CAN WIZARDS KILL DEMENTORS?

Dementors cannot be killed, that's what JK said. They are sort of immortal, I guess. You can only protect yourself with Expecto Patronum and if you get a Dementor's kiss, well, then your messed up....Since they have no real body, like a living body with mind, heart and soul, you probably couldn't kill them in any way, except maybe weaken them by "grounding" them somewhere not near to people...

but i don't know, if they can't get multiplied is it always the same number of them? (intereting question by the way)

No, they can just repel them with "Expecto Patronum"...

I agree with tototo19. As J.K.Rowling said:"You cannot destroy Dementors, though you can limit their numbers if you eradicate the conditions in which they multiply, ie, despair and degradation."

Dementors can not be killed!! we only can protect ourselves from them with our Patronus!!

ummmmm........i think they can overpower them with expectro patronum.....

I think there would be a way to destroy a dementor. Like launching it out into space or nuke'n it, or something horable like that...

I don't think they can be killed. They can just be repeled. Because they are already sort of dead. . so, you can just use Expecto Patronum (I don't think I spelled that right) against them.
