To Deter Plague of Bark Beetles, A Boombox Blasting Bug Sounds
[T]he NAU scientists started by blasting rock music and backwards recordings of Rush Limbaugh (presumably because playing the Rush Limbaugh recordings forward is a punishment too terrible even for the beetles). Unfortunately, the beetles quickly became immune to the sounds of heavy metal and heavy bloviating.
The researchers then struck back with an even more annoying sound: recordings of the beetles themselves.
It worked with then bugs, but would it work with Rush? Somehow, I think not.
