Mole Control from Rentokil

Protecting your Garden from Mole Damage

Moles are a pest because of the damage they do to lawns as they dig their tunnels.

Molehills and mole ridges spoil lawns 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 residential gardens, grassland or where crops are growing.

Moles in the Garden

A mole problem can quickly establish itself and cause significant damage.

Moles

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 tunnels:

  • Shallow tunnels that moles dig 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.

How to get rid of moles

With the extensive damage caused by moles, there are many mole control products on the market. However, in our experience, trapping and fumigation are the only reliable solutions to a mole problem.

DIY products can be used, but very often professional mole control will be required.

DIY mole control

Do not believe the stories of repelling or killing moles by putting broken glass, pepper or other substances into the tunnels – this will not work. The mole will dig around the disturbance which may even cause more damage

However, garden centres and hardware stores sell amateur products that can help with a mole problem:

Ultrasonic mole repellers

In our view, these devices have limited effectiveness because ultrasonic sound does not travel underground. At best, these may encourage moles to move a short distance and dig new tunnels.

Trapping

Mole traps are best used in the autumn and spring when moles are most active. For rapid results, it is advisable to use several traps on the deep tunnels, although this can be expensive for a one-off problem.

Take care when setting traps and follow the instructions carefully to avoid injury.

Check traps everyday for moles that have been caught but not killed.

Fumigation

Some retailers sell fumigants for use against moles. Phosphin is sold by Rentokil but only to persons with a valid MX-certificate.

These products are potentially very dangerous if misused - take great care and follow the manufacturer’s instructions carefully.

Professional Mole Control

While DIY products can deal with smaller mole problems, a professional pest control service will probably be required for larger outbreaks of moles on your property.

Rentokil offers a call-out service to deal with moles and other pest problems in the home and garden. Our service is fast, effective and offers the highest level of safety for your family and pets.
