The pest recognize the pest management devices as a living foe

The introduction of an electronic pest management device in your house or garden means that your pest all of a sudden find themselves with a competitor for the actual area, a competitor that in the end will prove to be a lot more persistent than the pest.
Once you have initiated electronic pest management in your house you might experience for instance the mice to have increased in numbers or to be more active. Let us assure you, they don´t breed that quickly! The increased activity is just the stress induced on them when they try to fight the new enemy.

The mole attacks!
For the same reason as above moles or voles might start digging very close to the Mole Stop device trying to scare it away. A common misconception here is that the device, contrary to what it is supposed to do will attract the pest, but this is not the case. It is merely a good sign of the device having the desired stressing effect on the moles/voles.
