Not sure if you've ever checked out SimAnt on the old Mac, but it really helps to break down the life of ants in an interesting and interactive way. It should help you understand and gain an appreciation for those fascinating creatures.

A MacAntFarm would be interesting. Maybe gut an iMac G5 for that?

Never have tried Borax, but baking soda also gets rid of them. Worked for me when I saw some on a baseboard. They never came back and its been two years.
