According to The New York Post, a farmer was raising them and someone reportedly broken into the critters' plastic greenhouse and they escaped.
The New York Post says the bugs took off from a nursery in western China where they were being raised for use in traditional Chinese medicine.
In China, scientists take extracts from the bugs and use them to treat cancer and reduce inflammation.
Folks who live nearby are being told to stay calm, and that farmer is taking a huge financial hit.
He was expecting to make around $160 for every two pounds of cockroaches he sold.
