Trigger activating before entering trigger. What do I do?

Code:

 using UnityEngine;
 using System.Collections;
 
 public class Switch : MonoBehaviour
 {
     GameObject Ball;
 
     // Use this for initialization
     void Start()
     {
 
     }
 
     // Update is called once per frame
     void Update()
     {
 
     }
 
     void OnTriggerEnter(Collider coll)
     {
         if (coll.gameObject.tag == "Ball")
             Debug.Log("Ball Entered! :)");      
             
     }
 
 }

I have two objects. A ball, and a box. When the ball enters the box (which is marked as a trigger) it should do something (in this case send a message to me in console). Problem being is that it is activating before it ever hits the trigger. What do I do?

Is there any consistent behavior to when it's triggering? Such as randomly, only when you're moving toward it from a certain distance, etc?

Check the collider of the box (should show as a green outline when it's selected) and make sure it isn't somehow set larger than it should be.

@Ninamori As OncaLupe suggested, have a look at the collider on the box and make sure it is not to large, do the same with the ball game object. Maybe the ball has a larger collider.

You can also have a look in the scene rather then the game play when you start. The script has no errors or not that I can gather.
