Here, I gather, is the patent (from 2014): https://www.google.com/patents/WO2012078814A3 https://www.google.com/patents/WO2012078814A3 "Use of acoustics to disrupt and deter wood-infesting insects and other invertebrates from and within trees and wood products "The invention comprises a device and method for impacting the behavior of invertebrates that infest wood, without the use of chemicals. In particular, the invention is useful for impacting the behavior of woodboring invertebrates, which infest wood products, lumber and the woody portions of plants and trees. The invention utilizes acoustic (sonic) agents which may be optionally modulated with specific signals, to cause negative effects on the normal behaviors exhibited by wood-infesting invertebrates, which may result in the invertebrates being injured or killed, unable to reproduce, or caused to flee the wood that the invertebrates are infesting."
