What and how long do fruit flies live in your ear?

Fruit flies, typically living about 30 days, do not naturally reside in human ears. If a fruit fly were to enter the ear, it would likely become disoriented and unable to survive due to the lack of food and appropriate environment. In rare cases, if a fly gets trapped, it may cause discomfort or irritation, but it would not live long. Seeking medical assistance is advisable if a fly is stuck in the ear.
