In addition, phrasal verbs like cast out or drive out could work too, depending on the context:
and to have authority to drive out demons.
(http://biblehub.com/mark/3-15.htm, the NIV translation)
Cast out is often used in modern biblical translations:
That evening they brought to him many who were oppressed by demons, and he cast out the spirits with a word and healed all who were sick. (Matthew 8:16; quoted translation is ESV)
Out of the 53 translations of this verse included in that link, a strong plurality (26) use cast out.
As defined by MW, the phrase indicates driving out, or expelling.
I don't disagree that exorcise is a more specific verb for OP's context, but I would just point out these usage figures from Google Books...
to exorcise the ghost - about 4,150 results
to lay the ghost - about 9,230 results
That's sense 23 in thefreedictionary...
lay - to quiet or make vanish: to lay a ghost.
'Exorcize' would be the correct term.
In addition to the other fine answers posted, I've heard the phrase "dispel evil spirits".
Exorcise is probably the right answer, but you may also consider purify depending on the context.
For example, a Catholic priest uses a purificator to purify his fingers and the chalice from evil before blessing and handling the Eucharist. The priest does not exorcise his fingers or the chalice, but he is still getting rid of evil.
If the evil described is not a specific evil spirit(s), but evil itself, you'd want to use purify.

His rejoinder to it here is to point to the other parts of the same ritual, and to ask why, then, infants are exorcised and exsufflated in baptism. For, it cannot be doubted that this is done fictitiously, if the Devil does not rule over them ; but if he rules over them, and they are therefore not falsely exorcised and exsufflated, why does that prince of sinners rule over them except because of sin?

One more answer: Ward off spells may fit.
For example: The wizzard warded off the spell casted by the witch.
The word adjure does not specifically mean the warding off or banishing of spirits but often arises in that context. The definition is to urge or command (someone) to do something, and it is used in the context of exorcism at times, most famously perhaps in this passage from the King James Bible (Acts 19:13),
Then certain of the vagabond Jews, exorcists, took upon them to call over them which had evil spirits the name of the Lord Jesus, saying, We adjure you by Jesus whom Paul preacheth.
Basically, "In the name of Jesus, I command you to get lost."
