Man vs Ants

Question.  Do ants have the mental and/or psychological capability to learn behavior?  I am hoping yes, but hypothesising no. 

I woke up this afternoon to find a bevy of them had advanced on my desk.  I took the standard procedure when dealing with ants [crushed them] and traced their comings and goings to a specific path coming from the door.  I disrupted the path and as the ants scattered I thought that my point had been made.  [Don’t come on my desk or I will crush you with a Post It note.]

Fifteen minutes later, the ants have once again begun their march to [and up onto] my desk.  Again, I beat them back.  Now, I am wondering if they will learn from the destruction of their fellow kind and retreat from the desk permanently.  I am guessing that if empty Code Red can are involved, the answer will be no.
