Save the Ants! (when they're outside)

A few years ago, I made a web page that outlined why people shouldn't kill ants (and included a very scientific chart). I still think ants are all well and good outside, but when they come inside it gets really annoying.

I mean, I'm not going inside ant colonies and stealing their food and stuff, so what gives them the right to come inside my home and start getting all excited over Renaissance's Children's Tylenol? So, I admit it, I've been sucking ants up inside the vacuum cleaner. If this is a sin, God, then I'm sorry.

But they should really stay outside.
