Based on what mythos you believe in, you would either have to:

A. Destroy their totems of power, rendering them weak enough to be killed.

B. Convert all their followers, so they have no worship.

C. Destroy the Heart of the West (If you've read Percy Jackson).

D. Cut them up into pieces and scatter them across Egypt (If you know the story of Osiris)

E. Get another God to kill them

That's all I can think of at the moment.
