Does NavMeshAgent disable a gameObject's collider?

I have a series of GameObjects controlled by NavMeshAgents in my scene. They all have BoxColliders attached. They’re supposed to be destroyed when they enter certain triggers in the scene, but none of the OnTrigger* functions are ever called. They’re called for other colliders, but none that have NavMeshAgents.

Is this a known issue? By design?

turns out they didn’t have Rigidbodies attached. Even though I’m sure I double-checked that. But yeah, the OnTrigger* functions need a rigidbody.
