A mass extinction of mosquitoes would result in the disappearance of about 3,500 species, which is just the number of mosquito populations currently recognized on the planet.

Mosquitoes have existed on Earth for hundreds of millions of years and have become an important part of the food chain.

Facts have proved that even if scientists can find a way to eliminate mosquitoes completely, it will cause serious ecological problems.

In the Arctic tundra, for example, there are several species of mosquitoes that are abundant as food for migratory birds.

Once these mosquitoes become extinct, the area's bird population could be reduced by more than half.

Mosquito repellent methods: 1. Use mosquito nets or screens to isolate mosquitoes. Mosquito nets can prevent mosquitoes and wind, and can also absorb falling dust, especially suitable for children.

Screens allow fresh air to enter the room while allowing harmful smoke to flow outside.

2. Place a few uncovered boxes of cooling oils and essential oils in the bedroom, or place one or two pots of blooming tuberose, jasmine, Milan, mint or roses, etc. Mosquitoes will avoid them because they cannot tolerate their smell.

3. Install an orange-red light bulb indoors, or cover the light bulb with translucent orange-red cellophane. When the light is turned on, mosquitoes will flee because they are afraid of the orange-red light.

4. Fill an empty wine bottle or cup with sugar water or beer and place it in a dark place. Mosquitoes will burrow into the bottle when they smell the sweet wine, and will be stuck to the sugar water or beer and die.

5. Eating raw garlic and taking vitamin B orally, which are excreted from the body through sweat through physiological metabolism of the human body, will produce a smell that mosquitoes are afraid to approach.
