CAN WIZARDS KILL DEMENTORS?

Dementors cannot be killed, that's what JK said. They are sort of immortal, I guess. 你 can only protect yourself with Expecto Patronum and if 你 get a Dementor's kiss, well, then your messed up....Since they have no real body, like a living body with mind, 心 and soul, 你 probably couldn't kill them in any way, except maybe weaken them 由 "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 问题 由 the way)

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

I agree with tototo19. As J.K.罗琳 said:"You cannot destroy Dementors, though 你 can their numbers if 你 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 太空 或者 nuke'n it, 或者 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, 你 can just use Expecto Patronum (I don't think I spelled that right) against them.
