Unity : How do we destroy gameObject and particle effect on it on destroy?

DestroyAndParticle.cs

void KillEnemy()
    {
        ParticleSystem vfx = Instantiate(deathParticlePrefab, transform.position, Quaternion.identity);
        vfx.Play();
        float destroyDelay = vfx.main.duration;
        Destroy(vfx.gameObject, destroyDelay);
        //destroy patciles 
        Destroy(gameObject);

    }
