Victor Solar Powered Sonic Spikes offer a poison-free way to drive away moles and gophers. The sound from these pulses irritates moles and gophers, which are virtually blind and extremely sensitive to sound and vibrations. This method encourages moles to leave the property and continues to discourage return visits. No batteries are required to operate the waterproof solar spike and the single solar charge will last up to 5 days. The spike is built with a mow-over design for your convenience and is safe to use around pets. Allow 7-14 days before moles and gophers start to move away from the area.Effectively repels moles and gophers with sonic frequenciesSonic pulses penetrate the ground every 30 secondsSonic frequencies radiate in a circular pattern
