Where to position your Mole Stop

The closer to the burrows of the moles / voles the better. Also, the firmer the ground the better the device will function. The waves dispersed are roughly circular in shape and the radius of effect is normally 15-20 metres (800 - 1200 square metres). Concrete slabs, large stones or garden ponds disturb the wave pattern and therefore reduce the effectiveness.
Vegetable or flower beds or mole hills are unsuitable sites since the ground is too soft and will reduce wave dispersion. Moreover, moles and voles nest in firm ground and often outside the garden perimeter, i.e. in quieter surroundings.
