Ants inside the ear, i.e. animal foreign bodies in the external ear canal, can often be disposed of by using drops of oil and ethanol, etc. into the ear, and then actively seeking medical attention.
After the ants enter the external auditory canal, they cannot crawl backwards or rotate, and can only crawl towards the eardrum. Therefore, you can choose to face the affected ear upwards first, and use oil or alcohol with a concentration of less than 75% to drip into the ear in sufficient quantity until it overflows, and then the ants can be discharged after sufficient immersion or by buoyancy. If the ants are not discharged by this method, active medical treatment is required.
During transportation, the affected ear can be kept facing upwards as much as possible, which is easy to keep the fluid level in the ear canal and can help to restrain the ants and protect the skin and eardrum inside the ear. A specialist will use specialized equipment and instruments to remove the ants or use saline to flush them out of the ear canal.
When an ant enters the ear, it is important not to panic or stress, and to avoid pulling out the ear and harassing the ants to minimize the resulting collateral damage.
