I get many many clones on my scene when I go back to editor

Unity Engine

I have a code that creates a flash when certain object ceases to exist. For that purpose I used OnDisable()
The problem now is that when I stop the game, I get many flash(Clone) all over my scene, and I have to erase them manualy. Can I fix this issue?
Debug lets me knows that “Some objects were not cleaned up when closing the scene”
How do I clean these cloned objects automaticaly?

Here’s the code

var flash : Transform;

function OnDisable()
{
	Instantiate(flash,transform.position,transform.rotation);
}

If the flash happens to be made with a particle system, you can enable the Autodestruct option on the particle animator to destroy it when the system has finished. Otherwise, you should call Destroy on the object once the flash effect has run its course.
