Principle: Mosquito coils with a long history are the earliest insecticides used, and similar mosquito repellent sticks made of traditional Chinese medicine appeared thousands of years ago in the Southern Song Dynasty. Mosquito coils use high-temperature combustion to slowly release insecticides into the air, and the mosquito repellent effect is greater than the mosquito killing effect.
Disadvantages: There is also a study that a substance will be produced when ignited and oxidized by mosquito coils synthesized with wood chips, rice bran, etc., which may lead to cancer.
Tip: Experts recommend that mosquito coils are best used outdoors, such as around your home, at your doorstep, or in areas with good ventilation. In the evening, before dark, the mosquito coil has the best effect on mosquito repellent.

Here's how mosquitoes bite:
Only female mosquitoes bite, but they don't bite every time they encounter a person. It bites and sucks blood, mainly because it needs human blood to reproduce the next generation, and uses the blood it sucks to lay hundreds or thousands of eggs. The mosquito relies on its tentacles and sensors on its three pairs of legs.
When a person is asleep, he exhales carbon dioxide, and the mosquito slowly follows the smell, buzzing over his head, while using its proximity sensor to measure the humidity, temperature, and composition of the sweat in order to determine whether it is a suitable target.
Mosquitoes
Mosquito (scientific name: culicidae), a mosquito of the family Mosquitoidae, is a small flying insect with stinging and sucking mouthparts. Multicellular organisms with elongated bodies and feet, usually females feed on blood, while males feed on the sap of plants, preferring to inhabit hidden, dark and poorly ventilated areas, found on all continents except Antarctica.
The first major category is Anopheles mosquitoes, the characteristics of Anopheles mosquito adults are that most of the wings are spotted, the body is mostly gray, the body is staying, and the finger surface of the stay is at a certain angle, and it is mostly active at night; The larvae of Anopheles sinensis mosquito breed in large stagnant water, such as rice paddy fields, swamps, reed ponds, slow-flowing ditches, etc.
The second major category is Culex mosquitoes, the characteristics of Culex mosquito adults are that their wings are mostly spotless, their body color is brownish-yellow, and when they stay, they tend to maintain a balanced state with the staying surface, and they are in a parallel state, and their activities are mostly at night; A genus of the subfamily Culae mosquitoes. Commonly known as Culex mosquitoes. It is widely distributed all over the world and is the second largest genus of the mosquito family, with more than 800 species and subspecies known.

Male mosquitoes do not suck blood and feed exclusively on the nectar of plants and the sap in fruits, stems, and leaves. Once the female mosquito is mated, only by sucking blood can the ovaries develop and reproduce. Mosquitoes bite day and night, depending on their species.
Generally, Aedes mosquitoes mostly suck blood during the day, and Anopheles mosquitoes and Culex mosquitoes mostly suck blood at night. <

Mosquitoes have the following characteristics:
1 Breeding habits:
Mosquitoes breed in water, and different types of mosquitoes breed in different water quality and types of stagnant water.
2 Vampiric Habits:
Only females suck blood, males do not. Female mosquitoes must suck blood from their ovaries in order to develop and reproduce. Female mosquitoes mostly begin to suck blood 2-3 days after emergence, and various factors such as temperature, humidity, and light can affect the blood-sucking activities of mosquitoes, and they begin to suck blood when the temperature is above 10.
3.Habitat Habits:
Generally speaking, mosquitoes like to inhabit in hidden, dark and poorly ventilated places, such as under the bed, behind the cabinet, behind the door, in the wall cracks, livestock houses, basements, etc., and the outside of the room is mostly in the grass, caves, cellars, bridge holes, stone cracks, etc.
4.Winter. In general, mosquitoes begin to appear in April every year and reach their peak activity in mid to late August.
In autumn, when the climate gets cold and the temperature drops below 10, mosquitoes will stop breeding and die in large numbers, and very few mosquitoes will survive, and they will hide in places where they can take shelter from the wind and cold, such as in the cracks of walls, such as in warmer and more hidden places indoors, such as behind a wardrobe. However, they will avoid hotter places, such as heating, etc.

