Doctors in China found an unusual cause for a patients ear problems: There was a spider in there and it was building a nest.

According to The South China Morning Post, the patient in Jiangsu, China north of Shanghai reported an intense itch in his ear and went to the hospital last month.

I didnt notice it when inspecting [his ear] with the naked eye , Dr. Zhang Pan, of the Affiliated Hospital of Yangzhou University, told The Sun. However, using an endoscope, I discovered the small spider inside.

The spider was caught on camera as it spun a web in the patients ear canal.

Making matters worse, the elusive arachnid moved too quickly to be caught with instruments and had to be flushed out, UPI reported,

Wash your ears well tonight. Then, maybe wash them again.

Just in case.
