蚊子 (wén zi): 모기.

Summer has arrived, and at night when sleeping there are especially many mosquitoes; the buzzing sound is so noisy that I can't fall asleep.

When we went on a picnic, a mosquito bit my arm, and soon a red bump appeared and it was very itchy.

To prevent mosquitoes from spreading diseases, the government advises residents to eliminate standing water and use mosquito nets and repellent.

I lit a mosquito coil in the room, hoping to drive the mosquitoes away, but it seemed to have no effect.

There are far more mosquitoes in tropical regions than in the north; when traveling there, you must bring mosquito repellent.
