An easy and humane alternative to poisons, gasses and traps. Made of rustproof zinc-plated steel, the Mole Chaser uses wind-driven 18 inch windmill-like blades to create an underground vibration so intolerable to moles that they quickly vacate your yard for more tranquil surroundings. Only a soft, occasional breeze makes the blade spin continually. Easy to assemble with a screwdriver. Attach the Mole Chaser to the top of several feet of 1/2 inch rigid pipe (not included) and mount the pipe in the ground. Made in the U.S.A.
