This reminds back in the day I had a Canon Lide 20(I think) that had real small ants in it. I mean a lot of them. The odd thing is there were no other by or in my computer, nor the room it was in. I never knew how they got in there and survived. I just put it in a garbage bag and threw it away. I still live in the same house and that has not happened again. I wonder if they got in during manufacturing. Here is a link, who would have thunk it.
