The SELECT-A-PEST dial sets the ultrasonic sound frequency 

and has four main groups. These groups are labeled with pest 

names to provide a starting point to target your specific pest. 

Each group has more than one setting to help you dial in The 

Guardian™ to your needs.   Please keep in mind that, just like 

humans, all animals have different hearing ranges. Different 

animals are affected by different sounds - or settings. Most 

importantly, make sure you are giving The Guardian™ at 

least one week on a specific setting before making changes.

Start by selecting one of two options: CONSTANT or MOTION 

DETECTOR. CONSTANT mode sends out a continuous stream of 

unpleasant sounds or wild cat calls. MOTION DETECTOR will only 

send out sounds when The Guardian™ detects movement. 

Moving the PREDATOR SOUNDS switch to YES disables the  

SELECT-A-PEST mode, using predator sounds only. The  

volume of the predator sounds can be easily adjusted 

using the PREDATOR VOLUME dial. 

Ultrasonic sounds are frequencies which are higher than the 

range of human hearing. However, these sounds are very  

irritating to nuisance pests, causing them to flee. 

The range of sounds produced by The Guardian™ include both 

audible and inaudible sounds. Many people can hear sounds 

from both settings 1 and 2, on the SELECT-A-PEST dial.

Although some customers report positive results in a few days, 

we do recommend giving The Guardian™ two to three weeks 

for best results. 

The Guardian™ uses an infrared sensor which detects the  

movement of a heat source, such as an animal. The  

Guardian™ will detect movement up to 100 ft. in front of the 

unit, with a clear line of sight.

The Guardian™ uses pre-recorded mountain lion calls which 

creates a “danger” zone large pests will not want to enter.

The Guardian™ will detect movement and send sounds up to 100 

ft. in front of the unit in a clear line of sight.
