unity - How can I do something only after an animation has finished?

I'm making this 2D platform based game. Basically what I want is when the player walks into spikes (which have a "deadly" tag") it displays the animation that has the parameter of animate with the value of 3 and after that the player gets destroyed. So my question is:

• How do I build a timer or something so that the object only gets destroyed after the animation is played (with no looping)?

This is the code I'm using now:

void OnTriggerEnter2D(Collider2D target) {
    if (target.gameObject.tag == "Deadly") {
        Die();
    }

}

void Die() {
    animator.SetInteger ("AnimState", 3);
    Destroy (gameObject);
}
