Here is a picture of a standard solar mole repeller:

Some may come with an additional LED light to brighten up your garden during the night and there a few colors to choose from. While the repeller uses sound waves to drive away moles, they cannot be heard by humans so do not worry about the repeller driving you crazy. Most domestic pets should also not be effected as the repeller sends its vibrations through the soil in your garden. The range that the repeller is effective for varies depending on your spoil type but most repellers will guarantee a 20 meter radius in any soil type and up to 1200 meters in optimal soil.
High quality solar powered repellers will happily recharge even on cloudy winter days so do not think you need to live in a desert to get it to work properly. No batteries are needed so it’s a simple matter of plugging it into your lawn and forgetting about it.
The technology behind the repeller is quite simple yet very effective. The repeller will send vibrations using sound waves at a particular range of frequencies through the ground. The mole or rodent that you wish to get rid off will interpret this range of frequencies as an intruder into its home and will act on its natural instinct to run away. As long as the vibrations continue the animal will not return to its home again at a later date as it will believe that the intruder is still present. The mole will then move on to a new location to start dwelling a new home.
It is recommended to purchase two mole repellers if you have a front and back yard as the foundations of your house are likely to prevent the vibrations from travelling from the back garden to the front or vice versa. Owners of large gardens might want to buy additional mole repellers to make sure the mole will not relocate to a distant part of your garden instead of leaving altogether. The general rule of thumb is that one repeller will work over a 20 meter circular radius as a minimum so make sure you have enough to cover your entire garden.
