The commission says it has warned the company to observe the law when its staff carry out their duties.
The SAHRC's Buang Jones said the commission had expressed its concern with the South African Board for Sheriffs.
"The manner in which the Red Ants conduct themselves does not respect the rights that are enshrined in the Constitution and they have to be taken to task. It is something we will raise with the Red Ants.

"If needs be, we will take legal steps."
The commission will summon the mayor of Emfuleni to explain whether the law was followed when the court in the Rustervaal eviction order was carried out, said Jones, adding that a report would be compiled after the SAHRC met with the mayor and the affected communities next week.
On Thursday residents blocked the R82, saying they wouldn't allow those living in the informal settlement to remain in the area.
They have accused the group of committing crimes including rape, murder and theft.
