Moles can be a real nuisance in gardens. By digging underground tunnels for food, they are able to ruin the landscape in a matter of days. This is how the famous molehills are formed. Not to mention that moles can cut the roots of plants and damage seeds. It is therefore important to act quickly because a mole gives birth to six cubs per year on average. Indeed, if you have 10 moles in your garden, you could have about forty by the following year.
