Happened to my sister when we were kids. She got a junebug in her ear and it went so deep you couldn’t see it. We filled her ear with peroxide, which seemed to kill it, but she still couldn’t hear.

The nurse said she was making it up and just had too much earwax. We did peroxide rinses every day until it fell out a week later. Probably not very safe to have a bug rotting inside you, but we already owed a couple hundred for the nurse to dismiss us so we definitely weren’t going back to the hospital.
