Where did they go? Unlike birds, mosquitoes don't fly south in groups in winter. What a terrible idea! ) They can't fly far. For male mosquitoes and female mosquitoes, there are different answers to the question "Where did the mosquitoes go in winter?" The male mosquitoes died directly, but not because of the cold.

"They can hibernate in cold and water-free conditions for up to six months," said Jayme Bella, founder and CEO of Greenerways Organic, a pest control company. "They only wake up when it is warm and moist." When the environment gets warmer again, the female mosquitoes wake up and it's time to start collecting blood. They are ready to lay eggs and need as much blood as possible to provide nutrition for egg development. So yes, only female mosquitoes will bite you.
