One the the videos showed Ms Vile peeling the gold foil off one of the chocolate pieces and pointing to the wriggly creatures. She found more maggots upon opening another piece of chocolate.
"Never eating these again!!!! This is what my roommate and I found. Maggots in every single one," she wrote in the post.
The video, with over 49 million views on Facebook, made people squirm with disgust.
"I can never eat these again," wrote a user.
"Wherever they were stored there must have been flies around I'm never eating them again either yuck," wrote another.
Ms Vile stated in the post that the 'best before' date on the box was March 6, 2018. She told NDTV that she has written to the company and is waiting for a response from the chocolate manufacturer.
A company spokesperson told Daily Mail that their products need to be "stored carefully" and they advise specific storage conditions that are mentioned on the product packaging.
