CAN WIZARDS KILL DEMENTORS?

Dementors cannot be killed, that's what JK said. They are sort of immortal, I guess. tu can only protect yourself with Expecto Patronum and if tu get a Dementor's kiss, well, then your messed up....Since they have no real body, like a living body with mind, corazón and soul, tu probably couldn't kill them in any way, except maybe weaken them por "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 pregunta por 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 tu can their numbers if tu 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 el espacio o nuke'n it, o 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, tu can just use Expecto Patronum (I don't think I spelled that right) against them.
