Cockroaches entering the ear can be fully soaked in oil and ethanol in the external ear canal, and observe whether the cockroaches will be discharged with the overflowing liquid, or actively consult a doctor for treatment.
Cockroaches entering the ear can be treated in the position of the head with the affected ear facing upwards, using oily liquids such as sesame oil, rapeseed oil, or ethanol with a concentration of 75% or less to drip into the ear, which may be discharged from the external auditory canal along with the liquids due to buoyancy, and then the cockroaches will float out of the external auditory canal. Even if the cockroach is not discharged, it can still adhere and bind the cockroach’s activities, reducing its further damage to human tissues.
When the cockroach is not discharged after sufficient resting, you can actively consult a doctor to have the ear canal examined by a specialist through specialized equipment and select professional instruments and means to remove the cockroach.
After cockroaches have entered the ear, avoid blindly pulling out the ear, shining light on the ear and patting the outer ear, so as to reduce the irritation and harassment of cockroaches and the unnecessary damages to human body as a result.
