Scientists have discovered that by recording the sounds that bark beetles make, tweaking them, and then blasting the sounds back at the beetles, they can disrupt mating, tunneling, and reproduction, thus creating a virtual wall around the effected areas of the west.The scientists have developed a device that would be drilled into the outer layer of the lodgepole pines and other trees that beetles favor, pumping the sound waves under bark. Costing about $100 a tree, it’s cheaper, less environmentally disruptive, and far more effective than other methods.Read more over at The Adventure Life.
