In earlier posts, I noted that earwigs are rarely (almost never) found in the ear canal. I also noted that the most common insect found in the ear canal is the cockroach. Today the news is buzzing about a moth that crawled in the ear canal of a 12 year old boy in Parker, Colorado. The news story, along with video are here.
The insect in question was a Miller Moth that crawled in the ear canal around dusk. Attempts to dislodge the moth were unsuccessful and the boy taken to the ER. Doctors tried a variety of methods including irrigating the ear canal with water to flush the moth and numbing the ear in an attempt to reduce the pain (the moth was banging against the ear drum) and perhaps kill or stun the moth. This did numb the ear but neither stunned nor killed the moth. Finally, the doctors were able to grasp the moth with forceps and pull it out of the ear canal.
It is not surprising that water would not flush the moth. The ear canal is lined with wax that often keeps water from fully filling the canal. Also, most insects have a cuticle that is water proof and resistant to wetting. Mineral oil is typically more successful at flushing insects from the ear because it does not leave pockets of air in the canal and will soak the cuticle of the insect.
The moth was placed in a urine cup and sent home with the victim as a souvenir. Perhaps it inspire a career in Entomology. However, there are better ways to collect moths.
