Spawned Rocket(Clones) still here after scene swap.

Question

Hey, im quite new at game development so this could be a very simple question....

I have 3 object spawners in my game which are spawning clones of a rocket prefab.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class RandomSpawner : MonoBehaviour {
     public GameObject ItemPrefab;
     public float Radius = 1;
     private float nextActionTime = 0.0f;
     public float period = 0.1f;
 
     // Update is called once per frame
     void Update()
     {
         if (Time.time > nextActionTime)
         {
             nextActionTime += period; SpawnObjectAtRandom();
         }
 
         void SpawnObjectAtRandom()
         {
             Vector3 randomPos = Random.insideUnitCircle * Radius;
 
             Instantiate(ItemPrefab, this.transform.position + randomPos, Quaternion.identity);
         }
     }
 
 }

When the rocket hits the player he dies and the scene changes to a 'try again' scene. But when you press 'try again' and come back to the main scene the previously spawned rockets are still there. Is there a way to wipe all the rocket(Clones) of the hierarchy before the scene is swapped to 'try again'?

Thanks in advance!

I solved this as followed:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class DestroyRocket : MonoBehaviour
 {
     // Start is called before the first frame update
     void Start()
     {
         Invoke("Sweep", 1f);
     }
 
     void Sweep() 
     {
         GameObject[] rockets = GameObject.FindGameObjectsWithTag("Rocket");
         foreach (GameObject rocket in rockets)
         {
             Destroy(rocket);
         }
     }
 
     void OnCollisionEnter(Collision otherObj)
     {
         if (otherObj.gameObject.tag == "Player")
         {
             Destroy(gameObject);
         }
     }
 }

This script searches the hierarchy at the start off the game for GameObjects with the tag: Rocket and then deletes all of them.
