According to the Johannesburg Metro Police Department (JPMD), at least 80 illegal structures have been demolished in Alexandra by the Red Ants.
The residents erected housing structures illegally near the Juskei River following violent service delivery protests in the township.
The police and private security are on the scene to monitor the situation.
However, the residents are accusing the local government of treating them unfairly.
The community alleges that the red ants came unannounced and started demolishing their houses.
One resident claimed that her two-bedroom house, where she was staying with her kids was also destroyed.
There are also unconfirmed reports that a child died during the demolishing of structures.