After research, many data show that the most fierce mosquito bite in summer is the female mosquito during pregnancy, at this time the female mosquito will avoid the male mosquito, using this feature, the design of electronic frequency conversion line, so that the mosquito repellent produces ultrasonic waves similar to the male mosquito flapping wings, to achieve the purpose of driving away the female mosquito. The mosquito repellent emits a rhythmic "dripping" sound, which uses high-tech circuitry to simulate the sound of male mosquitoes and dragonflies fluttering their wings, based on these basic principles of biology and bionics. At the same time, these two sounds are combined into a special ultrasound wave that allows mosquitoes to flee when they hear the sound.
Because the frequency of ultrasound is constantly changing in a large range, it can adapt to various mosquitoes and insects, and will not make them "adaptable" and "immune", and there is no harm to the human body.
Mosquito repellent electronic appliance made according to the principle of bionic electronics. There are usually ultrasonic electronic mosquito repellent devices that mimic the ultrasonic signals emitted by male mosquitoes to repel female mosquitoes; Bat-type electronic mosquito repellent that mimics the radio signals emitted by bats to repel mosquitoes; A photoattractant electronic mosquito repellent that uses the phototaxis of mosquitoes to lure them to a high-voltage metal wire located around a certain wavelength ultraviolet light source to kill mosquitoes; Using the phototaxis of mosquitoes, the UV lamp emits a specific wavelength light to attract mosquitoes to the vicinity of the lamp, and then uses the adhesive tape or sticky plate that blocks the mosquito's flight path to stick the mosquito to the sticky trap electronic mosquito repellent.
Generally, when mosquitoes are forced to escape, the sound waves used to repel mosquitoes are above 23kHz, which is much higher than the hearing range of the human ear, so the human ear cannot hear it, and it will not affect the normal work, so as to achieve the effect of repelling insects and mosquitoes.

A plug-in mosquito killer is called an ultrasonic mosquito repellent. It uses a triple ultrasonic mosquito repellent mode, dragonfly flapping wings and two male mosquito flapping wings to repel mosquitoes, without any chemical raw materials or dangerous devices, and will not cause adverse effects.
It has been scientifically proven that only female mosquitoes bite humans and animals during the breeding season to feed their eggs, however, female mosquitoes hate contact with male mosquitoes during this time. Based on this principle, this product produces ultrasonic waves that mimic the emitted by male mosquitoes, so as to achieve the purpose of repelling biting mosquitoes. Dragonflies are natural enemies of mosquitoes, and this product imitates the sound of dragonflies flapping their wings, so as to achieve the purpose of repelling all kinds of mosquitoes.
Precautions for using electric heat repellents:
1) Disconnect the aluminum foil of the tablet when using, take out the tablet and put it on the heating plate of the electric heater, let the tablet be in complete contact with the heat transfer plate and then connect the power supply, if there is unevenness, you can use hand tablets to make it consistent with the heat transfer plate.
2 sea tablets can be used continuously for 8 hours, after the tablets are white, a new piece should be discarded, if it is not used up at one time, the tablets should be re-put into the aluminum foil or closed bottle for preservation, and then used at night.
3) In order to achieve the best effect of mosquito control, when the tablets are heated by electricity, the doors and windows should be closed to minimize the indoor air flow, and the windows should be opened after about 30 minutes. To prevent outdoor mosquitoes from entering the room, doors and windows should be fitted with nets.

Attract a mosquito to an electric mosquito and electrocute it.
-
The principle adopts the triple ultrasonic mosquito repellent mode, after all, mosquitoes rely on sound waves to find their way.
-
By electric shock, electrocution of mosquitoes, in a more brutal way.
-
Attract mosquitoes to the grid and be electrocuted.
-
Attract with lights, and then electrocute with electricity.

In general, mosquitoes prefer sunny, damp and watery places, so most of them like to come out at night, but different mosquito species have different habits. Some mosquitoes like to inhabit, mostly in the mosquito net, under the bed, in the corner of the house, behind the door and other places There are more than 2,000 kinds of mosquitoes in the world, and more than 300 species have been found in China. Culex mosquitoes, Anopheles mosquitoes, and Aedes mosquitoes are the three main blood-sucking mosquitoes and the most common mosquitoes. >>>More
Mosquitoes are poisonous and will hurt when bitten. Bites should be treated with disinfectant.
Mosquitoes generally start in May and reach their peak in mid to late August. When the temperature drops below 10 degrees Celsius, the remaining mosquitoes will stop breeding and enter hibernation without food. Many people think that mosquitoes only come in the summer and that they will die out in the fall. >>>More
