Can humans hear ultrasonic pest repellers?

As we already discussed, humans and animals generally cannot hear the ultrasonic pest repellents because of its frequency range. People can hear on the frequency from 20 Hz to 20 kHz. The ultrasonic devices are most of the time above 20 kHz. ... The operating frequency of such devices passes unnoticed for most of us.

Does ultrasonic pest control work on mice?

Sonic or ultrasonic devices have been touted as repellents for everything from roaches to insects to rodents, specifically rats and mice. ... However, there is little data that these devices repel insects or are effective in rodent control. Rats and mice emit high-pitched sounds and may communicate using these sounds.

Crystals of materials such as quartz vibrate very fast when electricity is passed through them—an effect called “piezoelectricity.” As they vibrate, they manipulate the air around them and the fluids they come in contact with, producing ultrasound waves.

How do you use Pestrol?

The Pestrol Rodent Free will need to be plugged into a power point approximately 0.2 metres from floor level in order for the ultrasonic to run along the ground, living rooms and hall ways. Ensure the unit is placed in an unobstructed area for the ultrasonic waves to achieve maximum coverage.
