A Mambabarang (summoner) is a witch who uses insects and spirits to enter the body of any person they hate.
Mambabarangs are sorcerers who use black magic to torture and later kill their victims by infesting their bodies with insects.
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. They are different from Mangkukulams - the latter only inflicts pain or illness.
