In the Jurassic period, 1.7 billion years ago, the ancestor of mosquitoes evolved. The earliest fossil evidence is found in chalk.
among the rock formations of the period. The first area where mosquitoes evolved was in present-day South America, then gradually migrated north to the ancient continent of Laoa, and then moved south again to the tropics. The ancestors of mosquitoes were about three times the size of the extant species and were closely related to the family Chaoboridae.

The peak time of mosquito infestation is in the summer evening, especially if you live in a mountainous village, and at night mosquitoes will fly outside from shady places to find targets to suck blood. Mosquitoes are afraid of cold and heat, and things will smell after a long time in summer, these smells are the easiest to attract mosquitoes, and careful people will find that there are many mosquitoes hidden next to the garbage can every summer, and their living environment is dirty, and they will spread the virus while sucking blood.
How can I prevent mosquito bites?
Mosquitoes will exist in both urban and rural areas, in order to prevent mosquito bites, you can apply mosquito repellent on your body, there are many types of mosquito repellent on the market, and it is not that the more expensive the better. Choose according to your own situation, light mosquito coils when sleeping or insert mosquito coils in the house.
When working in the farmland, mosquito coils in an open environment are basically ineffective, and you can apply toilet water to yourself.
DEET, etc., try to wear long clothes and trousers. Pay attention to the hygiene of the living environment, often clean the dark and damp places, and spray insecticidal aerosols in mosquito-infested places so that mosquitoes have nothing to hide.

Sometimes you can see mosquitoes biting on your arms, and the correct thing to do is to repel them, not slap them to death. After being bitten, there will be redness, swelling and itching locally.
You can apply an anti-itch ointment to the wound and never scratch it with your fingernails. Most mosquitoes can resist their toxicity through autoimmunity, but some children will have a serious reaction after being bitten and should be sent to the hospital in time to save them.
What should I pay attention to when using mosquito coils to repel mosquitoes?
Mosquito coils ignite when ignited.
It can reach 800, so keep the mosquito coil in the open without flammable items.
Some time ago, a funny lady actually lit more than a dozen plates of mosquito coils and put them in cardboard boxes, and then went to work by herself. Sure enough, a fire broke out in the house soon after, but fortunately, the community staff found it in time, otherwise it would have caused disaster to other residents. Now the mosquito coil repellent effect is very good, you don't have to order too much, otherwise the air quality in the house.
It's not good.

Mosquitoes generally start in May and reach their peak in mid-to-late August. In autumn, when the climate gets cold and the temperature drops below 10 degrees Celsius, it stops breeding, dies in large numbers, and goes into hibernation without food until it wakes up the following spring.
My favorite temperature is around 30 degrees Celsius, and I can't stand it if it's too high. Their living and breeding environment must have water, so mosquitoes often breed in places such as ground water, smelly ditches, sewers, etc., and mosquitoes choose objects based on their smell.
The activity of mosquitoes mainly refers to the behavior of seeking and sucking blood from the host, and its activity ability is related to temperature, humidity, light and wind. Most mosquito species are active in the early morning, dusk or night, and Aedes mosquitoes are mostly active during the day.
Growing up:
Depending on the species, mosquito eggs may be laid on the surface, near the water, or in three different locations: Anopheles mosquitoes and house mosquitoes on the water surface, and Aedes mosquitoes at the water's edge. Anopheles mosquitoes and house mosquitoes hatch in about two days, while Aedes mosquitoes hatch in three to five days.
Female mosquitoes lay eggs in stagnant water. Mosquito eggs are small, less than 1 mm long. Anopheles eggs are scaphoid in shape, with buoys on both sides, which float on the surface of the water after being produced.
The eggs of Culex mosquitoes are conical in shape, without buoys, and after being produced, they stick together to form a raft of eggs. Aedes mosquito eggs are generally olive-shaped, have no buoys, and sink to the bottom of the water individually after being produced. Mosquito eggs must be in water to hatch, and in the summer the larvae usually hatch after 2-3 days.

November-March. Mosquitoes begin to emerge in April each year and reach their peak in mid-to-late August. In autumn, when the climate gets colder and the temperature drops below 10, mosquitoes stop breeding and die in large numbers, with very few mosquitoes surviving.
Mosquitoes are sensitive to strong air currents and have a low survival rate at low temperatures.
Mosquito eradication method:
1. Eliminate the living environment of mosquitoes.
Some have poor living environment, there is a lot of stagnant water around, and they need to spray frequently, which is not only difficult to kill mosquitoes, but also costs a lot of money.
Solution: Don't keep garbage indoors and don't leave stagnant water.
2. Soapy water.
Close the doors and windows, place a basin in front of the window, add some water mixed with laundry detergent, and the next day, there will be some dead mosquitoes in the basin. With this method used every day, it is almost impossible to spray insecticide to kill mosquitoes, and there will be fewer and fewer mosquitoes.

1. Generally, mosquitoes begin to appear in April every year and reach the peak of activity in mid to late August.
2. When the climate becomes cold in autumn and the temperature drops below 10, mosquitoes will stop reproducing and die in large numbers, and very few mosquitoes will survive, and they can shelter from the wind and cold in the cracks of the wall, such as hiding in warmer and more hidden places indoors, such as behind the wardrobe. However, they will avoid hotter places, such as heating, etc. This can not only avoid the harsh winter, but also reduce the rate of metabolism and avoid starvation.
It's kind of like hibernation.
