I was told to hum or sing God Save the Queen when I have an infestation. So far it has worked. What is really odd is that melody doesn't stick in place of the recently ousted one. For fun sing the Renn and Stimpy Royal Canadian Kilted Yaksmen Anthem to that melody.

Our country reeks of trees
Our yaks are really large
And they smell like rotting beef carcasses
And we have to clean-up after them
And our saddle sores are the best
We proudly wear women's clothing
And searing sand blows up our skirts
