Ok, Rembrandt, I will amend what I said to this extent; it is smart to use natural controls in an intelligent way.
In the case of mongoose and kudzu was any significant research was ever done prior to their release into the environment? I'm sure it was not. Big difference.
Unless we can figure out how to bring back continent ice sheets to scour North America clean kudzu is here to stay. Its free, its like heat resistant spinach, its covers the south so..
Some recipes:
Kudzu rice quiche (I don't care for quiche myself.)

from this site:
"It's everywhere! So we might as well do something with it. Every part of the Kudzu plant is usable. Try young Kudzu leaves in place of spinach. Deep fried Kudzu leaves are like potato chips. Do a pot of rolled stuffed Kudzu leaves instead of using cabbage... Use the root powder in place of cornstarch and for frying squash or other vegetables....... Make Kudzu wine!"
