After a bug flies into the ear, the most direct way to determine if it is still in the ear is through an otoscope. In addition to this, you can also self-perceive whether there is any itching, pain, tinnitus, foreign body sensation, noise, etc. in the ear canal. After the bug has flown into the ear, you can sense whether the bug has flown out based on self-perception. If there is no discomfort in the ear, it is usually assumed that the bug has flown out or the bug has died in the ear canal. If there is still tinnitus, itching or pain in the ear canal, it is possible that the bug is still in the ear canal. Otoscopy can accurately determine whether there are worms or dead worms in the ear canal. If necessary, it is recommended to go to the hospital for an otoscopy, and if there are indeed worms or dead worms, you can remove them with tweezers, and do not pull out the ear on your own, in order to avoid damage to or infection of the ear canal.
