particle effect activation

Hi im trying to get a particle effect to start after 10 seconds to cover an asset when it gets destroyed


public GameObject objectToDestroy; 
public GameObject effect; 

void Update () 
		Instantiate (effect, objectToDestroy.transform.position, objectToDestroy.transform.rotation);

		Destroy (objectToDestroy, 10f);

		Debug.Log ("Plasma Fire destroyed");


I have similar code in other scripts to do the same think but they also include on trigger enter/exit while this is automatic after 10 secs

Any suggestions as to where im going wrong?

Use an IEnumerator to destroy GameObject
