The "SolMate Solar Mole Repeller" by P3 International is my favorite new solar gadget for the yard. It actually drives moles and other burrowing mammals and rodents out of your yard, to a radius of almost 50 feet.
If you're like me, you've been at war with moles and gophers for years and are probably disappointed that the Solar Mole Repeller merely chases them off, rather than releasing tiny solar robots that hunt down and kill the damn things. While the humane process employed by the device may be considered an overly sentimental bug by some of our angrier readers, it's actually an important feature: to pets and kids, the device is perfectly harmless. No poisons or pesticides are involved. Instead, the solar device emits low-frequency pulses through the ground that annoy mammals living down there. After one or two weeks they leave the area. You can place the device wherever sunlight is abundant enough to power its solar cell.
Also, the Solar Mole Repeller is sturdy and unobtrusive - it won't stick out in the garden and you're unlikely to damage it with anything short of a direct strike from a lawnmower blade.
Friendly to the environment and only a little bit mean to moles, voles and gophers, check out the Solar Mole Repeller at Buy.com.
