Spiders crawling into the ear should be sought as soon as possible at the ENT department of the hospital, where they will be removed by a specialized doctor.
After the spider and other foreign objects enter into the ear, you must not handle them at home by yourself, because various stimuli such as sound and light may make the spider continue to move towards the eardrum, which may cause the eardrum to be broken in serious cases, leading to hearing impairment, and in severe cases, secondary infection leading to suppurative otitis media.
Therefore, when the above situation occurs, it is necessary to avoid stimulating the spider that enters the ear, and then seek medical attention as soon as possible. After examination by a doctor to determine its location, the spider will be anesthetized or killed by drops of ethanol, etc., into the ear, and then removed or rinsed out with tweezers.
