Insects that fly into the nose can be treated by blowing the nose, sneezing, rinsing the nasal passages, or suctioning out with a nasal endoscopic suction. 1.

This will not only fail to remove the flying insects but may also cause them to enter deeper into the nasal cavity. The correct way to do it is to inhale deeply and then close your breath, press the nostril without flying insects with your hand and then blow your nose vigorously, the strong airflow can bring the flying insects out of the nose. 2.
