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. Rodents will get disturbed once the Rodent Free is plugged in. It will take from 1-7 days normally to get of rodents from a building. In some cases, it may take 14 or even up to 30 days to get rid of all rodents in unusual circumstances. This is based on feedback from customers and general field testing over 12 years.


How does it work?


Rodent Free Pro makes use of three technologies:  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.


Ultrasonic Rodent Control


The Ultrasonic technology utilises a high frequency sound which is emitted from the unit at intervals. This Ultrasonic sound is not normally audible to humans.

The Pestrol Rodent Free uses a variable pulse generator that switches the unit off and on, ensuring pests do not become accustomed to the technology. The varying high frequency sounds 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.


Ionic Technology


Ionic technology is a complementary to rodent control.

Ionic technology has been used for many years in the Air Purification business throughout New Zealand and Australia to help purify the air you breathe.

  • Size: Height: 13cm Width: 7.7cm Depth: 6.5cm (approx.)
  • Power: AC 240 V/50HZ
  • Power consumption: 8 Watts (Max.)

    Professional to deal with. Prompt delivery.

    I had a major problem with rats inside my house and had bait laid for over two weeks. I rang up in desperation and found Pestrol helpful particularly the speedy delivery under lockdown 3. Unfortunately there was a rat living in the fold of my Roman blind which the Pestrol Rodent free device did nothing to scare off despite placement very near the unbeknown ( to me ) rat. I have now got rid of the rats via poison and plugging up the weatherboard holes. I’m hopeful the Pestrol devices will scare away any further rodents but that remains to be seen. It certainly isn’t a quick fix. Have to say I haven’t noticed any other spiders, moths etc.

    No more rodents after installing 3 units throughout the house. Wife now happy.

    Sadly rats continue to come in the house despite having three units .
    Fear it’s been a waste of money

      These rodent Free pros are actually amazing. Before purchase the house I stayed had a bad problem with mice, rats & cockroaches running and crawling around the house and now after two weeks since I’m glad to say that I haven’t seen any since.

      See a recent review received today.

    waiting to see if the resident rat leaves

  10. Nicola Johnston (verified owner)

    Very easy to order and super fast next day delivery. However, I did not receive a confirmation email or receipt. This would have been helpful as the products were bought for a rental property and I can claim with the receipt.

  11. John Clegg (verified owner)

    Excellent very prompt service

  12. Bianca Kelsey

    We have one, and it’s great! Took about 10 days before it completely kicked in and removed all rodents! Best thing we bought!! Would love a couple more for our barn and outdoor sleepout!
