The Pestrol Rodent Free unit has been used effectively in homes and wide a range of different business settings throughout New Zealand and Australia for well over 10 years.

Please note the product is made of a Fire Retardant case and the unit has a inline safety fuse plus has undergone the NZ and Australian electrical and safety tests.

One unit is required for a very small home with 2 units plus for larger homes…Each level requires an additional unit. If the wiring in the home is older more units can be required so that the entire area is covered. The average sized home will require two or more units with larger homes requiring 3 to 5 units.

Buying one unit for a larger home will not keep the rodents away and will not work. Units should be spaced throughout in larger buildings.

These rodent repelling units utilizes a combination of Electromagnetic, Ultrasonic and Ionic technology to protect the desired area from rats, mice and even assists with the control of cockroaches. Our units are effective to provide a stress free solution. Allowing for peace of mind, in thousands of New Zealand homes and businesses, for the past 10 years. By choosing to use a Pestrol Rodent Free device you are helping to protect your family and friends as well as protecting our environment from the dangerous effects of harsh chemicals and poisons that are commonly used in traditional pest or rodent control products.

Many customers use this product for their family homes, businesses and holiday homes to safeguard their property from Rodents and help control Cockroaches.

As the weather gets cooler the rodents start to look for somewhere warmer such as your walls and ceilings.

What is Electromagnetic, Ultrasonic and Ionic technology?


The Electromagnetic technology used in the Pestrol Rodent Free utilises the existing wiring within the walls of your home or building by simply sending random computer generated pulses through the wires. This pulsing is tuned to directly affect the rodents and cockroaches nervous system. The electromagnetic technology is the main/most powerful defense of this unit to protect your home against rats, mice and cockroaches.

Electromagnetic pulses converted to random computer generated intervals ensuring the rats, mice and cockroaches will not build up a tolerance. Vibrations caused by the unit are felt by the pests, making it almost impossible for them to gather food, breed, communicate and build their nests. The pulsing ensures the rodents and cockroaches vacate the area covered to regain comfort and quality of life.

Pestrol Rodent Free Electromagnetic Field


The Ultrasonic technology is a high frequency sound emitted from the unit. This is designed to be outside of the typical human hearing range. The Pestrol Rodent Free Ultrasonic frequency emits a pulse or wave that disturbs and disorients rodents and cockroaches, driving them away from your home or business. Similar to the effect of the Electromagnetic pulses this 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, although the electromagnetic pulses will go on to cover the remaining of the 150m2 of your home through the wiring circuit.

Using a variable pulse generator, the Pestrol Rodent Free emits fluctuating sound waves ensuring pests do not become accustomed or immune to the Ultrasonic waves.


Ionic technology works to emit electrically charged negative atoms 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 a large weather change or lightning storm, cockroaches, rodents and other animals sense a change in the environment. You may notice just before a storm many animals will become unsettled, change their behaviour and begin looking for protection and coverage away from the incoming storm.

The Pestrol Rodent Frees’ Ionic function mimic’s the electrical charge of an incoming storm throughout your home or business, transforming your area into a hostile environment. Pests become confused and frightened, causing them to seek shelter far from the range of any Pestrol Rodent Free product.

Besides making your area a deterrent against pests, the Ionic technology constantly works to purify the air you breathe, helping create a pest free and healthy environment within your home or business.

The Pestrol Rodent Free is extremely effective at repelling rats and mice and helps with the control of cockroaches. We recommend using Pestrol cockroach traps in conjunction with the Pestrol Rodent Free as their eggs can lay dormant for 6-12 months before hatching and beginning the cockroach cycle again.

We recommend these our Pestrol Rodent Free device to be used in any home; business; apartment; batches; schools; club houses; café; restaurant; bar; dairy; bakery; warehouse; hall; boat; factory or anywhere you may experience rat, mice or cockroach problems.


How many units will I need to cover my home or business?

We recommend 1 unit to protect/cover 150 m2 (a small 1-2 bedroom home.) If your home is multi level, you will also need at least one unit per level. In older homes or businesses you may require an extra unit especially if the wiring is say more than 20 years old. Buying less units than required will mean the product will not keep the building free of rodents!

How long until the unit works?

It will take between 3-10 days on average for the unit to take full effect and drive the rats and mice away. Sometimes it may take up to 21 days for the unit to take full effect. Please be aware that it can take a little longer with cockroaches as their eggs can lay dormant for many months before hatching.

You may see an increase of rodent and cockroach activity within this time. Be assured this is a very good sign and shows that the Pestrol Rodent Free unit is working and causing discomfort for the pests, driving them away from their hiding places, looking for an escape route. You may wish to set some bait or traps during this time to catch the pests. You can ensure that they have an escape route, such as an open door or window.

Where should I put my Pestrol Rodent Free?

You can plug the Pestrol Rodent Free anywhere around your home or business. Using the above guide or calling us to determine how many units you may need for your home. We advise to have one on each level of your home, or alternatively at each end of your single story property. If you have the luxury of electric plugs in your roof or wall cavities it is recommended to place a unit there as well as within the living areas of your home.

The Pestrol Rodent Free is recommended to be plugged directly into a power point rather than an extension cord or multi adaptor, approximately 0.5 metres from floor level in an unobstructed area. This allows the Electromagnetic pulses to achieve maximum coverage throughout your home or business. The unit will still be effective if it is placed above this height or has small barricades in its path.  There is no need to install an electric outlet in the ceiling area.

Please be aware that the Ultrasonic waves cannot pass through solid objects and or bend around corners or barricading objects.

Will it affect my children or pets?

No. This unit will not affect adults, children or pets. Some small children or animals with highly sensitive hearing may pick up on the Ultrasonic waves. This however is very rare and the high frequency sound will not affect them. If you are worried or do find this an issue you are able to change the setting to only use Electromagnetic pulsing.

What is the life span of my Pestrol Rodent Free?

The unit comes with a 60 Day money back guarantee* and a 2 year warranty on the unit*.  We have found that the unit should work for 5-10 years normally. If you do find any problems or the lights on the unit stop working just call us on 0800 88 88 44 and we are more than happy to help you.

Are the lights supposed to be flashing on the unit?

Yes, the yellow (ultrasonic) and red (electromagnetic) lights will constantly flash on the unit. This is normal and does not mean your unit is not working properly. This is because these two technologies will turn on and off so the rodents and cockroaches will not build up a tolerance to the unit. The green (ionic) light is more subtle than the red and yellow lights, and this light will stay on constantly, not flash on and off. The night light (blue light on top of the unit) will not flash either.

Should I have the unit on all the time?

We recommend having the unit running constantly as this will provide the best protection for your home.

Can I have traps and baits set up with this unit in place?

We recommend not to have any traps or bait set in your home when using the Rodent Free. As this unit works to repel rats, mice and cockroaches, baits will attract the rats and mice into your home which will counteract the Rodent Free Unit.

How much Power does the Pestrol Rodent Free use?

The unit uses the same power as a  3 Watt light bulb. This means it will only cost a few cents a week to run.

*60 day guarantee from May 1st 2014 and subject to Pestrol T’s & C’s
* 2 year warranty is subject to Pestrol T’s & C’s.
