Ants in the ear can be treated with ear drops in oils and solutions such as ethanol, and active medical attention.
Ants burrowing into the ear will mostly crawl in the external auditory canal and produce itching and obvious foreign body sensation in the ear. Under the guidance of the doctor to rule out tympanic membrane perforation or other contraindications, take the affected ear towards the upper head position, choose oil and ethanol solution with a concentration of 75% or less to drop the ear, and prompt the ants to be discharged out of the ear canal with the overflowed liquid through the effect of buoyancy.
If the ants do not float after a few minutes, it is necessary to actively consult a doctor to clarify the condition of the external auditory canal and the status of the ants. For those with intact eardrums, warm saline is usually used to rinse the external auditory canal to flush out the ants. If the eardrum is perforated, the ants can be sucked out or removed with the help of professional instruments.
Once the ants get into the ear, you should stay calm and avoid blindly pulling out the ear or harassment to minimize the unnecessary damage.
