From the Manufacturer

The Molechaser is the easiest way to get rid of moles, voles, gophers, shrews, and other burrowing rodents. Made of sturdy high impact materials, the Molechaser is weather proof and proven effective. Penetrating sonic pulses of 300 Hz at 15 second intervals irritate burrowing rodents and motivates them to move to a more comfortable home. The unit can be buried flush with your lawn, allowing easy mowing without detracting from the look of your landscape. The Molechaser's patented battery cylinder allows you to change the batteries while the unit remains in the ground. With a battery life of 4 to 6 months and a lifetime warranty, the Molechaser is very cost effective, convenient and reliable.
