How can I tell if the pest repellers are working?
Quite simply the pest will go away, but there are other ways. The units have LED’s to indicate that the unit is functioning correctly. You may also experience an increase in pest activity within the first few weeks of use. This is due to the effects of the unit disorientating and agitating the pests. So hostile will your home become, that the pests may enter the property from cavity walls or loft areas, in an attempt to escape. It is important to stress that this does not happen very often.
