Mole repellent can be, at times, a good way to control moles. These animals are insectivores. As a result, they burrow underneath gardens and lawn seeking grub, mites and ants, which can be a good thing. They have huge appetites, because their way of life requires a lot of energy expenditure. They are quite active during the day, digging and burrowing tunnels under the earth. At night, they are also quite active, eating, digging and creating their intricate tunnel systems. However, once they start to overpopulate they begin to cause damage to expensive lawns and gardens. This is where their usefulness stops. It is at this point, that homeowners need to begin thinking about the different types of mole repellent that are available for mole control.
