I don't know about you but I don't get it.
If I have ants crawling through my kitchen, I've got a couple of choices.
If I get all of the food out of the kitchen- guess what? The ants don't have mucvh of a reason to come storming through in a line. They are pretty smart. They figure out that there's nothing there to eat.
I could sit around and poison them enmasse. Might be a bit of a mess but eventually they get the message.
I could plug all of the ways to get into the kitchen. They won't make it in.
Hmmm, and we can't figure out how to deal with illegal aliens.
Maybe we ought to make a mountain out of an ant hill.
