You never know just what kind of underground pests you’re going to run into, so why not stay safe rather than sorry? The Solar Underground Pest Deterrent device won’t harm the environment in any way, and it won’t add to your monthly electricity bill since it comes with a built-in solar panel. Powered by the sun, it will help help drive away underground pests including moles, voles, and gophers.

The weatherproof anodized aluminum spike stakes into the ground, where it emits sonic vibrations every 30 seconds that irritate burrowing pests and compel them to disperse. The deterrent operates within a diameter of 94 1/2′, and the 4″ sq. solar panel charges an integrated battery during the day, even in low light and overcast conditions, so it operates both day and night. The panel fully charges within three hours in full sunlight conditions and will operate for up to eight hours on a full charge.

Nice to know that it comes with a replaceable rechargeable battery pack, all for $59.95 a pop. If dad’s an avid gardener and have been complaining about underground pests, why not get this for him?
