Just doing a bit of Ant research and ran across this article where we can learn something about our house pets, eh pests!
"Wonder! Hopefully, this project will also cause you to wonder about the value of ants in the environment. Do they do anything useful? Do you ever see them visiting flowers? Do you ever see them attacking and dragging back noxious insects to their colony? Do you think that ants might be good for keeping some aspects of the environment clean? Wonder about these things, and then see if you can make any observations that support your ideas. Now let's get started with first things first!"
