What's the temperature at room temperature? Can't mosquitoes survive?

Mosquitoes can't live at room temperature below 20 degrees.

Mosquitoes are very sensitive to temperature. Only when the temperature is above 20℃ will it breed and lay eggs, that is, blood sucking.

In fact, mosquitoes suck blood not to "eat", but to breed.

Mosquitoes actually eat tree juice and nectar every day, from which they absorb sugar to maintain their metabolism.

Then why can't mosquitoes suck blood like bees and butterflies that only eat nectar from tree juice? "Because female mosquitoes need to ingest protein in the blood to promote ovarian development and maturity, they can lay eggs."

As for the methods of killing mosquitoes and repelling mosquitoes, besides physical isolation with mosquito nets, electronic mosquito killer, mosquito repellent incense and mosquito repellent spray are all commonly used methods.
