The best way to get parasites out of the ears is regular 3% peroxide.
Walmart sells droppers in the eye/ear medicine section. One of the droppers in the 2-pack has a curved tip. This one is for ears.
Lay on your side and place a dropper full deep into your ear. Wait 10 minutes. You may hear a lot of bubbling and gurgling. This will decrease over time. Put a folded paper towel or Kleenex on the ear and turn over. Dry inside the ear as well as you can. Then do the other ear.
You should notice some improvement immediately, but it would be a good idea to do this regularly.
Some consider oil pulling in the mouth and peroxide in the ears a way to keep parasites out of the body.
A bath that is very beneficial for skin parasites is a cup of 20 Mule Team Borax. You can add a cup of Epsom Salt if you'd like.
