Setting up the deterrent device:

There is a switch on the left side of Rodent Free device. When you plug in the device in mains, make sure the switch is all the way to the bottom so that all the three technologies are active in repelling the rodents.

How does it work?

Rodent Free Pro makes use of three technologies to repel the rodents : Electromagnetic, Ultrasonic, Ionic.

Electromagnetic Rodent Control and Deterrent

The Electromagnetic technology used in the Pestrol Rodent Free utilises the existing wiring within the walls of your home or building by simply sending pulsing or shifting signals through the wires. This pulsing is tuned to directly affect the pest’s nervous system. The signal is turned on and off at set intervals so that rodents and cockroaches don’t build up a tolerance. Electromagnetic vibrations irritate the pests and they tend to stay away. The electromagnetic technology is the most powerful defence of this unit to protect your home against pests.

Ultrasonic Rodent Control

The Ultrasonic technology utilises a high frequency sound which is emitted from the unit at an interval. This Ultrasonic sound is not audible to humans. The Pestrol Rodent Free Ultrasonic frequency emits a pulse or wave that disturbs and disorients rodents and cockroaches so they don’t become accustomed to the environment. The high frequency sound creates a very uncomfortable environment for the rats, mice, and roaches making it almost impossible for them to communicate, breed, gather food, nest, and live their daily lives.
The Ultrasonic sound waves cannot pass through solid objects and walls. The Ultrasonic sound emitted from this unit will be effective in the room that you have placed the unit in. Using a variable pulse generator, the Pestrol Rodent Free emits fluctuating sound waves ensuring pests do not become accustomed to the effect of the technology.

Ionic Rodent Control

Ionic technology emits electrically charged negative ions that are very common in our atmosphere. Negative ions are produced naturally by lightning before a storm. Animals are naturally sensitive to negative ions and you may notice that long before lightning storm, cockroaches, rodents and other animals sense a change in the environment. Many animals become unsettled, change their behaviour and begin looking for protection from the incoming storm. This device’s Ionic feature mimics the electric charge of an incoming storm throughout your home or office, transforming your area into a hostile environment. Pests become confused and frightened and tend to seek shelter far from the range of any Pestrol Rodent Free product.
Besides making your indoors pest free, the Ionic technology constantly works to purify the air you breathe, helping create a pest free and healthy environment within your home or business.1

  7. Geoff Wake (verified owner)

    Hard to comment on a product when it’s just installed given it says it may take weeks to work….

  8. Toni (verified owner)

    Amazing product… didn’t think it would work but it has…

  9. Brett Collins (verified owner)

    Product finally arrived (after originally being sent the wrong product) Immediately plugged both Rodent Free Pro units in. Wow, did they create a party of chaos in our roof. The first night was a constant fury of scurrying and panic as the rodents in our roof dealt (unsuccessfully) with these bad boys’ electro magnetic pulses through our home’s wiring. From the 2nd night onwards, we have enjoyed complete and total silence – We are rat and mice free. Hallelujah!

  10. Sharon Whittle (verified owner)

    I am rating at 3 only because it is a bit too soon to say if the gadget is working as expected. The online shopping experience, speed of arrival and efficiency deserve a 5+

  11. Felicity (verified owner)

    Great service and great product – it worked for us – thank you! So nice to have NO mice!

  12. Pauline B. (verified owner)
