Additional Information
MoleMax Mole & Gopher Sonic Repellent Spikes / Stakes , Solar Powered mole and gopher repellent spikes offer a poison free way to drive away moles, gophers and other underground lawn destroying rodents. Sonic pulses penetrate the soil, emitting a penetrating sound which is irritating to moles and gophers who are virtually blind and extremely sensitive to sound and ground vibration. This encourages moles to leave the property, and the solar operated spike continues to discourage return visits. One solar charge will last up to 5 days. The spike is built with a mow-over design and safe to use around pets. Allow 7-14 days before ground rodents start to move away from the area. Made in USA.
