ATTENTION: Never stick the device directly into the hill. If you are using
several devices, never install them in the corners of the plot; you then
contain the animals in the middle and block their possible escape routes.
Start repelling the animals directly at the house and work your way toward
the property boundaries. In very dry and hard soil, drill a hole in the ground
and compact the soil around the rod. Look out for underground barriers,
such as pipes, foundations, edges and borders, and concrete slabs! These
barriers reduce the spreading of the frequency waves and their
effectiveness.
Important: Moles and voles in particular will initially try to fight against the
source of the disturbance by increased digging. The unfortunate result of
this activity during this period may be the appearance of more molehills
than before starting to use the device. This is a positive sign that the
animals experience the disturbance in their habitat as unpleasant.
