If all your family is effected and they are all willing to read things then you guys can do 5*125000 Ayat Al Kursi. This would definitely kill the Saahir insha'Allah. Another amal is the Azan one. All the family members read Azan day/night. Do 3*125000 times. A family did it once and the Amil who was doing constant Sehr on them, he died. His bones were smashed to pieces.
