An Aldi customer said he found numerous insects crawling in a bag of pasta when he opened it.
Justin Pilgrim, from Kettering, Northamptonshire, was left "sickened" by the discovery in his 29p penne on Wednesday.
The 24-year-old filmed the bugs writhing around inside the packet and posted a video to social media.
As the clip begins, Justin is seen holding up the bag of pasta to the camera.
He then zooms in to reveal a small, black insect trapped between a piece of the penne and the plastic.
After that, Justin pans the camera across the rest of the bag to reveal more bugs crawling through the tube-shaped snack.
The horrified shopper took to social media to complain to Aldi about the "beetles".
He posted the clip saying: "Nice trip to the shops, hope there are no more packets like this.
"And the woman who refunded me took about an hour to and was rude as hell when I wanted my money back."
Speaking today, he added: "I felt sick looking at them, there were literally hundreds of them.
"I have no clue what they were, some kind of beetle-looking things.
"The woman was pretty rude with me when asked for a refund and didn't get it for a while.
"I was just waiting around for her to come back. It might not have been a lot of money, but it was the principle."
An Aldi spokeswoman said: "We are sorry to hear of Mr Pilgrim's experience and apologise that this product did not meet our usual high standards.
"We have spoken with Mr Pilgrim and provided him with a full refund."
However, Justin says he is disappointed with Aldi's response.
He said: "I'm not really satisfied, I would have liked a better response but oh well."
Mirror Online has approached Aldi for comment.
