Unity2D Destroy doesn't get rid of game objects,Gameobject Destroy not destroying object

In my game, I have balloons appear on the screen (they are instantiated). I want all of the balloons on the screen to be destroyed to then spawn new ones.

 public void resetBalloons(){
         tempBalloons = GameObject.FindGameObjectsWithTag("Balloon");
         foreach(GameObject ballon in tempBalloons){
            Destroy(balloon);
         }
 ...

This is the code that is meant to destroy the balloons, but for whatever reason, all of the balloons remain. I have confirmed that the function is being called the correct amount of times through Debug.Log() calls, so the function is running, and the FindGameObjectsWithTag is finding the balloons too. Just for whatever reason, it is ignoring the Destroy function.
