Mambabarang (summoner) is a witch who uses insects and spirits to enter the body of any person they hate. A Mambabarang is a kind of a mangkukulam. Mambabarangs are ordinary human beings with black magic who torture and later kill their victims by infesting their bodies with insects. They are different from Mangkukulams - the latter only inflict pain or illness. Mambabarangs use a strand of hair from their chosen victim and tie it to the bugs or worms which they will use as a medium. When they prick the bug, the victim immediately experiences the intended effect.
