Protecting lawns, gardens and grounds from Mole Damage

Moles are a pest because of the damage they do to lawns, formal gardens, fairways, greens and sports grounds as they dig their tunnels. Molehills and mole ridges spoil lawns, greens and flower beds, while their tunnelling damages the roots of young plants and exposes stones that can damage garden machinery. The natural habitat of moles is woodland but they are very comfortable in gardens, grasslands, golf courses, sports grounds, bowling greens, cricket pitches or where crops are growing.

Moles in the Garden

A mole problem can quickly establish itself and cause significant damage. Moles have litters of up to seven pups and as they mature into adults, each mole will want to establish its own tunnel network and will dig at speeds of up to 4 metres per hour. Little can be done to prevent moles from entering your property - all that can be done is to eradicate the problem once they have appeared.

Signs of a mole problem

It is unlikely that you will see moles as they rarely come above ground, but take care if you trap a live mole as they have very sharp teeth and will bite. Instead, the first sign of a mole problem will be several mole hills or mole ‘ridges’ caused by tunnelling.

The mole digs two types of tunnel:
- Shallow tunnels just below the surface of the ground, as they search for food. These can be seen as a raised ridge in a lawn or flower bed.
- Deep mole tunnels are 10 to 40cm underground. The tunnels cannot be seen, but mole hills are caused by the soil being cleared as the mole digs. Moles will line areas of tunnel with grass and leaves to create nests.

Moles feed on worms but supplement them with insects and their larvae. Moles have a poor metabolism and have to eat their weight in food every day, which can deplete the soil of worms. Since moles cannot put on body fat, they have to eat throughout the winter and do not hibernate. As a result, they are most active in the autumn and early spring.
