Now there's something you don't see everyday!

Had a customer that had a refrigerator that wouldn't come on.  I checked it out and found ants in the cabinet.  LOT'S OF ANTS!  
I checked the power board and found the ants had gotten behind it and shorted the board.  The customer sprayed and killed what she taught was all of the ants, but they just kept showing up.  I was not getting any power to the optical board in the front of the refrigerator and couldn't figure out why.  I removed the refrigerator and discovered the answer.  The ants had built their colony inside the refrigerator.  Not only had they eaten away the styrofoam insulation, but they also ate the insulation around the wires going to the optical board.  
A new refrigerator was installed!  The following photos tell a better story, Enjoy!  By the way, all of the little brown spots are ants.
