altitude.

Generally between 10-15 meters, let it rest for a while to fly, at most 30 meters, and can have such good physical strength, basically males, do not bite.

The higher the floors, the higher the height of the mosquitoes, because the breeding space of the mosquitoes is also slowly climbing. For example, if the mosquito flies from the ground to the fifth floor and lays eggs on the fifth floor, then the starting point of the second generation of mosquitoes is from the fifth floor, and the second generation of mosquitoes can fly near the 13th floor and lay eggs from the 13th floor, so the height at which the third generation of mosquitoes can fly will also increase.

So in fact, even a 20-story house is not necessarily 100% free of mosquitoes, but the probability of mosquitoes will be relatively small.

And the appearance of mosquitoes, and the surrounding environment of the house has a very close relationship, if there are swimming pools, green belts, etc. around the floor, then mosquito breeding will naturally be more.

There is no inevitable relationship between the height of the floor and the appearance of mosquitoes. To prevent mosquitoes, first of all, do a good job of household hygiene, balcony flower pots should be cleaned up regularly, reduce stagnant water breeding mosquitoes, it is best to install screen windows and so on.
