Do battery powered ultrasonic devices that are buried in the garden really chase away moles, burrowing rodents, etc?
I am considering buying one of these devices. A: According to the Purdue University Plant and Pest Diagnostic Library, “People should beware of false claims about schemes to drive moles away. Many books and magazines having to do with gardening and landscaping, have references or advertising concerning bizarre strategies to control moles. These include putting mothballs, human hair, razor blades, or chewing gum in their tunnels, or using pinwheels or ultrasonic devices to scare moles away. The reality is that these just do not work.” Other devices on the market include motion-activated sprays from your garden hose, and noise-makers. In general, the reason mechanical devices do not work is that animals get used to them and realize they are not going to cause them any danger.
